WHAT YOU CAN RUN

31 use cases. 150+ apps. One predictable price.

Each use case below names the SaaS you'd be leaving, the open-source apps that replace it, and the team shapes we see most often. Every app in the catalog runs at €9 per month, fully managed — security, backups, updates, monitoring, and 24/7 support included.

Most teams arrive here after a SaaS renewal cycle: a HubSpot Pro quote that climbed past comfort, a Slack 90-day retention warning, a Calendly per-seat ceiling, a Bitwarden tier change, a Zapier task-overage email, or a privacy review of GA4 with a client or auditor. The math stops working before the team is ready to leave, and the operational cost of self-hosting an alternative is genuinely high — patching, backups, SMTP, DNS, on-call.

This page maps 31 common jobs-to-be-done to the open-source software in the DANIAN catalog. We run each app for €9 per month, fully managed, in the region you choose, across 21 datacenter locations on six continents. You get the data ownership, the cost predictability, and the customisation an open-source application gives you, without the time cost of operating it.

USE CASE 01 / 31
Automate your workflows

From €9 /app/month 

The trigger: Zapier's task-overage email arrives mid-launch, mid-funnel, mid-month — and a quick check shows the next tier costs more than a full DANIAN-hosted alternative.

Workflow automation in this category spans three jobs at once: connecting your apps to each other, triggering scheduled or event-driven tasks, and orchestrating multi-step processes that run without supervision. n8n is the catalog's flagship — over 400 native integrations, a visual workflow editor, JavaScript code nodes when you need them, and self-hosted vector-database support for AI-augmented flows. Typebot handles conversational forms and chatbot logic. Mautic runs the marketing-automation half of the same problem space. Home Assistant and OpenHAB extend the same logic to physical-world automation — lights, sensors, EV chargers via Evcc.

Common setups: a 5-person SaaS team running n8n for billing-event automations and webhook orchestration; an agency using Mautic to run drip campaigns for 12 client brands without per-contact pricing; a small e-commerce shop using Typebot to qualify leads at the top of the funnel before handing off to a human; a smart-building installer running Home Assistant for 30 client sites under one dashboard. Workflow data, credentials, and execution logs stay on your instance. Migrate workflows in via the JSON export from your existing tool.

Sync and share files across teams

From €9 /app/month 

The trigger:Dropbox Business and Google Workspace stack into a four-figure annual bill for storage you barely use, and a privacy-policy review surfaces awkward US data-flow questions.

File sync software in this category covers personal cloud storage, team file sharing, large-file transfer, partner SFTP drop-zones, and the calendar-and-contact sync layer that sits alongside files in most teams' day. Nextcloud is the catalog's broadest tool — files, calendars, contacts, video calls, document editing, and a plugin ecosystem that covers most office-suite shapes. SFTPGo handles SFTP/FTP/WebDAV access for partners and clients who need to drop or pick up files via standard protocols. Pairdrop provides AirDrop-style local transfer in the browser. Radicale serves CalDAV and CardDAV for calendar and contact sync without the rest of Nextcloud's surface. MinIO covers S3-compatible object storage when you need programmatic access.

Common setups: a 12-person consultancy using Nextcloud for shared client folders with OnlyOffice integration for collaborative document editing; a media production team running SFTPGo for client deliverables (5–50 GB per file) without exposing internal infrastructure; a privacy-conscious household running Radicale plus Nextcloud Calendar to keep family schedules synced across iOS, Android, and desktop without iCloud or Google. Per-user access controls, full audit logs, encryption at rest, and external-share expiry are part of the included service.

Run team chat, voice, and video

From €9 /app/month 

The trigger:Slack's 90-day retention starts deleting conversations the team needed for an audit, a contract dispute, or a postmortem — and the paid tier's per-seat math hits a wall at the next hire.

Real-time communication here spans team messaging, video calls, voice rooms, federated chat, broadcast streaming, and the support inbox that sits at the company-customer boundary. Mattermost is the catalog's primary team chat — full unlimited message history, voice channels, plugin ecosystem, role-based access. Rocket.Chat adds livechat widgets and cross-channel messaging at scale. Element on Matrix provides federated chat that works across organizations without forcing them onto your server. MiroTalk P2P, SFU, and Broadcasting cover one-to-one calls, group video conferencing, and live broadcast respectively. Greenlight on BigBlueButton runs structured online classrooms. TeamSpeak handles persistent voice rooms.

Common setups: a 25-person remote agency running Mattermost with custom slash commands and a Greenlight room for weekly all-hands; a small university running Element plus MiroTalk SFU for departmental chat and seminar calls without per-seat-per-term licensing; a Mastodon instance bridged to Matrix for community-managed group conversations alongside the Fediverse feed; an online-tutoring platform using Greenlight as the primary classroom tool. Message history is unlimited, federated where supported, and exportable. We handle the SMTP, the TURN/STUN servers, and the daily off-site backups.

Build internal tools without code

From €9 /app/month 

The trigger:Airtable's per-record limit bites mid-quarter, or Retool's per-user fee compounds, and the team is still building the same admin dashboard quarter after quarter.

Software in this category turns spreadsheets and databases into functional apps — admin panels, internal tools, lightweight CRMs, inventory trackers, and custom dashboards. NocoDB and Baserow are the spreadsheet-as-database front ends — both Airtable-style interfaces backed by Postgres or MySQL, with role-based access, view sharing, and auto-generated REST APIs. Directus is the headless-CMS angle — manage any database through a clean admin UI and serve content via REST or GraphQL. PocketBase bundles authentication, file storage, and realtime data into a single binary, ideal for app backends without separate database operations. Formbricks handles in-app surveys and feedback widgets without per-response data-export limits. n8n closes the loop with workflow automation between these tools.

Common setups: a 6-person operations team using NocoDB to run their entire customer pipeline as a multi-table base with role-based views per department; a freelance developer building three client portals on PocketBase, each isolated and white-labelled; an agency using Directus to power blog content for 12 client websites from one admin interface; a product team using Formbricks for in-app NPS, churn surveys, and feature-request collection. Schema changes, API keys, and full database backups run from the dashboard. Migrate from Airtable via the standard CSV export.

Run a CRM or ERP

From €9 /app/month 

The trigger:The HubSpot quote climbs past Pro tier and the team uses 20% of the features — or Salesforce Essentials renews at a price that doesn't match what the 3-person sales team actually does.

CRM and ERP in this category cover contact management, sales pipelines, deal tracking, customer notes, invoicing, and the lightweight project ledger that ties them together. EspoCRM is the catalog's primary CRM — pipelines, contacts, opportunities, custom modules, full activity history, and a clean mobile UI. Dolibarr is the European-flavoured CRM/ERP all-in-one — same CRM core plus invoicing, inventory, accounting, HR, and project management modules in one application. Chatwoot consolidates customer conversations across email, chat, and social into the customer record. InvoiceNinja closes the loop with branded invoices, recurring billing, and payment-gateway integration. HumHub adds an internal social-collaboration layer for teams that need it. CryptPad covers encrypted client-document collaboration alongside the CRM.

Common setups: a 4-person consultancy running EspoCRM with Mautic for marketing automation and Chatwoot for inbound chat — three apps, €27 per month total; a 15-person trades business running Dolibarr for unified CRM, quotes, invoicing, and stock; a freelance studio billing clients via InvoiceNinja with EspoCRM tracking the pipeline behind each invoice; a B2B distributor running Dolibarr with EDI integrations for supplier orders. Your contact data, pipeline data, custom fields, and activity logs export at any time. We handle the patches, the daily backups, the SMTP, and the SSL.

Add AI features without sending source data away

From €9 /app/month 

The trigger:The team wants generative AI features inside the tools they already use, but a privacy review draws a hard line on shipping source documents to OpenAI, Anthropic, or Google by default.

The AI angle here is integration, not standalone. Nextcloud Hub ships Smart Pickers — generative-text, translation, image generation, and dictation features that plug directly into Nextcloud Files, Talk, Mail, and Deck. The same instance you already run for files and calendars gets AI assistance built in, with the model running either locally (via the Local AI app), against your own self-hosted Llama 3 or Mistral, or via a controllable third-party connector you choose. The privacy boundary stays where you set it. Prompt logging, model selection, and per-user access controls run from the same dashboard as the rest of Nextcloud.

Common setups: a 30-person law firm running Nextcloud with Smart Pickers configured to use a self-hosted Llama 3 instance for document summarisation — sensitive client files never leave the firm's infrastructure; a content team using Nextcloud's AI translation across team-shared documents in 6 languages without a separate translation SaaS; a research collective using Nextcloud's dictation-to-text to transcribe interview recordings into searchable notes; a 10-person product team using AI-assisted email triage in Nextcloud Mail. The category is intentionally narrow — primarily Nextcloud's AI surface plus the open-source LLM stack you can bolt on to it. If you need a different open-source AI stack provisioned (Open WebUI with Ollama, LibreChat, Flowise, AnythingLLM), email and we can scope a custom deployment.

Track product and web analytics

From €9 /app/month 

The trigger:A privacy review of GA4 by a client, an auditor, or a marketing freelancer surfaces the consent-banner-and-data-flow problem — and the team needs analytics that don't require a 200-word cookie disclaimer.

Analytics in this category covers two distinct stacks: web analytics (the GA4 replacement) and BI/observability (the Looker, Datadog replacement). Matomo is the catalog's primary GA4 alternative — page views, sessions, funnels, e-commerce tracking, heat maps, no sampling, full data ownership. Umami and Ackee are the lighter, privacy-first options when Matomo's surface is more than the team needs. On the BI side, Metabase and Apache Superset connect to your Postgres, MySQL, BigQuery, or Snowflake and give the marketing or ops team self-serve dashboards. Grafana plus Prometheus and Alertmanager is the catalog's observability stack — server metrics, application metrics, alerting, on-call. Beszel covers lightweight server health monitoring. Redash handles SQL-driven dashboards.

Common setups: a 3-person SaaS team running Matomo for product analytics and Metabase for revenue dashboards — €18 per month for what GA4 plus Mixpanel would charge per seat; a privacy-conscious agency hosting Matomo for 8 client sites with separate accounts and full data isolation; an internal IT team running Grafana plus Prometheus for 24/7 server monitoring with alerts wired to Slack; a 12-person e-commerce team using Umami for cookieless web analytics across 4 storefronts. Data stays in the region you pick. Export anytime in standard formats (CSV, Parquet, raw SQL).

Host Git repositories and CI/CD

From €9 /app/month 

The trigger:GitHub Enterprise pricing arrives at the next renewal and the team is twelve people, not twelve hundred — and the per-seat math no longer makes sense for a codebase that ships twice a week.

Code hosting here means Git repositories with CI/CD, issue tracking, pull-request review, package registries, and the lightweight project-management layer that sits next to a real codebase. GitLab is the catalog's full-stack option — repositories, CI runners, container registry, package registry, issue boards, and merge-request review in one application. Gitea and Gogs are the lighter alternatives when the team needs Git hosting and issues but not the full DevSecOps surface. Verdaccio serves as a private npm registry for proprietary packages. Redmine adds a heavier project-management and ticket-tracking layer when an engineering org wants more than GitLab's issues. Pair these with Woodpecker CI from the Automation category for a complete CI/CD pipeline.

Common setups: a 10-person product team running GitLab for repositories, CI/CD, and package management — single tool, single price, no per-seat math; a 3-person dev studio on Gitea for client codebases that can't go to a US-hosted SaaS; a JavaScript-heavy agency running Verdaccio alongside Gitea to publish private npm packages used across client sites; a 25-engineer org migrating off GitHub Enterprise to GitLab self-hosted with full CI/CD parity at a fraction of the per-seat cost. Migrate from GitHub or Bitbucket via the standard Git import — repository history, issues, and pull requests come over.

Edit, sign, and archive documents

From €9 /app/month 

The trigger:The team's document workflow lives across Google Docs, DocuSign, Notion, and a shared drive — nobody can find the latest version, and the renewal-cost spreadsheet shows four separate line items.

Document software in this category covers four overlapping jobs: real-time collaborative editing (the Google Docs / Microsoft 365 replacement), e-signature workflows (the DocuSign replacement), digital archives and OCR (the paperless office), and structured knowledge-base or note-taking layers. OnlyOffice Docs is the catalog's primary office suite — full-fidelity Word, Excel, and PowerPoint editing with real-time collaboration, integrated with Nextcloud or standalone. OnlyOffice Enterprise handles the heavier deployment. CryptPad covers end-to-end encrypted collaborative editing for sensitive documents. Documenso and DocuSeal handle e-signature flows. Paperless-NGX runs the OCR-and-archive workflow for scanned receipts, contracts, and invoices. BookStack, Wiki.js, and Documize provide structured wikis. HedgeDoc and Etherpad cover collaborative markdown and plain-text editing. Apache Answer handles team Q&A. Kavita, Calibre-Web, and Komga manage e-book and document libraries. LibreTranslate handles document translation locally.

Common setups: a 20-person professional services firm running OnlyOffice plus Nextcloud for client document collaboration, plus Paperless-NGX for tax-record archives — three apps replacing Microsoft 365 plus DocuSign plus a paid scanner-archive service; a freelance contracts attorney running Documenso for client e-signatures at zero per-document cost; a research team using HedgeDoc for collaborative markdown notes during fieldwork; a small publisher using Calibre-Web and Komga to manage 4,000-title backlists with member-checkout. Documents stay in your region; export to standard formats (DOCX, PDF, EPUB, ODT) any time.

Run your own Fediverse instance

From €9 /app/month 

The trigger:Twitter / X / Instagram / YouTube terms-of-service shifts force a content move, and the team wants distribution it controls — independent of platform algorithm changes, account suspensions, or sudden API price hikes.

Federated software in this category lets you run your own node on the open social web — ActivityPub-based servers that talk to each other across the Fediverse without a central platform owner deciding policy. Mastodon is the catalog's primary microblogging server — your own instance, your own moderation rules, federated to the rest of the Fediverse. PeerTube is the YouTube-shape video federation — content you host, federated discovery, no algorithmic suppression, no Content-ID overhead. Pixelfed handles the Instagram shape with the same federation model. Castopod runs podcast hosting with Podcasting 2.0 features, transcripts, and Fediverse comments. Owncast runs live-stream broadcasts with chat. Matrix plus Element provides federated real-time chat across organizations.

Common setups: a 50-person nonprofit running its own Mastodon instance for organizational comms with strict moderation rules and no advertising; a podcast network using Castopod to host 8 shows with cross-show subscriptions, automated transcripts, and Fediverse replies; a small university running PeerTube to host lecture recordings without YouTube's monetization constraints or copyright-flag false positives; an independent journalist running Owncast for live broadcasts that can't be demonetized mid-stream; a regional photo collective on Pixelfed with shared moderation. Bandwidth scales with usage. Migrate from existing platforms via standard exports.

Store and back up large files

From €9 /app/month 

The trigger:Backblaze charges by GB transfer and the photo library has crossed 500 GB — or the SaaS app's S3 invoice has overtaken the rest of the infrastructure budget on a single bad cache-miss week.

Storage in this category covers object storage (the S3 alternative), encrypted backup targets, photo libraries, music collections, and digital comic and e-book libraries. MinIO is the catalog's primary S3-compatible object storage — drop-in replacement for AWS S3 in your apps, deployed in your region, no egress fees beyond the bundled traffic, full IAM-equivalent policies. Immich is the catalog's photo-library tool — Google Photos shape with facial recognition, on-device backup from iOS and Android, and full data ownership. Navidrome, Koel, and Ampache handle music libraries with mobile and Sonos clients. Audiobookshelf handles audiobooks and podcasts. Komga handles digital comics and manga. Cubby covers personal file sharing. Nextcloud, Paperless-NGX, SFTPGo, and XbackBone round out the file-side storage shapes.

Common setups: a 12-person SaaS team using MinIO as the S3 backend for production file uploads — same code, your region, no surprise egress bills; a family of four running Immich on a single instance for 800 GB of photos with iCloud-style auto-backup from every device; a small library digitizing its archive into Komga and Audiobookshelf for member checkout; a music collector running Navidrome with 40,000 tracks served to phones and home Sonos. Storage scales by additional GB at €0.50 per month each, with full export at any time. Daily off-site backups are part of the included service for every storage app.

Run a forum or community space

From €9 /app/month 

The trigger:Discord limits bot reach mid-launch, Reddit closes API access, the Slack community hits the message-history limit — and the community needs a permanent home it controls.

Community software in this category covers traditional forums, Q&A boards, and the social-network shape of internal communities. Discourse is the catalog's flagship forum — clean, mobile-friendly, plugin ecosystem, real-time replies, and the trust system that quietly does the moderation work. NodeBB is the lighter forum option with strong realtime and notification handling. Apache Answer provides Stack Overflow-shape Q&A for product communities and internal knowledge sharing. HumHub runs an internal social network — profiles, feeds, groups, files — for organizations that want intranet meets community. Mastodon, Matrix, and Owncast extend the same shape into federated and broadcast territory.

Common setups: a 5,000-member developer community running Discourse with SSO from the company's main app and webhook integration into the issue tracker; a 200-employee distributed company running HumHub as an internal social space with private project groups and shared files; an open-source project running Apache Answer to consolidate GitHub Discussions, Stack Overflow questions, and the project mailing list into one searchable archive; a niche-hobby community on NodeBB with custom theming and a dedicated mobile app. Member data, content, and moderation logs export in standard formats.

Track personal and business finance

From €9 /app/month 

The trigger:QuickBooks Online's price hike crosses €40 per month and the freelancer just needs invoices and expense tracking — or a forgotten €19 monthly subscription gets caught at year-end and triggers a wider audit.

Finance software in this category spans personal-finance tracking, business invoicing, subscription accounting, and event ticketing. InvoiceNinja is the catalog's primary business-invoicing tool — quotes, invoices, recurring billing, payment gateways, expense tracking, time logging, and project-based billing. Firefly III handles personal finance: budgets, accounts, transactions, bills, with imports from most major banks. Actual Budget runs envelope-style budgeting with multi-device sync. Wallos tracks subscription costs and renewal dates so you stop discovering forgotten €19 per month line items in next year's audit. Pretix handles event ticketing with full pricing rules, discount codes, and tax-compliance for events.

Common setups: a freelance designer running InvoiceNinja for client billing and Firefly III for personal finances — both on one instance, €18 per month total; a small NGO running Pretix to ticket a 600-person annual conference with VAT-compliant invoicing and country-specific tax codes; a household using Actual Budget across 4 devices to manage a joint envelope-style budget; a small e-commerce shop using Wallos to consolidate the 23 SaaS subscriptions it accumulated during the founder's last build sprint.

Run email marketing

From €9 /app/month 

The trigger:Mailchimp's contact-tier pricing triples after a successful lead-magnet campaign — the agency is still on the same retainer, the list grew faster than the budget did, and the next tier costs more than the campaign earned.

Marketing software in this category covers email automation, lead nurturing, contact segmentation, and the tracking layer behind it all. Mautic is the catalog's primary marketing-automation tool — drip campaigns, segmentation, dynamic content, lead scoring, and full SMTP control. The same tool that HubSpot's lower-cost competitor Marketo costs $36k+ per year for. 

Common setups: an agency running Mautic for 15 client brands with isolated contact databases, branded sender domains, and per-client reporting — at flat per-app pricing, not per-contact; a SaaS company running Mautic for product-led email sequences (welcome flow, trial-conversion, re-engagement) with full SMTP control via Amazon SES, Postmark, or a dedicated SMTP relay; a content marketer pairing Mautic with Matomo for first-party attribution that doesn't depend on cookies. Send reputation, deliverability, and contact-list ownership stay in your control.

Run customer support and help desks

The trigger:Zendesk's per-agent fee crosses three or four seats and the inbox is still mostly the founder's — or Intercom's MAU pricing jumps with every product launch and the support team is still two people answering tickets in 12 hours.

Customer support software in this category covers shared inboxes, ticket queues, customer feedback boards, scheduling, surveys, and the chatbot layer that handles tier-zero questions. FreeScout is the catalog's lightweight Help Scout alternative — shared mailbox, ticket assignment, customer profiles, internal notes, native Gmail/Outlook integration. osTicket runs the heavier ticketing surface for teams that need multiple departments and SLA tracking. Fider collects customer feature requests with public voting. LimeSurvey and Formbricks run customer satisfaction and product feedback surveys. Typebot adds a chatbot front for FAQ and ticket triage. Rocket.Chat covers real-time support escalation.

Common setups: a 4-person customer-success team using FreeScout as the central shared inbox with Slack notifications for follow-up calls — €18 per month total; a 12-person SaaS support team on osTicket with department routing, SLA tracking, and Mautic-tied automation for proactive outreach; an open-source product using Fider as a public roadmap so customers can vote on what gets built next; a B2B-services team running LimeSurvey for quarterly NPS and customer-effort surveys with branded look and feel.

The trigger:Asana, Monday, or Jira invoice the agency for seats nobody opens — and the deal still bills monthly. Or the team needs Gantt-level project planning and the per-seat ramp doesn't fit a 25-person studio.

Project-management software in this category covers task boards, sprint planning, time tracking, asset management, and the lightweight project-collaboration layer that surrounds them. OpenProject is the catalog's heaviest tool — Gantt charts, agile boards, time tracking, baseline planning, document management, fit for engineering and construction-style projects. Taiga is the focused agile/scrum option for software teams. Kanboard and Wekan run lightweight Kanban boards. Leantime targets early-stage projects with strategy and execution layered together. Loomio handles group decision-making and consensus voting. Kimai handles dedicated time-tracking and invoicing-feed for hourly billing. Snipe-IT manages physical-asset inventory (laptops, equipment). Redmine, Mattermost, and JupyterHub round out the project-collaboration shapes.

Common setups: a 25-person agency running OpenProject for client-project Gantt scheduling and Kimai for time-on-project tracking, exported to InvoiceNinja for billing — three apps replacing Asana plus Harvest plus an accountant; a 6-person dev team running Taiga for sprint planning and Wekan for personal Kanban; a small school district running Snipe-IT to track 400 student laptops with check-in / check-out workflows; a worker-cooperative using Loomio for consensus decisions on bylaws and operational changes. Project data, time entries, and asset histories export in standard formats.

Add live chat to your website

From €9 /app/month 

The trigger:Intercom's MAU pricing jumps with every product launch — and the chat is still answered by the same two people who answered it last quarter, just with more invoice line items now.

Live chat software in this category covers website chat widgets, customer-facing real-time conversation, AI/chatbot triage, and the unified inbox that catches messages from chat, email, social, and SMS. Chatwoot is the catalog's primary customer-engagement tool — chat widget, omnichannel inbox (email, Instagram DM, WhatsApp, SMS, Twitter), customer profiles, automation rules, mobile apps for agents. Rocket.Chat extends to internal chat that shares the same backbone as customer chat. FreeScout adds the structured help-desk layer for ticketed conversations. Typebot serves the AI/chatbot front so frequent questions never reach a human.

Common setups: a SaaS team running Chatwoot on three product subdomains with Typebot handling tier-zero questions before human handoff — total cost €18 per month for what Intercom would charge $300+ at the same volume; an e-commerce store using Chatwoot to centralize chat, email, Instagram DMs, and WhatsApp Business into one agent inbox; an agency white-labelling Chatwoot for client websites with the agency's branding intact and per-client routing rules; a small SaaS using Rocket.Chat livechat as the front door to its support flow with conversation hand-off to FreeScout for asynchronous follow-up. Conversation history, customer data, and chat transcripts export in standard formats.

Host photo and gallery libraries

From €9 /app/month 

The trigger:Google Photos' shared-album limits bite mid-trip, the iCloud bill ticks up year over year, and the family photo archive — 10 years of birthdays and holidays — needs a permanent home.

Photo and gallery software in this category covers personal photo libraries with mobile sync, collaborative family albums, artist portfolios, and the recipe-archive use case (Mealie) that sometimes lives next to the family photos. Immich is the catalog's primary Google Photos alternative — facial recognition, on-device auto-backup from iOS and Android, timeline view, map view, shared albums, full original-resolution preservation. Piwigo runs the more curated photo-archive shape — ideal for clubs, museums, and professional photographers who need taxonomy and metadata. Lychee provides a clean portfolio-style gallery for creatives. Pixelfed adds the Instagram-shape federated-photo layer. Nextcloud Photos covers the lightweight integration when photos sit alongside files. Mealie handles recipe collections with structured data, meal planning, and shopping-list generation.

Common setups: a family of four backing up 12,000 photos and 800 videos to Immich with auto-recognition labelling everyone — replacing two iCloud Plus subscriptions and a Google One plan; a wedding photographer using Piwigo to give clients private gallery access with download permissions and watermark options; a community gardening group running Mealie to share 200 seasonal recipes alongside Piwigo for produce photos; an architectural-photography studio using Lychee for client-facing portfolio sites with custom theming. EXIF data, original-resolution files, and album metadata stay yours.

Run an internal wiki or knowledge base

From €9 /app/month 

The trigger:Confluence renews at $5.50 per user per month and most users open it twice a quarter — or Notion's per-user fee adds €15 of unread doc space to every new hire.

Wiki software in this category covers internal knowledge bases, structured documentation, public reference wikis, and the personal-knowledge-management shape (Trilium, HedgeDoc) that overlaps with note-taking. BookStack is the catalog's most popular choice for SMB teams — clean WYSIWYG editing, books-and-chapters structure, role-based access, full-text search. Wiki.js targets the same surface with markdown-first editing and tighter Git integration. MediaWiki is the heavier option (the engine behind Wikipedia) for public reference wikis or large internal documentation projects. DokuWiki keeps it simple for teams that don't want a database. Omeka S handles structured archive collections for museums and libraries. Trilium Notes covers personal knowledge management with hierarchical notes and relations. HedgeDoc, Documize, JupyterHub, and Redmine cover the adjacent collaboration shapes.

Common setups: a 30-person engineering team running BookStack for internal docs (runbooks, onboarding, architectural decisions) with SSO from the company SSO; a small museum using Omeka S to publish a digital archive of its collection with structured metadata; a research student using Trilium Notes for thesis notes with cross-document linking and citation management; a 12-person nonprofit running DokuWiki as the public-facing knowledge base for grant guidance and project archives. Content versioning, full markdown export, and audit logs are part of the included service. Migrate from Confluence, Notion, or Google Sites via available export tools.

Manage team passwords and secrets

From €9 /app/month 

The trigger:Bitwarden's free-tier tightening, a 1Password Business renewal that climbs past comfort, or a security-review finding that engineering team members keep production secrets in plain text on local machines.

Password and identity software in this category covers business password management, secrets management for engineering teams, multi-factor authentication, and single sign-on. Vaultwarden is the catalog's primary password-manager — Bitwarden-compatible server, full mobile and browser-extension support via the same client apps Bitwarden ships, organization sharing, role-based access. HashiCorp Vault handles infrastructure-secrets management for engineering teams: API keys, certificates, dynamic database credentials, secret rotation policies. 2FAuth runs a self-hosted authenticator-app backend so the team's MFA codes don't sit in one engineer's phone alone. Keycloak provides full single sign-on (SAML, OIDC) when password-management isn't enough and you need centralized identity across all your apps.

Common setups: a 15-person company running Vaultwarden for shared business passwords with separate vaults per department — €9 per month flat regardless of seat count, replacing what 1Password Business would charge per user; a DevOps team using Vault to inject database credentials into containers without hardcoding, with automatic rotation every 24 hours; an SMB running Keycloak as the SSO layer in front of Vaultwarden, the wiki, the project management tool, and the support inbox — one credential, one MFA setup, full audit trail; a small engineering team running 2FAuth alongside Vaultwarden so MFA codes survive a lost or stolen device. Audit logs, encrypted backups, and standard import from existing tools (LastPass, Dashlane, 1Password, Keeper) work out of the box.

Run developer and design tools

From €9 /app/month 

The trigger:The engineering team's tool budget fragments across 12 SaaS subscriptions, the CFO asks whether half could move on-prem, and a quick audit shows €600 per month spent on tools half the team forgot they had logins for.

Developer tooling in this category is broad — design (the Figma alternative), translation and localization, URL shorteners, notification services, private package registries, remote-desktop gateways, PDF utilities, link archiving, and assorted developer utilities. Penpot is the catalog's primary Figma alternative — full design editor with prototyping, design tokens, and team libraries. Weblate handles translation workflows for software products with 50+ language support. LibreTranslate covers programmatic translation. LanguageTool handles grammar and style checking. ntfy provides a simple HTTP-to-notification bridge for monitoring alerts and personal automations. Guacamole gives browser-based RDP, SSH, and VNC. Stirling-PDF handles PDF manipulation. Linkwarden archives links with full-text search of snapshots. Kutt and YOURLS run branded URL shorteners.

Common setups: a 12-person product team running Penpot, Weblate, and Verdaccio — three apps, €27 per month, replacing roughly $400 per month of equivalent SaaS; an internal IT team running Guacamole as the browser-based gateway to internal RDP and SSH hosts (no VPN client required for end users); a side-project developer running Kutt for branded short URLs and Linkwarden for link archiving with automatic snapshots; a content-marketing team running LanguageTool plus LibreTranslate for grammar-and-translation workflow without sending content to a third-party SaaS. API access, role-based teams, and standard export formats apply across the category.

Invoice clients and accept payments

From €9 /app/month 

The trigger:Stripe's invoicing add-on and FreshBooks' subscription stack together for what was supposed to be a simple billing operation — and the freelance designer just wants to send a quote and get paid without a four-tool integration.

Invoicing and payment software in this category covers business invoicing, recurring billing, payment-gateway integration, and event ticketing with paid registration. InvoiceNinja is the catalog's primary tool — branded invoices, quotes, recurring billing, payment-gateway integration (Stripe, PayPal, Authorize.net, and 40+ others), client portal, time-tracking, and project-based billing. Pretix handles event ticketing with VAT-compliant invoicing, discount codes, attendee data ownership, and integration with payment gateways. The combination covers most SMB invoicing scenarios outside heavy double-entry accounting workflows (which fall under Finance).

Common setups: a freelance designer running InvoiceNinja for monthly client billing with auto-recurring invoices and Stripe Connect for direct bank deposits — total cost €9 per month, replacing a $25-per-month FreshBooks subscription plus Stripe's invoicing surcharge; an event organizer using Pretix to ticket a 1,200-attendee conference with multi-currency support, early-bird discounts, country-specific tax codes, and proper VAT-invoicing per attendee; a small SaaS using InvoiceNinja for B2B annual contracts where Stripe Billing's per-invoice surcharge added up faster than the team expected; a workshop educator using Pretix for course-cohort registration with capacity-management. Invoice templates, payment-gateway choice, and client-data export are all in your control.

Schedule meetings and appointments

From €9 /app/month 

The trigger:Calendly's per-seat math hits the five-seat ceiling and the team still has a sixth person who books meetings — or a CalDAV-compatible calendar is needed for the family that won't go to Google or Apple.

Calendar and scheduling software in this category covers appointment booking, group scheduling, calendar sync (CalDAV), and shared availability calendars. Rallly handles the group-poll style scheduling — pick a meeting time across N participants, no accounts required for invitees. EasyAppointments runs the appointments-with-clients shape — service catalog, booking page, customer profiles, calendar sync, automated reminders. Open Web Calendar publishes calendar feeds in a clean web format for embedding into sites. Radicale provides the CalDAV/CardDAV backend so calendars and contacts sync across iOS, Android, Outlook, and Thunderbird without a Google or Microsoft account.

Common setups: a 6-person consultancy running EasyAppointments as the public booking page on three service lines, with notifications and reminders going through the same instance; a community organization using Rallly to schedule 15-person board meetings without forcing everyone onto a single calendar platform; a privacy-conscious household running Radicale across 4 family members' devices for shared family calendar and contacts without iCloud or Google; a small medical practice using EasyAppointments for patient bookings with automatic SMS reminders. Calendar data, contacts, and booking history export in standard ICS and vCard formats. Migrate from Calendly or Acuity via standard CSV import.

Publish a blog, podcast, or video

From €9 /app/month 

The trigger:Substack's revenue-share kicks in at the first paying-subscriber milestone, or a personal blog needs comments without Disqus's tracking pixels — and the creator wants to own the audience and the data.

Content and blog software in this category covers the publishing surfaces beyond traditional WordPress: video, podcast, jupyter-notebook publishing, internal social-publishing, and the comment-system layer. PeerTube handles video publishing with federated discovery and full data ownership. Castopod runs podcast hosting with Podcasting 2.0 features (chapters, transcripts, value-for-value), integrated analytics, and Fediverse-comment integration. JupyterHub publishes data-science notebooks at scale for technical content and educational publishing. HumHub adds an internal social-publishing layer for organizations. Comentario provides a privacy-respecting comment system for any static or dynamic site (Disqus replacement). Monica HQ tracks personal contacts and content (the personal-CRM angle, often used by content creators to remember who's who).

Common setups: a niche video creator running PeerTube to host long-form content without YouTube monetization rules or copyright-flag false positives; a podcast network using Castopod for 6 shows with cross-show subscriptions, transcripts, value-for-value Lightning payments, and a single hosting bill; a static-site blog using Comentario for moderated comments without sending visitor data to a US ad-tech company; a data-science educator publishing tutorial notebooks via JupyterHub directly to readers. Content, subscriber data, and engagement metrics export in standard formats. Migrate from Substack via the standard subscriber export.

Run private search and SEO tracking

From €9 /app/month 

The trigger:The team needs to query the web programmatically and Google's Custom Search API pricing makes the use case a non-starter — or an SEO agency wants rank-tracking without paying $499 per month for the all-in-one tool whose other modules nobody uses.

Search software in this category is narrow — it covers private metasearch (SearXNG) and rank-tracking for SEO (SerpBear). SearXNG is a metasearch engine that aggregates results from Google, Bing, Brave, DuckDuckGo, and 70+ other sources without sending the user's query to any of them directly. It's the catalog's primary "private Google" replacement — fully self-hosted, no tracking, fully customisable result weighting and source preferences, with API access for programmatic queries. SerpBear tracks keyword rankings across search engines for SEO teams who would otherwise pay for Ahrefs or SEMrush rank-tracking add-ons.

Common setups: a 12-person research team running SearXNG as their default browser search engine to keep query history off Google's logs and Bing's logs; a privacy-conscious household using SearXNG as the home network's default search across all devices; an SEO agency running SerpBear to track 500 keywords across 8 client sites with daily ranking snapshots, replacing the rank-tracking module of a $500-per-month all-in-one tool; a content team running SerpBear to monitor brand keyword positions and competitor SERP movements weekly. Both apps include API access and full data export. The category is genuinely thin — most teams need either a chat-based AI search (handled in the AI category) or full SEO research (Ahrefs, SEMrush, Moz remain the heavyweight options for the rest of the surface).

Build BI dashboards from your data

From €9 /app/month 

The trigger:The team's data is in Postgres, the dashboards are in Looker, and the per-seat cost has crossed €200 per month — most of which is paid so the marketing team can refresh a single chart twice a week.

BI software in this category covers self-serve analytics dashboards, ad-hoc data exploration, scheduled reports, and the link-archiving and rank-tracking layers that complement them. Metabase is the catalog's most popular choice — clean visual interface, native database connections (Postgres, MySQL, BigQuery, Snowflake, ClickHouse, Redshift, MongoDB), question-based dashboards, scheduled email reports, embeddable charts. Apache Superset is the heavier alternative for teams that want SQL-driven dashboards with more visualization options and a richer permission model. Linkwarden archives links and bookmarks with full-text search across snapshots — useful for research-heavy BI workflows where source-tracking matters. SerpBear extends rank-tracking BI for SEO use cases.

Common setups: a 20-person SaaS team running Metabase connected to the production Postgres replica with role-based access — sales sees revenue dashboards, product sees usage funnels, none of them see PII; an agency running Superset as the dashboarding layer for 6 client analytics deployments with scheduled weekly PDF reports auto-emailed to clients; a research team using Linkwarden to archive 5,000 source links with searchable snapshots; an e-commerce team running Metabase against the order database for daily revenue tracking and weekly cohort analysis. Database connections, dashboard exports (PNG, PDF, CSV), and SQL query history are part of the dashboard. SSO via Keycloak available across all four apps.

Take notes and build a second brain

From €9 /app/month 

The trigger:Notion's renewal climbs past €15 per user per month and the team uses 30% of the surface — or a privacy-conscious researcher needs encrypted note-storage that doesn't sit on a US-based provider's servers by default.

Note-taking software in this category covers task management with notes (Vikunja), encrypted real-time collaboration (CryptPad), markdown-first collaborative documents (HedgeDoc, Etherpad), personal knowledge management (Trilium Notes, Memos, Meemo), structured wikis (MediaWiki, Documize), the personal-CRM angle (Monica HQ), and collaborative whiteboarding (WBO). Trilium Notes is the catalog's primary personal-KM tool — hierarchical notes, cross-references, scripting, full export, attachment support, and a full-text search that handles thousands of notes. CryptPad handles end-to-end encrypted collaborative documents for sensitive notes. HedgeDoc runs the collaborative-markdown shape ideal for engineering team docs and meeting notes. Memos and Meemo handle the lightweight Twitter-style microblog or daily-journal use case for personal writing-practice.

Common setups: a software developer using Trilium Notes as a second-brain with cross-document linking, code snippets, and project notes — a single instance replacing Notion, Roam, and a paid Obsidian Sync subscription; an internal sec-ops team running CryptPad for incident-response notes that need encryption-at-the-document-level; a freelance writer using Memos for daily writing-practice short posts and Vikunja for pitching pipelines; a consultancy using HedgeDoc for collaborative meeting notes with markdown export to client deliverables. Note data, attachments, and revision history export in standard markdown or platform-specific formats. Migrate from Notion via the standard markdown export, or from Evernote via ENEX import.

Run a backend without writing one

From €9 /app/month 

The trigger:Firebase's per-read pricing makes the prototype's invoice 3× the projected unit economics at the first traffic spike — or Supabase's free-tier limits hit just as the side project stops being a side project.

Backend-as-a-service software in this category gives mobile and web developers an instant backend without writing server code: authentication, database, file storage, and real-time subscriptions. PocketBase is the catalog's lightest option — single binary, SQLite-backed, full auth and storage and realtime, ideal for small-to-medium apps that don't need the operational complexity of a full Postgres deployment. Directus runs the headless-CMS angle on top of any SQL database — REST and GraphQL APIs auto-generated from the schema, full role-based access, file management built in. Together they cover the spectrum from "I have a side project that needs auth and a database" to "I have a content platform that needs a custom backend serving multiple frontends."

Common setups: an indie developer running 4 side projects on a single PocketBase instance, each with isolated databases and per-app auth — total cost €9 per month replacing 4 separate Firebase projects; a content team using Directus as the headless CMS for a website, an iOS app, and a digital signage system — single source of truth across three frontends; a small SaaS using PocketBase as the backend for an MVP, with full migration path to Postgres or Directus when traffic justifies it; a freelance developer building client mobile apps on PocketBase with white-labelled admin dashboards. Database access, schema versioning, and full data export are part of the dashboard. Self-hosting means no vendor lock-in for auth flows, no per-read pricing, and no surprise quotas.

Monitor uptime, servers, and apps

From €9 /app/month 

The trigger:Datadog's per-host pricing crosses €500 per month and 80% of the value is the uptime check the team built itself — or a small SaaS realizes the observability tier costs more than the production servers it watches.

Monitoring software in this category covers uptime monitoring, server and application metrics, log aggregation, change detection, and the more specialized monitoring needs (network ad-blocking, EV charging, device tracking). Uptime Kuma is the catalog's primary uptime monitor — clean dashboard, multiple notification channels (Slack, email, Telegram, Pushover, Discord, Mattermost, Teams), public or private status pages, support for HTTPS, ping, port, and DNS checks. Grafana plus Prometheus plus Alertmanager is the metrics-and-alerting stack used by most production engineering teams. Beszel runs lightweight server health monitoring without the Prometheus operational overhead. ChangeDetection watches web pages for changes and alerts on diffs. AdGuard Home runs network-level DNS-based ad and tracker blocking. FindMyDeviceServer covers device location tracking. Linkwarden, Kimai, and Evcc round out adjacent monitoring shapes.

Common setups: a 5-person SaaS team running Uptime Kuma for public status, Grafana plus Prometheus for application metrics, and AdGuard Home for the office network — full operational visibility for €27 per month total; an internal IT team running Beszel across 30 servers with Slack alerts on anomalies and 90-day metric retention; a privacy-conscious family using AdGuard Home for network-wide tracker blocking across all devices; a content marketer using ChangeDetection to watch competitor pricing pages and product launches.

Centralize identity and remote access

From €9 /app/month 

The trigger:The team's mix of contractors, employees, and freelancers each need scoped access to internal systems — and a per-user VPN seat or per-user Okta licence for each one isn't sustainable at the current rate of project starts and finishes.

Network and infrastructure software in this category covers single sign-on, browser-based remote access, and DNS-level filtering. Keycloak is the catalog's primary identity-provider — SAML, OIDC, multi-tenant realms, social-login integration, fine-grained role-based access, fully featured admin console. Apache Guacamole gives browser-based RDP, SSH, VNC, and Telnet access without VPN client installation per user — ideal for granting time-limited access to internal hosts to contractors, offshore teams, or auditors who only need access for a single engagement. AdGuard Home runs network-wide DNS filtering for ad-blocking, tracker-blocking, and parental controls across every device on the network from a single configuration.

Common setups: an SMB running Keycloak as the SSO layer in front of the wiki, project management, password manager, support inbox, and email — one credential, one MFA setup, full audit trail across all internal apps; a managed services provider using Guacamole to give technicians scoped browser-based access to client-server hosts without distributing private SSH keys; a small office running AdGuard Home as the network DNS resolver to block ads and trackers across 15 devices without per-device installs; a 50-person remote company running Keycloak as the central identity layer with social-login fallbacks for contractors and SAML-only for employees. User directories, access logs, and policy exports are part of the dashboard. SCIM-based user provisioning available with Keycloak.

FAQ

Frequently asked questions

Each app you run costs €9 per month, regardless of how many people use it. A 50-person team running Vaultwarden pays the same €9 as a 5-person team running Vaultwarden. Run two apps, pay €18. Run ten apps, pay €90. Storage scales separately at €0.50 per GB per month above the bundled allowance.

This pricing was chosen specifically because it's the model SaaS competitors don't offer — flat per-app, not per-seat.
Most teams replace 2–4 categories at a time, not all 30 at once. The 30 categories above show the full surface — typical customers use it as a menu, not a checklist. A common starting point is the highest-cost tool — the CRM, the password manager, the analytics line item.

The open-source apps in each category are not feature-for-feature identical to the SaaS they replace. Most cover 80–95% of the surface that 80–95% of users actually use, at a fraction of the cost. Try a 7-day free trial to verify fit for your specific workflow.
Operating-system patches, application updates, TLS certificates, daily off-site backups, 24/7 monitoring with alerting, SMTP relay configuration, DNS management for the subdomain, daily security scans, and human support with a median first-reply under 4 hours.

What's not included: theming and customisation work, custom plugin development, data migration from other providers (some imports are documented and self-serve; complex migrations can be quoted separately).
You pick. 21 datacenter regions across six continents — Germany, France, Netherlands, Finland, UK, US (multiple), Canada, Singapore, Japan, Australia, Brazil, South Africa, and more. Each app runs in the region you choose at signup, and you can move regions later without re-platforming.
The full subprocessor list is published on the this page.
You can export everything from the dashboard at any time, in standard formats (the formats the open-source app itself uses — typically SQL dumps, ZIP archives, or platform-specific exports). No exit fees. No extraction projects. No proprietary lock-in.

Because the underlying software is open-source, you can also deploy it yourself or with another provider after exporting — your data is portable to anywhere the same application runs. The open-source license is the contract you can rely on, not a vendor's terms-of-service page.
Possibly. The 150+ apps in the catalog were chosen because they're broadly stable, have active maintenance, and cover real jobs-to-be-done. New apps get added regularly based on customer requests.

Email with the app name and use case. If the app is reasonably mature open-source software, it can usually be added to the catalog within 2–4 weeks. There's no extra charge for catalog additions.
A VPS costs less in raw infrastructure terms (€5–€20 per month for the hardware), but you take on the operational work: OS patching, application updates, backup setup and verification, TLS certificate renewal, SMTP configuration, DNS, monitoring, on-call response.

For most teams, the operational time required to run one self-hosted app properly is 4–10 hours per month per app. At any reasonable hourly rate, the math doesn't favor self-hosting unless the team has dedicated platform engineers with spare capacity. DANIAN is the middle path — you keep the data ownership and customisation of self-hosting, without the operational tax.
Yes. Sign up, pick an app, deploy. Seven days to evaluate. No credit card requested at signup. If you don't continue, the instance is deleted.

If you want to extend the trial — to involve more team members, run a longer pilot, or evaluate against a specific migration plan — email and we'll usually accommodate.
