ABOUT THE SOFTWARE

What is Greenlight

Greenlight is the simple web front-end for BigBlueButton — the open-source virtual classroom used by universities, schools, and government training programs around the world. Teachers schedule rooms, students join through a single link, recordings publish back to the LMS.

The project is published under the LGPL-3.0 license and maintained by BigBlueButton Inc., the company behind BBB, with commercial support coming from Blindside Networks in Ottawa.

BBB scales meaningfully in production. France's national education platform Apps.education.fr is built on BigBlueButton and serves roughly 330,000 daily users by end of 2025, with the platform engineered for up to 40,000 concurrent users and a 500,000-user surge ceiling. Universität Osnabrück, TU Berlin, Humboldt-Universität, TH Mittelhessen, the French Ministry of Education, and the Brazilian National Research and Education Network are named in the BBB project's own publiccode.yml as known operators.

FEATURES

What Greenlight does

Greenlight is the room-management UI; BigBlueButton is the conferencing engine. Together they cover the full virtual-classroom surface that proprietary education SaaS charges per-host for, with the recordings landing on a disk you own.

Multi-user whiteboard

tldraw v2 powers the in-meeting whiteboard. Annotation over slides, freehand, shapes, text. Every participant draws on the same canvas in real time.

Polls and Quiz

Anonymous or attributed polls during a session. BBB 3.0.11 added a built-in Quiz feature with results captured in the Learning Analytics Dashboard.

Shared notes

BlockNote-powered shared notes in BBB 3.0. Live collaborative note-taking saved with the meeting record. Exportable as PDF or plain text.

LMS integration

Moodle 4.0 ships a built-in BBB activity. Canvas connects via LTI. Sakai, Blackboard, Schoology, Open edX integrations all supported.

Breakout rooms with timer

Split a session into up to 8 sub-rooms. Countdown timer announces return to the main room. Moderators can drop into any breakout to listen.

Server-side recording

Recordings reconstruct the full session — slides, video, chat, whiteboard, polls. Native playback is an HTML5 bundle. MP4 export available on request.

Screen sharing and slide annotation

Presenter shares screen or uploads slides — PDF, PPTX, DOCX, ODT, images. Annotation tools work on uploaded slides without leaving the meeting.

OpenID Connect SSO

Native OIDC in Greenlight v3. SAML and LDAP work by fronting Greenlight with Keycloak — shipped with the BBB installer as an optional component.

WHAT'S ALWAYS INCLUDED

Every app. Fully managed.
Nothing extra to pay for.

Every app you deploy includes the full managed service — security, backups, updates, and support from day one.

Automatic updates and patches

Apps run the latest stable version. Security patches applied silently, with rollback if needed.

Daily off-site backups

Multiple daily backups in redundant off-site locations. One-click restore if anything goes wrong.

24/7 uptime monitoring

Continuous monitoring with instant alerting. We respond before you notice.

SSL, firewall, DDoS protection

Auto-renewing SSL, hardened firewall rules, DDoS mitigation on every deployment.

Performance and scaling

We monitor resource usage continuously. When your app needs more headroom, we flag it and upgrade with your explicit approval.

Dedicated engineering support

Real engineers on chat. DNS, SMTP & migration help. All included in €9.

WHY MANAGED

Why teams pick managed Greenlight

In August 2023 a Zoom Terms-of-Service update granted the company rights to use customer audio, video, and chat to train AI — walked back partially after public backlash. The carve-out applies only to "Customer Content," and consent is granted by the account owner. For schools and universities, that is a problem that has not gone away.

Self-hosting BBB solves the trust problem and replaces a per-host bill with a flat one, but the day-two operational surface is real. The single most common failure mode in the BBB issue tracker is FreeSWITCH NAT configuration: WebRTC audio fails with error 1002 or 1007 even when video works, because FreeSWITCH advertises the server's internal IP rather than its public one. Issue #17134 on the BBB repo is the canonical write-up — the fix is editing /opt/freeswitch/conf/vars.xml and external.xml, and on a busy installation that's a 2 a.m. call.

The other day-two failure is Greenlight's open registration default. The v2 sample.env shipped with DEFAULT_REGISTRATION="open," meaning anyone with the URL could create an account and consume server resources. That was filed as issue #5162 in 2021 and is the kind of thing you find out you had wrong when the resource graph goes sideways during a Tuesday-morning class.

USE CASES

Three teams who run Greenlight on DANIAN

These are representative team types we set up most often. Each starts with the same flat €9 plan.

Mid-sized public university

Replacing Zoom Education after the AI-training ToS update

Germany region. 4-node BBB pool behind Scalelite, NFS-shared recordings, Keycloak federating the campus Shibboleth IdP into Greenlight via OpenID Connect. Moodle 4.x launches rooms over LTI; activity completion gated on attendance.

Vocational training provider

Audit-grade attendance recording for an AZAV-audited program

UK region. Recording-on default, 24-month retention, Learning Analytics Dashboard CSV exported nightly for the auditor's record, MP4 export enabled for the certifying body's evidence pack. Single BBB node, ~120 concurrent across two cohorts.

Online tutoring platform

Per-tutor rooms with parental safeguarding turned on by default

Canada region. Greenlight "Approve/Decline" registration, viewer cameras off, private chat disabled at room level, recording mandatory and retained 30 days for safeguarding review. 18 tutors, peak 80 concurrent students.

COMPARISON

Four ways to run Greenlight

The choice is rarely Zoom-or-build. It's between four real paths, each with a different cost shape and a different operational debt. Below is what the line items look like at 1, 5, and 10 hosts — and what each path costs in time, not just money.

Zoom pricing is the Workplace Pro tier as published at zoom.us/pricing (annual billing). DANIAN's €9/month is the platform-wide flat rate — it does not scale per host or per session.

BY INDUSTRY

Greenlight for specific industries

A virtual classroom in higher ed is not the same surface as one in vocational training or one in a government agency. The compliance shape, the cohort size, and the recording-retention policy diverge — these are the four industries where the BBB+Greenlight fit is sharpest.

Universities in the US sit under FERPA (20 U.S.C. § 1232g) for student educational records; non-US institutions under regional data-protection regulation and Schrems II constraints on US-resident SaaS. Both regimes are easier to reason about when the recording disk and the meeting server are in a region the institution chose.

On DANIAN we run each university tenant in an isolated container, federate the campus Shibboleth IdP through Keycloak into Greenlight v3 over OpenID Connect, and pin the recording region. Room launches come from Moodle, Canvas, or Sakai over LTI 1.3; recording publishes back into the course activity automatically; activity-completion gates on attendance threshold.

Sizing reference: BigBlueButton recommends keeping individual meetings to 100 participants or fewer for stable interaction, and a single reference-configured BBB server handles around 200 concurrent users across multiple rooms. Scalelite layers in behind that line.
K-12 deployments need to satisfy COPPA for under-13 students in the US and equivalent rules at the state level — California SOPIPA, New York Education Law 2-d, Illinois SOPPA — plus international parallels. Most of these statutes care less about which vendor you use and more about what defaults the children join under.

The DANIAN defaults for K-12 set Greenlight registration to Approve/Decline, viewer cameras off, private chat disabled, and recording off unless a safeguarding policy explicitly requires it. Teachers schedule classes inside the LMS; students join through their school identity; breakout rooms split a class for small-group reading or maths.

The free Moodle BigBlueButton tier caps classes at 25 users and 60 minutes — a useful sizing reference for what "free" gets you in this segment. A managed BBB server lifts both ceilings; what stays unchanged is that the recording, the chat transcript, and the shared notes live on a disk the school controls.
Accrediting bodies — IACET CEUs and NCCRS in the US, OFQUAL in the UK, AZAV for Bildungsträger in Germany, ISO 9001 training-record clauses globally — require auditable attendance and retention. The artefact the auditor wants is the cohort-attended-the-session record plus the session itself, retained for the policy window.

We turn recording on by default, set retention to 24 months, and enable the Learning Analytics Dashboard so the CSV export captures attendance, raise-hand events, poll responses, and the built-in Quiz results that shipped in BBB 3.0.11. The MP4 export job runs nightly; the archive is what the auditor sees.

Capacity planning is concrete here: native BBB recordings run around 150 MB per hour at 720p, which sets the storage shape for the retention window. A 40-hour cohort at weekly cadence over a year produces roughly 6 GB per learning track — small enough that off-site backup is cheap.
Public-sector buyers face national sovereignty rules and Schrems II constraints on US-resident SaaS. The Data Privacy Framework was upheld at the General Court in September 2025 but is now on appeal at the CJEU (Case C-703/25 P); the US PCLOB lost quorum in January 2025. The legal ground is moving, and procurement teams notice.

For government tenants we run Greenlight in a sovereign region of the customer's choice with no third-party telemetry, a dedicated TURN server on a public IP, full disk encryption, and short log retention (90 days maximum). Identity federates through the agency IdP; recordings land in agency-managed object storage.

The operational reference shape is France's national platform Apps.education.fr — built on BigBlueButton, engineered for 40,000 concurrent users, surge-able to 500,000, serving roughly 330,000 daily users at the end of 2025. The architecture proves the scale; the managed offering brings the same pattern down to a single agency's size.

FAQ

Frequently asked questions

Everything teams ask before signing up — answered straight, without sales speak.

Three groups: technical setup, migration, and how DANIAN works as a service.

01

Technical and configuration

A reference-configuration BBB server handles around 200 concurrent users across all rooms. The project recommends keeping any single meeting to 100 participants or fewer for stable interaction.
Greenlight v3 supports OpenID Connect natively. SAML and LDAP work by fronting Greenlight with Keycloak, which the BBB installer ships optionally. The project does not plan to add native SAML — the maintainers state that OIDC providers should be used to bridge SAML upstream. We wire the OPENID_CONNECT_* environment variables on your behalf during setup, and federate against your campus IdP.
Moodle 4.0 and later ship a built-in BigBlueButton activity module — no plugin install. Canvas connects through the BBB LTI app in the Canvas App Center. Sakai uses the BigBlueButton Sakai tool. Blackboard works through the BBB Building Block. We provide the LTI key and secret, you paste them into the LMS once, and rooms appear as course activities afterwards.
Greenlight v3 is a full rewrite. Rails 7 with a React front-end replaced the older v2 stack. PostgreSQL is the only supported database now. The deployment model is Docker-compose. Authentication is OpenID Connect — no native SAML. The migration tool ships under bin/rake — migrations:roles, users, rooms, and settings — and recordings stay on the BBB server unchanged across the upgrade.
No. Transport between browser and server is encrypted (TLS for control, DTLS-SRTP for media), but the BBB server processes audio, video, and chat in cleartext because mixing, recording, and the live HTML5 client experience require it. If your compliance team needs true end-to-end encryption on every media leg, BBB is not the right tool — you want a peer-to-peer system. The E2EE feature request is tracked upstream as issue #9893 with no firm ETA.
All four ship. Breakout rooms split a session into up to 8 sub-rooms with a countdown timer. Polls are anonymous or named, multi-choice or response. The multi-user whiteboard is tldraw v2 — annotation on slides, freehand, shapes, text. Shared notes are BlockNote in BBB 3.0. BBB 3.0.11 added a built-in Quiz feature. BBB 3.0.19 added a Unified Layout that pins the presenter cam and screen-share side by side.
BBB runs entirely in the browser on iOS Safari and Android Chrome with the same UI. There is no separate native app to download. Receiving a shared screen, joining audio and video, raising hand, and using the whiteboard all work from a phone. Sharing your screen from a phone is the one feature that's not supported — that's a WebRTC limitation, not a BBB one.

02

Migration and onboarding

We can activate your app on your own custom domain/subdomain. Examples: mydomain.com, anyword.mydomain.com.
Or, on our randomized free subdomain. Example: 963.apps.danian.cloud
If you wish to use a custom domain/subdomain, select that option when ordering your app (or notify us later). We will send you the required DNS records and if needed, our tech team will modify them for you.
21 datacenter locations across six continents. You choose the region at provisioning. Application data sits in the region you choose; pick whichever is closest to your users or matches your data-residency preference.
Yes. Request a region migration from the dashboard and we run the move in the background. The system emails you when the migration completes; total transfer time depends on data volume but typical instances finish in a few hours. There is no extra charge for a region change.
Yes. Full data export is available at any time, in a portable format you can bring to any infrastructure.

03

Billing, support, and platform

€9 covers everything we do for that app: hardware in the region you choose, daily off-site backups with one-click restore, automatic security patches and version upgrades, 24/7 monitoring, SSL and firewall, and engineering support on Email/LiveChat. There are no setup fees or hidden line items. For more info see our Pricing page.
If you decide to continue, we charge €9/app/month from day 8. If you don't, the trial ends and you can export your data. No card is required for the trial, and we never auto-charge you without explicit consent.
No. The €9/month is flat regardless of how many users log into your app. Add 5 users or 50; the price doesn't change.
24/7 Live chat and email support, both staffed by engineers who run the systems. We handle DNS configuration, SMTP setup, app integrations, performance tuning, troubleshooting, and migration help. Response time is typically under an hour. There is no tier system — every customer gets the same support.
Yes. Cancel from the dashboard. We don't charge a cancellation fee, we don't lock data, and we will export your data to you on request before deletion. data to you on request before deletion.
Every customer instance is backed up daily to a separate region from the primary. We test restores. You can request a restore at any backup point within the retention window — usually 7 days for daily backups.
Your application data sits in the region you choose at provisioning — 21 datacenter locations across six continents. Account-level data (billing, account email, support ticket history) is processed centrally. Application data region is picked by you, per app.
99.9% uptime SLA on every app, every tenant. Service credits are documented at danian.co/service-level-agreement. The status page is located at status.danian.co.
When your tenant approaches the resource ceiling — the base tier holds 1 vCPU/RAM, 30 GB storage — we notify you. Resource upgrades happen with your explicit consent; we will not upgrade your tenant or charge you without it.
We wait. We don't suspend the app or delete your data on the first failed charge. We email you, you fix the card on file, and we continue.
Invoices can be downloaded from the billing dashboard in PDF the day each charge succeeds. EU VAT is added where applicable and the VAT-reverse-charge regime applies for VAT-registered businesses with a valid number.
