What is BigBlueButton?
BigBlueButton is an open-source video conferencing server built specifically for virtual classrooms rather than general-purpose meetings. It's maintained by Blindside Networks and licensed under LGPL-3.0, with full source on GitHub. Instead of a generic video-call feature set, BigBlueButton ships classroom tools: a multi-user whiteboard, document upload with slide annotation, breakout rooms, polling, hand-raise, shared notes, and AI-generated smart slides. It integrates directly into learning management systems including Moodle, Canvas, Sakai, D2L, Jenzabar, and Schoology, so instructors launch sessions from inside the LMS they already use. There is no BigBlueButton desktop or mobile app — it runs entirely in a browser. Self-hosting is free, but running it reliably (audio/video processing is CPU-intensive) requires either your own Linux server meeting BigBlueButton's hardware requirements or a paid commercial hosting provider such as those listed at bigbluebutton.com.
BigBlueButton is an open-source web conferencing platform built for online teaching rather than general business meetings, maintained by Blindside Networks and integrated directly into Moodle, Canvas, Sakai, D2L, Jenzabar, and Schoology. It is free to download and self-host under the LGPL-3.0 license, with full source at github.com/bigbluebutton/bigbluebutton; commercial hosted and supported versions are sold separately by third-party providers through bigbluebutton.com. The platform runs entirely in the browser with no desktop or mobile app, and includes a multi-user whiteboard, breakout rooms, polling, shared notes, and AI-generated "smart slides" for uploaded documents. Because BigBlueButton is self-hosted server software rather than a managed SaaS, teams without in-house server infrastructure need a commercial hosting provider to run it reliably at scale.
Standout feature: Deep integration into Moodle, Canvas, Sakai, D2L, and Schoology lets instructors launch a full virtual classroom — whiteboard, breakout rooms, polling — directly from inside the LMS they already teach in.
Biggest weakness: There is no first-party paid plan to simply sign up for: running BigBlueButton means self-hosting a resource-intensive Linux server yourself or shopping among third-party commercial hosts, since the core project doesn't sell or standardize hosted pricing.
Pros
- Free and open source under LGPL-3.0, with full source available on GitHub.
- Purpose-built classroom tools: multi-user whiteboard, breakout rooms, polling, shared notes, AI smart slides.
- Native integration with major LMS platforms (Moodle, Canvas, Sakai, D2L, Schoology).
- Runs entirely in the browser, no desktop or mobile client to install.
Cons
- Self-hosting requires a Linux server with real CPU/RAM headroom for video processing; underpowered servers cause dropped audio and video.
- No single official paid SaaS tier — commercial hosting pricing varies by third-party provider, not standardized.
- Built for classroom teaching, not general business meetings, so it lacks features common in tools like Zoom, such as advanced webinar registration.
