# BigBlueButton — An open-source video conferencing server built for virtual classrooms, with a multi-user whiteboard, breakout rooms, and LMS integration, free to self-host under LGPL-3.0.

> **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.

## Facts

- Pricing: Free (verified undefined NaN, NaN)
- License: Open source

- Best for: schools, universities, and training organizations that need LMS-integrated virtual classrooms and are willing to self-host or pay a commercial BigBlueButton hosting provider
