## What it is
BigBlueButton is an open-source web conferencing system purpose-built for online learning, supporting real-time audio, video, slides with whiteboard annotations, chat, screen sharing, polling, breakout rooms, and session recording/playback. It runs on a dedicated Ubuntu 22.04 server and integrates natively with major LMS platforms like Moodle, Canvas, Sakai, and Open edX.

## Use cases
- host online classes with audio, video, and shared whiteboard
- run one-to-one online tutoring sessions
- create breakout rooms for group collaboration
- record and share lectures for later playback
- integrate a virtual classroom into Moodle or Canvas
- poll students and track engagement with learning analytics
- self-host a video conferencing server for webinars

## When to choose
- you need a self-hosted, open-source alternative to Zoom or Teams for education
- you want deep LMS integration (Moodle, Canvas, Sakai, Open edX)
- teaching features like multi-user whiteboards, polling, and breakout rooms matter
- you need session recording and playback built in

## When to avoid
- you need a lightweight meeting tool without a dedicated server
- you cannot provide a dedicated Ubuntu 22.04 server with 16GB RAM and 8 cores
- you only need simple peer-to-peer video calls
- you want a fully managed SaaS with no server administration
