BigBlueButton is an open source web conferencing system for on-line learning.
We believe that every student with a web browser should have access to a high-quality on-line learning experience
We intend to make that possible with BigBlueButton.
The BigBlueButton project is supported by a community of developers that care about good design and a streamlined user experience.
See API examples for how to integrate BigBlueButton with your project.

Record and Playback
BigBlueButton can record your sessions for later playback by students.
The whiteboard controls let you annotate key parts of your presentation.
You can broadcast your desktop for all users to see (requires lastest version of Java for presenter only).
Users of Chrome and FireFox browsers will benefit from high-quality, low-latency WebRTC audio. (Users of other browsers will seamlessly use Flash-based audio.)
You can upload any PDF presentation or MS office document. BigBlueButton keeps everyone in sync with your current slide, zoom, pan, annotations, and mouse pointer.
Multiple users can share their webcam at the same time. There is no built-in limit on the number of simultaneously active webcams.
Students can raise hand and use emoji icons for feedback.
You can poll students anytime to increase engagement.
You can interact with students through public and private chat.
You can enter live captions for students. These captions will later appear as subtitles in recordings.
You can group and place students into breakout rooms (full BigBlueButton sessions) for give number of minutes for increased collaboration.
Students with visual disabilities can use JAWS screen reader to interact with BigBlueButton.
