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.

BigBlueButton supports real-time sharing of slides (PDF and any document readable by LibreOffice), webcams, whiteboard, chat, voice over IP (using FreeSWITCH), and desktop. It can record and playback all content shared in a session. The use cases for BigBlueButton are

  • One-to-one on-line tutoring
  • Small group collaboration
  • On-line classes (50 or less)

For more information on the latest release -- including installation instructions, demo server, API, and overview of architecture -- see
