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 OpenOffice), webcams, whiteboard, chat, voice over IP (using FreeSWITCH), and desktop. It can record and playback all content shared in a session. The BigBlueButton project is is supported by a community of developers that care about good design and a streamlined user experience.

The use cases for BigBlueButton are

  • One-to-one on-line tutoring
  • Small group collaboration
  • On-line classes (25 or less)

BigBlueButton is built on the shoulders of giants.
