We've been working on BigBlueButton, an open source web conferencing system for on-line learning, for over seven years. Our goal for the project is to provide remote students a high-quality online learning experience.
BigBlueButton enables real-time sharing of audio, video, slides, chat, desktop, polls, and emoji. It has deep integrations with other open source learning management systems such as Moodle and Canvas.
The project is hosted at
and the documentation (including steps to install) are here
We've been forked over 3,000 times on GitHub. If your looking for open source solutions for teaching your students on-line in a live synchronous classroom, we are building BigBlueButton for you.
Don't hesitate to post a follow-up if you have any questions about the project.
