Check out bigbluebutton [0]. It is open source with tons of features. It however requires specific Ubuntu 16.04 version and can only be installed on that OS. It is not the best fit for very large audiences (say over 200) in one session BUT for that they are working on another load balancing solution recently [1]

I have been using this for our clients (edtech) for a while and with their 2.2 official version, they made it HTML5 only and removed flash. Works really well if you follow all the guidelines and installation instructions.

They also have a bash installer script [2] which literally does everything for you in one single script.

I use it as a student. It's very good and easy to use. I'm curious about the performance with many participants though as we only use it in classes with at most 40 persons. And of course no camera just the presentation.

Do you have first hand experience with BBB?

[codegeek]

yes I have installed it, ran it, configured it and broken it many times :). Feel free to ask me anything.

Really enjoy BBB, we used as a replacement from Zoom when all the security stuff came out.
