Free open source alternative to zoom

In the current environment of Lockdown and many people forced to work from home. Video chat is becoming one of the most in-demand software tools needed by any industry. Just found a gem. Jitsi is a video chat app between two people or 200. Whether you want to build your own massively multi-user video conference client, tools are 100% free, open-source, and WebRTC compatible.

PS: I am loving it.
