BigBlueButton

I like its stability, the very useful features provided for e-learning or product demonstration.

Professional grade application. Runs in Windows, Linux, Firefox, Chromium, Chrome

Great feature set, like Zoom, but open source, and performs much better than Jitsi

Open source, privacy friendly solution. Not need to install on computer. Screen sharing work fluently.

Works mostly fine, best free tool and very good Zoom Alternative (Some PC / Laptop Mics still have problems, it is thesame with JItsi)
