I was wondering just now why in the midst of all this remote working boom Jitsi Meet is seldom mention. Jitsi Meet has been absolutely stellar every time I've used it. Great interface, not bloated even when running in a browser with 10+ other people, plenty of options to manage conferences with many people (raise-your-hand button, selective muting/soloing, etc). Creating a chat is as easy as typing a name and hitting enter, no account needed! And getting somebody to join is as simple as clicking a link to meet.jitsi.net/yourchatroomname.

On top of that it's open source and end to end encrypted.
