@rek2 you left out #Jami, which has a much more consistent #UX across platforms than #Tox (eg none of the Tox mobile apps I've tried support group chat). You also left out #BigBlueButton, which I keep hearing is much less of a resource hog on the server-side than #JitsiMeet, and I can confirm JM is a massive resource hog on the client-side. I haven't used #Discord but I've heard #Riot (#Matrix client) is a pretty good substitute?
