We mostly use discord since it’s difficult to convince people to sign up for new services… Have to do a workaround to stream desktop audio on Linux, since their client still only supports that for Windows, but other than that it usually works.

Tried https://twoseven.xyz/ a few times during a period when Discord streaming was lagging a lot. It supports desktop streaming with a browser plugin, and sync watching on various streaming services. As far as I can remember it worked ok but had a few issues, though that was a while ago so those might’ve been fixed.

Also tried to get https://sfu.mirotalk.com/ working but for some reason video wouldn’t show up…
