Besides the expensive Matrix option the parent suggested, IRC covers text fine. Mumble handles low-latency, low-resource voice chat with positional audio for games. XMPP uses more resources that IRC (but can have encryption) but a ton less resources than Matrix which makes it suitable for self-hosting—my partner & I do voice/video calls over my home server fine & Movim is working on group calls with a Web UI (tho it should be noted both Zoom & Jitsi use XMPP under the hood).

What do you need screen sharing for? This comes up so, so rarely for me.

it's convenient, also it'd be nice if it had the feature capability.

Mumble is great, but if there was something like mumble, that implemented video sharing, that would be miles better, though a lot of people would probably still use mumble, as it's fine.

From what i've dug into, basically every video sharing capable setup is based on web technology, and i simply refuse to go near web technology unless i WANT to use a web browser. It's just, worse, in so many ways.

Well Discord, Slack, & others are web tech too so it’s not like avoiding it is easy. If I have to use these services, I would prefer it be in the browser’s sandbox.

Even still, almost all debug, troubleshoot, pairing session I have done in the last 4 years have been done over Upterm or Tmate, which is much, much lighter on bandwidth & not crushed by video compression.
