Hey, trying to set up an end to end encrypted group chat stack for some friends. What options are out there besides Matrix?

Just use Signal, it spun out of OTR anyway - https://en.wikipedia.org/wiki/Off-the-record_messaging
It’s not self hosted but would Bitchat fit the bill?
(Can you make chats that aren’t geographical?)
Jitsi supports it - https://jitsi.org/e2ee-in-jitsi/
Signal
You can "self-host" Signal!?
Haven't tried it, but it seems so: https://github.com/signalapp/Signal-Server
You probably have to rebuild the clients though to have it use a custom server.
