Ask HN: What options do I have for self-hosted end to end encrypted group chat?

Maybe Jami, haven't looked at it for a while: https://jami.net/

i'm working on something now https://qrypt.chat

It's throwing a Railway error for me

fixin gnow

It’s not self hosted but would Bitchat fit the bill?

(Can you make chats that aren’t geographical?)

Signal

You can "self-host" Signal!?

You probably have to rebuild the clients though to have it use a custom server.

Jabber/xmpp

Delta-chat? Email based.
