Came across this on the r/selfhosted community. Still very much in the alpha stages, but it’s already got a Docker image you can try out for yourself, or try out the demo server.
Tried it earlier today, couldn’t get the voice/video chat to work right away on my self-hosted setup but the real-time chat was very snappy. Looks promising.
I’m in a Discord server with 2000 members. You really want to encrypt and decrypt all incoming and outgoing messages 2000 times? There’s a reason why most E2EE messaging apps don’t really do that for group chats.
