Hello, I would like to hear your opinions about a good selfhosted messenger like discord.

To list exactly what I mean by that is:

• No need for federation ( only will be used by friends )
• E2EE
• Support for direct messages
• Support for discord like server management by which I mean the ability to set rooms and topics for such rooms.

From what I know, this seems to be more similar to slack alternative’s but wanted to hear opinions of others.

I have been thinking about either matrix, mattermost, rocket.chat or revolt chat.

I already have a XMPP server, but setting up encryption and client’s has turned away quite a few people I would like to get onto this platform.

EDIT: As pointed by other people E2EE isn’t needed for my usecase if no federation.
