It is an more private alternative to Discord. Even tough they do not offer federation, self-hosting servers is possible, but self-hosting Dms is not possible. Matrix does not have separated voice and text chats in one server, aka Discord style. Is it better to use Revolt for now or create our own Federated Discord alternative?

It seems OK and the interface looks slick but I tried a few months ago and could not make it work following the documentation, I thought I would wait a little bit before trying again.
I think I read somewhere they would think about federation in a second time. That doesn’t bother me so much as I would probably use it like mumble with a small group of friends. That being said I do think federation would be a great feature to have, specially for the app adoption.
