There’s three servers I know and like 10 clients.

Not sure when you last looked at the landscape.

Servers: Synapse, dendrite, conduit

Clients: (just off the top of my head)

Element, fluffychat, cinny, neochat, cyphon, nheko, schildichat

I love Matrix but they do have a bit of a monoculture problem which I hope will get better when the protocol stabilizes. As long as they document their standards we should be fine. Their big commercialization push could turn out to be problematic in the long run, but we have to give them the benefit of the doubt and see.

If you want all the voip bits in place and all the latest features, you have to run a specific combination of synapse, sliding-proxy and element as the client. The xmpp ecosystem has similar problems but it gives a bit more leeway with various combinations of servers and clients that work well.

Matrix has more focus on IRC-like rooms, has a lot more features for that purpose and is much nicer to use than any conference xmpp extension.

Apart from Synapse, server implementations are stuck in permanent beta.

Clients outside mobile OSes are not interesting if you are considering Signal replacements. On mobile, you have element and maybe fluffychat.

It is still a messaging thingie that lacks a decent server implementation, and lacks a good client app.

Current EU politics motivate some to develop more. Where is oppression, there is reaction.
