My only complaint with self-hosting matrix is that the canonical python implementation is quite resource-heavy. I was unable to run it on a cheap VPS. I hope that the ecosystem will improve in the future.
I agree. I really prefer Dendrite, their Go server, but development has slowed down lately. Also, because of the financial issues they have been having, I don't have a lot of hope that Dendrite will get a lot of attention. Maybe Conduit(https://conduit.rs) will become more viable instead of Dendrite. We really need a small efficient build with no moving parts, for the self hosters community.
