After a rather twisty journey we are overexcited to declare that Dendrite (the next-gen Golang homeserver from the core Matrix team) has officially entered beta!! 🎉 Don't trust it with your data yet, but please spin up an instance & help us hunt the bugs! https://matrix.org/blog/2020/10/08/dendrite-is-entering-beta
Server run by the main developers of the project 
It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
