cinny VS ocaml-matrix

Revolt, Guilded, Element (Matrix Client), Matrix, Cinny (Matrix Client), Spacebar, Rocket Chat, Mikoto, Mattermost, Teamspeak and Nertivia

Check out these two clients: https://app.element.io https://cinny.in

or Cinny, given its country of origin... (https://cinny.in)

building on what the original comment said with the matrix mention, cinny.in is another option that is built with it if you wanna check it out! pretty similar layout to discord, already has encryption unlike revolt too

Specifically Cinny since it mimics the look and feel of Discord

Keep in mind Matrix is a protocol for messaging just like email is a protocol for mail. There's more than one client and Element just so happens to be the most popular one. A really good runner-up would be FluffyChat. Then there's Cinny

Matrix, is a decentralised messaging protocol. While it isn't a messenger in itself, it has various messaging clients such as Element, Cinny etc

Cinny, a matrix client that looks and behaves like discord

Cinny is potentially the best best Matrix client that resembles Discord

Other clients are available on the same network, like https://cinny.in/ or https://element.io

There are a few other server implementations (polyjuice in Elixir https://gitlab.com/polyjuice/polyjuice_server; https://github.com/clecat/ocaml-matrix in OCaml; the abandoned mxhsd in Java) - but the most stable ones alternatives to Synapse right now are Dendrite (Go) and Conduit (Rust).

Matrix's API surface is big, and servers deliberately handle all the heavy lifting in order to make clients trivial to write, so writing servers is not trivial. But Dendrite & Conduit are both very usable and making good progress right now.

And yes, the APIs are all standardised (while also constantly evolving) as per https://spec.matrix.org :)
