I've originally started developing Mikoto as a Discord extension, but pivoted when I realized that it was against their TOS + there's only much you can do if you only have a partial control over the stack.
We're open source, at https://github.com/mikotoIO/mikoto. We also will have a very comprehensive extension API, powered through iframes + wasm "containers". We also focus our features on superusers, and will eventually seek monetization through selling integration and enterprise hosting.
Spent some time reading through matrix specification; my opinion is that it's overkill in some ways and under-delivers in some parts of its specs for my usecase, enough to justify writing a whole new protocol from scratch
With that being said, we're working on implementing a matrix compatibility layer!
