I am. I've been working on it for 3.5 years. It's open source and it's called Comment Castles [0]. I am currently in the process of changing the name to Comment Castles, the main instance is currently at the old name [1].
All the features work with front-end JavaScript turned off.
I am currently wrapping up the OAuth 2 server implementation so that we can have third party apps (no API fees!).
After I wrap up some remaining features I am going to move everything to commentcastles.org and forward the old site there.
It's currently text only (emojis allowed).
I do want to build good custom search but haven't really started on that task yet.
skip the search engine for now. offload that to site:domain.com "search" on google. focus on your niche and delegate where you can. if you can't see why I am saying this, then you need somebody to help you prioritize cause search is not it when you can delegate it to google in less than a day.
