Lord Doctor Olle WA couple of years ago a colleague and I implemented a MVP of a Mikado tool. A web based Mikado graph that could be used by multiple people simultaneously.
It’s a bit rough around the edges but it mostly works. Written in pure Javascript, running on Vercel with Supabase as the backend.
