Opened up the repo for my little side project from the last few weeks: Clipy (pronounce or capitalise it however you want). It’s a 100% client-side app for presenting (micro)Python problems to students requiring just a static web host. Problem authors can define feedback rules and create unit tests and students can do them, loaded up from a CORS-friendly host (like raw Github content). https://github.com/zarify/clipy Still a WIP, but I think it’s pretty neat so far.
