Lopecode: Self-editing, humanely embeddable Observable notebooks

Tool by Tom Larkworthy (2025)

Announced by Chris Shank in this Bluesky posting

The hermetic, self-hosted, self-sustainable, recursively exportable, offline-first, file-first, web-based reactive open-source programming substrate built on observable runtime is online finally!

The editing experience is not there yet. Probably wiser to fork the original Observable notebook if you seriously want to create a webpage.

Exciting environment that contains many things I want - self-hosted self-editing, reactivity and internal module resolution.
