Just ran across worm blossom, willow, and sneaker web, and I'm very intrigued.

A lot of what I've been using AI to build in the evenings are offline, capable, highly resilient, simple pieces of software for basic information sharing and online interaction, where I use the word online perhaps a bit loosely.
In particular, I'm putting the finishing touches on a tool called AppDeck, which can serve plain HTML files that are entirely self-contained applications from a directory on disk, and then make that available both on the local network and to local users for editing and update. I'm going to give sneakerweb in particular a much closer look because that seems to be highly relevant to my interests.
