My project for the past few years is called AppDeck, collection of self-contained HTML files that know how to save themselves back to the AppDeck server, which is just WebDAV. AI has been enormously helpful in building out a suite of apps that can do this. So far I have a diagram editor that can produce SVGs, a multi-document editor that backs everything with markdown, but supports Kandan boards, documents, logs, and calendars. I also have a work flowy clone that I've really been enjoying organizing ideas with at work. There's a gallery app that inlines all of the images and can display them full screen in a light box and with a timed slideshow that also supports captions and encryption.

All of it just runs out of a folder on disk and can either be deployed locally or on a server behind a login. I intend to open source it, but I'm not quite proud enough yet of some of the implementation aspects to do so. Hope to do it this summer though!

You can play around in the guestbook. I'm in it right now and you can see me editing things.

Cloudflare Durable Objects are pretty cheap and I'm using it like a very basic pub/sub with each deck having it's own DO. I did some calculations and it should be well within my spend limits.
