Just a simple 20-minute project with Claude Code but one that I use every day for grocery shopping with my wife.

The interesting technical piece is that each list is a Cloudflare Durable Object that handles both the websocket as well as data storage via the now built-in SQLite dbs.

I love the Cloudflare stack generally but it really shines with little projects like this in that request and compute time is really cheap and almost everything scales to zero, so hosting doesn’t cost you anything for silly hobby projects like this (I think the only carrying cost will be be 20 cents per gigabyte-month for the tiny amounts of data saved).

I also created a skill for Claude Code for the Cloudflare stack and it seems to work really well. I think a set of relatively simple primitives like Cloudflare provides along with no or minimal external dependencies seems like ideal for today’s AI.

Thanks for letting me share :)
