Oh don't know yet. I built a recipe website as a project in my coding bootcamp several months back and while I was looking for a free option to host it (I did eventually find a free option for the backend--for a long time all the free options I saw were for frontend only, once Heroku shifted to paid only) I remember at one point I wondered if I could do it with NOSTR instead of a database and just build a frontend that simply collects notes that have been tagged as recipes.

The workings of NOSTR are still totally foreign to me, though, so I quickly gave up that idea so I could get on with my project and finish the bootcamp.

But it remains this niggling half-formed idea in the back of my mind.
