On the Home Assistant and Jellyfin reddits you'll see tons of vibecoded dashboards and plugins people are putting together - and those are just the ones people are sharing.

I personally have been building a bunch of little personal apps for my home that aren't worth the effort of sharing - like a customized dashboard of the Trimet buses closest to my house. The cost to build the initial good-enough version was literally 5 minutes plus another 10 to test and deploy.
