I didn't realize nostr:nprofile1qqsfev65tsmfgrv69mux65x4c7504wgrzrxgnrzrgj70cnyz9l68hjsg7lwc9 had already done this just a few days ago, but today I built a NIP 86 relay manager application — you can give it a try at https://landlubber.coracle.social.

I hand-coded this one, but I also vibe-coded another version concurrently to compare experiences and outcomes. Impressive as mkstacks is, the hand-made one (with a little help from Claude) won the contest. Still, I think the comparison is instructive — there were definitely some things the vibe coded version did better.

If you're interested, you can see a video comparison here:
