This is really amusing. Because absolutly eveyrone I know vibe-coded this thing. I think the first one was https://github.com/ralt/dns-to-port possibly mine is second (but it is very much a joke so I am not linking it) .. Vercel later did https://github.com/vercel-labs/portless and I would imagine quite a few others. Zeitgeist. Also this does probably mean its kinda useful.

And that none of us can get bothered to "Google" if a thing that does the same thing already exists. Currently vibing, on a train, a spaced repetition thing for my kid - because I needed a specific list of countries - and its faster to create the whole app rather than figure-out how to find one that would do this.
