Hello! Just wrote a small program that responds to HTTP requests with the status you provide in the path.
https://genbyte.dev/status/302 returns Status 302
https://genbyte.dev/status/500 returns Status 500
The body of the HTTP response is the status code, too. I created this to debug a script that would have to wget a lot, and I didn't want to annoy someone's server.
I wrote a messy readme and put it up on sr.ht. You can find it here:
