I've needed thing like this a few month back and stumbled upon https://mock.codes/ which does the job too

I currently run this! Kinda... I haven't really touched it since 2017 when I built it as an evening project to see if it could be done as a static AWS API Gateway configuration. It costs a few dollars a month plus the domain cost and a fair amount of people use it so I've kept it up and running.

I've been meaning on writing the same functionality as an actual application and adding things like custom response timers, timeouts and more and deploying it to fly.io to try their service out but I haven't gotten around to doing it yet.

Cool! I think there's a lot of neat stuff that could be added here. Funny how a little event project can be so useful!

If you have any requests I'm happy to try to to implement them!

The biggest thing for me was that I needed to use subdomains. I needed to test a dependency that let the consumer pass in a domain, but no path. Subdomains fit the bill for that. It's the only thing I can think of offhand :-)

If you'd like, feel free to email me at contact@responsecodes.xyz and we can collab

How much would you save if you ran this on Cloudflare Workers?

I'm not really looking at it from a cost savings perspective since the operational cost is so low that even an hour of work covers paying for multiple years of it running. It really boils down to what different platforms I want to try out but you're right that Cloudflare Workers is another one to consider.

This is slick - thanks for sharing! I like how they list what the response codes are for

Adding a clicky link https://responsecodes.xyz, and for a 200 https://200.responsecodes.xyz

I actually encountered the same issue. I knew there was some service doing that, but I couldn't find it using Google. It took me several minutes.

I guess you have and edge if you manage to match user intent with your keywords and get ranked by Google.

Good luck!

This is the service I was trying to find but couldn't remember, thanks

There's ways to test software without having to leave localhost.
