HTTP Error Lookup Codes
Understand HTTP errors instantly; causes, comparisons, fixes
What it does
ErrorLookup helps developers quickly understand HTTP status codes while debugging APIs, servers, and web infrastructure. Instead of just definitions, ErrorLookup shows: • what each HTTP status code actually means • common production causes • related codes that developers often confuse • practical fixes for redirects, client errors, and server failures Built to be fast to scan during real debugging sessions, whether you're working on APIs, reverse proxies, load balancers, or web applications.

Hi, I created httpdbg, a tool for Python developers to easily debug HTTP(S) client requests in Python programs. I developed it because I needed a tool that could help me trace the HTTP requests sent by my tests back to the corresponding methods in our API client. The goal of this tool is to simplify the debugging process, so I designed it to be as simple as possible. It requires no external dependencies, no setup, no superuser privileges, and no code modifications. I'm sharing it with you today because I use it regularly, and it seems like others have found it useful too—so it might be…

When I came to test it, the remote site was working fine, but I still wanted the 502. So I created statuscoder, just append your desired status code to the URL and it'll respond with that code. http://statuscoder.com It's my first single-use project and I like its simplicity - it does one job and (hopefully) does it well. Is there anything else that you'd want to see it do?
