Debugging
http-echo: a verbose HTTP echo server for debugging anything
A small Go HTTP server that prints every detail of an incoming request — handy for proxies, webhooks, and Kubernetes networking puzzles
Every few months I find myself stuck on the same kind of question: what exactly is hitting my service? A reverse proxy is mangling a header, a Kubernetes ingress is rewriting a path, a webhook provider is sending a body in some shape I didn’t expect. The fastest way to answer is to point the traffic at something that will tell me, in painful detail, what arrived.
That’s why I wrote http-echo: a tiny Go server that responds to any HTTP request by dumping a structured, human-readable report of everything it saw.
