httpcat

Small CLI utility for hand-constructing raw HTTP requests, for low-level debugging.

Desktopfree

httpcat is a small, free command-line utility for hand-constructing raw HTTP requests, useful for debugging server issues, testing how a server handles malformed requests, or learning HTTP at the protocol level. It automatically completes line endings and defaults so requests can be piped into a tool like netcat. It's a niche complement to full HTTP clients like curl or HTTPie.
