Gor

Practical and easy-to-use software tool for testing HTTP applications and services.

HTTP debugging proxy built for the modern stack. Fluxzy captures, inspects and modifies HTTP/HTTPS traffic with full HTTP/2 support, native PCAP capture, and a YAML-based rule engine that works the same on your desktop and in your CI pipeline. Think of it as what Fiddler would look like if you designed it today knowing everything we know about TLS, streaming and automation. The core engine is open source (.NET), the desktop app is free with no feature gating for hobbyists. Runs on Windows, macOS and Linux. No subscription, no Electron.
