Web Debugging Proxy that logs all HTTP(S) traffic for comprehensive analysis. It allows manipulation of traffic, supports scripting, and extends with .NET. Debugs virtually any application, implementing man-in-the-middle interception with self-signed certificates. Freeware, ideal for developers.
















































mitmproxy is the King of CLI. Debuggo is the Queen of GUI.
mitmproxy is an incredible open-source tool for power users who love the terminal and want to write Python scripts to manipulate traffic. It is lightweight and perfect for automation.
Debuggo (Chaos Proxy) builds on similar concepts but wraps them in a modern Cloud Dashboard. Instead of memorizing hotkeys and CLI commands, you get a visual interface to click-and-inject faults (500 errors, latency).
The Verdict: If you live in the terminal, stick with mitmproxy. If you need a visual tool for mobile development that allows sharing logs with a link, Debuggo is the better choice.
