## The Hook

mitmproxy sits between a client and the internet so you can inspect, modify and replay HTTP/1, HTTP/2 and WebSocket traffic, including TLS, from a console UI, a web UI or a scriptable CLI.

## What's Good

MIT (mitmproxy/mitmproxy), release v12.2.3 (2026-05-12), developed since 2010. Three front ends: mitmproxy (console), mitmweb (browser) and mitmdump (tcpdump for HTTP). Python addons let you rewrite traffic programmatically. Great for debugging mobile apps, API clients and agents. ★~45.7k.

## The Catch

You have to install and trust its CA certificate on the device, and apps that pin certificates won't work without extra steps. The last release was in May, though commits continue. Use it only on traffic you are allowed to inspect.

## Verdict

The standard open-source tool for seeing exactly what an app sends.
