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.
