mitmproxy for Mac

Summary

mitmproxy is a free, open-source HTTP/S interception utility for macOS that lets you capture, alter, replay, and store web traffic. It’s built for people who need a hands-on way to inspect requests and responses — particularly developers and security analysts — and is useful for debugging, testing, and protocol analysis.

Primary capabilities

• Save complete traffic recordings so you can analyze sessions later or share them with teammates.
• Modify requests and responses as they traverse the network to test how applications react under different inputs.
• Monitor HTTP and HTTPS streams in real time with interactive inspection tools to see exactly what an app sends and receives.

How it helps teams

mitmproxy’s interface and toolset make it straightforward to examine and manipulate the data that flows through your applications. Whether you need quick ad-hoc debugging or to build complex test scenarios, it supports workflows ranging from simple inspection to scripted automation. That flexibility makes it a practical addition to any toolkit for working on web applications and APIs.

Suggested alternative

EasyOnTheEyes (Free) — a lighter option for users who prefer a simpler, more visually focused interface. It’s a good choice if you want basic interception and viewing features without the steeper learning curve of more feature-rich tools.
