Summary

mitmproxy is a free set of tools for inspecting and changing HTTP/1, HTTP/2, WebSocket, and SSL/TLS traffic as it passes through a proxy. It can intercept HTTP and HTTPS requests and responses for editing, save conversations for later analysis, and replay client requests or recorded server responses. Users can choose an interactive console, a browser-based GUI, or non-interactive terminal output through mitmproxy, mitmweb, and mitmdump. Proxy modes include regular, local capture, WireGuard, reverse, transparent, TUN, upstream, SOCKS5, and DNS. Python addons can respond to events, change proxy behavior, and expose commands. WireGuard mode can capture traffic from external devices or individual Android apps. The tool includes a certificate authority that creates interception certificates as needed. Installation options include Windows, macOS, Linux, PyPI, and official Docker images. The project says it does not phone home or check for updates. Documentation notes that HTTP/3 client replay is currently broken and that dependencies in precompiled binaries and Docker images are frozen at release rather than updated in place.

Who it is for

mitmproxy suits developers and other technical users who need to inspect, edit, record, or replay proxied traffic. Its Python addons may also suit users who want to customize proxy behavior.

What is good

Edits intercepted HTTP and HTTPS requests and responses
Saves conversations and replays traffic
Offers console, browser, and terminal interfaces
WireGuard mode can capture Android app traffic
Python addons can customize proxy behavior

What to know first

HTTP/3 client replay is currently broken
Bundled dependencies cannot be updated in place
Documentation directs support questions to GitHub

Verdict

mitmproxy offers several interfaces and proxy modes for working with HTTP and related traffic. Before choosing precompiled binaries or Docker images, consider their frozen dependencies and the documented HTTP/3 replay limitation.
