## What it is and what it does

mitmproxy-windows is a companion package to mitmproxy that provides precompiled Windows binaries needed for transparent traffic interception on Windows systems. It includes a Rust-based redirector executable that routes traffic through a Windows named pipe to mitmproxy, along with a vendored copy of WinDivert, the underlying library that performs the actual traffic redirection at the system level.

This package is primarily used by developers and security professionals who need to intercept and inspect HTTP/HTTPS traffic on Windows machines. It integrates directly with mitmproxy's local mode and handles the platform-specific mechanics of transparent proxying, which would otherwise require manual WinDivert setup. The package is actively maintained and has no known security vulnerabilities.

Use it for:

- Debugging HTTP/HTTPS requests from Windows applications by transparently intercepting traffic with mitmproxy.
- Testing web applications and APIs by capturing and modifying requests and responses in real time.
- Security research and penetration testing on Windows systems requiring transparent proxy interception.
- Monitoring and analyzing network traffic from curl or other command-line tools on Windows.
- Development and testing of mitmproxy itself on Windows platforms.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Windows-specific traffic redirection binaries for mitmproxy, enabling transparent HTTP/HTTPS interception on Windows via a named-pipe redirector and vendored WinDivert library.

Yes, if you are on Windows and need transparent HTTP/HTTPS interception with mitmproxy. The package is actively maintained, has low install friction, carries no known vulnerabilities, and provides essential Windows-specific binaries that mitmproxy cannot function without on that platform. Be aware of the LGPL-3.0-or-later copyleft license if you plan to redistribute or modify it, and ensure you have Python 3.12 or later.

## Install

pip install mitmproxy-windows
uv add mitmproxy-windows
poetry add mitmproxy-windows

## Installing mitmproxy-windows

Before you install: Low install friction with a pure Python wheel distribution. Actively maintained with a recent release (25 days old) and consistent commit activity. Requires Python 3.12 or later.

License in practice: Licensed under LGPL-3.0-or-later (copyleft). Any derivative work or distribution must preserve the copyleft obligations and make source code available under compatible terms.

Quickstart:

pip install mitmproxy-windows

# Then use with mitmproxy:
mitmdump --mode local:curl

Windows-only package; requires Python 3.12 or later. Development mode compilation of windows-redirector.exe requires a Rust toolchain.

Verify before relying:

- Whether the vendored WinDivert library is kept current with upstream security patches.
- Whether the Rust redirector executable is signed or verified for Windows SmartScreen compatibility.
- Performance characteristics and overhead of the named-pipe redirection approach under load.
