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.
