mitmproxy is a powerful intercepting proxy that captures and analyzes HTTP traffic with precision. Whether you're debugging web applications, testing APIs, or conducting security assessments, it provides real-time visibility into every request and response flowing through your network.

The tool offers three distinct interfaces to match your workflow:

mitmproxy: An interactive console interface with full TLS/SSL support for encrypted traffic inspection
mitmdump: A command-line tool perfect for scripting and automation, comparable to tcpdump but for HTTP
mitmweb: A web-based dashboard for those preferring graphical interaction

Key capabilities include request and response manipulation, allowing you to modify headers, bodies, and parameters on-the-fly. Protocol support spans HTTP/1, HTTP/2, and WebSockets, ensuring compatibility with modern web technologies. The tool excels at request replay, enabling you to resend captured traffic with variations to test different scenarios.

Designed for penetration testers and developers, mitmproxy integrates seamlessly into security workflows and development pipelines. Its Python-based architecture supports custom scripting for advanced use cases, making it adaptable to specialized testing requirements. The active community and comprehensive documentation ensure you have resources to master even complex interception scenarios.
