# HTTP Proxy

> Use this tool when you need to capture, modify, and inspect HTTP and HTTPS traffic, solving problems like debugging web applications, testing APIs, and analyzing network communications. It takes in HTTP requests and responses, and outputs modified traffic, logs, and session recordings, with interfaces for Chrome, CLI tools, Docker containers, and Android devices. It's ideal for use cases like penetration testing, web development, and network analysis, where fine-grained control over HTTP traffic is required.

## Description

Runs an explicit HTTP/HTTPS man-in-the-middle proxy that captures requests and responses, lets you modify traffic in-flight (headers, bodies, mock responses, URL rewrites, drops), and supports upstream proxy chaining via SOCKS4/5, HTTP, HTTPS, and PAC. Captures and spoofs TLS fingerprints (JA3/JA4/JA3S) using curl-impersonate in Docker/Podman. Ships interceptors to route Chrome, CLI tools, Docker containers, and Android devices through the proxy, with a DevTools bridge for combined browser automation and wire-level inspection. Includes persistent session recording, HAR import/export, and session replay.
