Proxy

关于

Proxy is an advanced HTTP/HTTPS Man-in-the-Middle (MITM) proxy server designed for inspecting and manipulating web traffic. It provides granular control over requests and responses, allowing users to modify headers, bodies, mock responses, and manage traffic flow. Built on mockttp, it integrates robust features like upstream proxy chaining for geo-routing or authentication, and sophisticated TLS fingerprint analysis (JA3/JA4/JA3S) with spoofing capabilities. It also offers a suite of 'interceptors' to seamlessly route traffic from browsers like Chrome, command-line tools, Docker containers, and Android devices through the proxy, making it a versatile tool for developers, testers, and security professionals.

主要功能

• Explicit HTTP/HTTPS MITM proxy with in-flight traffic modification (headers, bodies, mock, drop).
• Supports upstream proxy chaining for global or per-host routing (SOCKS4/5, HTTP, HTTPS, PAC).
• Captures and analyzes TLS fingerprints (JA3/JA4 client, JA3S server).
• Spoofs outgoing JA3 + HTTP/2 fingerprint + header order using curl-impersonate.
• Provides interceptors to automatically route Chrome, CLI tools, Docker, and Android devices.
• 3 GitHub stars

使用案例

• Bypassing geo-restrictions or testing with different IP origins by chaining to upstream proxies.
• Debugging and manipulating web traffic from browsers, CLI tools, or mobile apps during development and testing.
• Analyzing and spoofing TLS fingerprints for security research or anti-bot evasion.
