Download ProxyPin

ProxyPin is a free, open-source HTTP and HTTPS proxy capture and management tool designed for developers, security researchers, and automation engineers. It works as a local proxy that intercepts and displays all HTTP/HTTPS traffic from your applications, allowing you to inspect, modify, and replay network requests.

ProxyPin supports SSL/TLS decryption, enabling you to view the full content of encrypted HTTPS traffic passing through it. Its clean interface displays request and response headers, bodies, and timing information, making it a useful alternative to tools like Charles Proxy or Fiddler for web debugging and API testing.

It is available as a cross-platform desktop application and also has an Android version, allowing mobile developers to capture and debug network traffic from their apps. ProxyPin is written in Flutter, giving it a consistent UI across all supported platforms.
