ProxyPin is an open-source tool designed to capture, inspect, and manipulate HTTP(S) traffic across multiple platforms, including Windows, macOS, Linux, Android, iOS, and Flutter applications. It provides developers and network professionals with a powerful yet intuitive way to debug and analyze web traffic.
Key Features:
Mobile QR Code Connection: Seamlessly connect devices without manual proxy configuration, enabling cross-device traffic forwarding.
Domain Filtering: Target specific domains to capture only relevant traffic, reducing interference from unrelated applications.
Search & Scripting: Use JavaScript scripts to process requests or responses and search for traffic based on keywords or conditions.
Request Manipulation: Rewrite, redirect, or block HTTP(S) requests, modify messages, and simulate local responses without server interaction.
History Tracking: Save and review captured traffic, export data in HAR format for further analysis, and import HAR files for comparison.
Audience & Benefit:
Ideal for developers, QA engineers, and network administrators seeking a versatile tool to debug web applications or analyze network behavior. ProxyPin simplifies HTTP(S) inspection across platforms, enabling efficient troubleshooting, testing, and development without complex setups.
ProxyPin can be installed via winget on supported systems, offering a seamless integration into workflows for those managing HTTP(S) traffic.
