## What it is
ProxyPin is a free, open-source HTTP(S) traffic capture application built with Flutter, supporting Windows, Mac, Linux, Android, and iOS. It lets developers intercept, inspect, rewrite, block, and mock HTTP(S) requests, serving as a cross-platform alternative to Charles and Fiddler.

## Use cases
- capture and inspect https traffic from mobile apps
- debug flutter app network requests
- rewrite or mock api responses during development
- intercept traffic on windows mac linux android ios
- export captured requests as har files
- block or redirect specific urls while testing
- decrypt encrypted request bodies with aes keys
- write javascript scripts to modify requests and responses

## When to choose
- you need a free open-source alternative to Charles or Fiddler
- you want one traffic capture tool that works across desktop and mobile
- you need to capture traffic from Flutter apps
- you want QR-code based mobile proxy setup without manual wifi configuration
- you need request rewriting, mapping, or blocking during api debugging

## When to avoid
- you need low-level packet capture beyond http(s), such as raw tcp or udp analysis
- you require deep integration with an existing proxy ecosystem or plugins from other tools
- you only need simple curl-style request testing without interception
- you need official support or enterprise-grade compliance guarantees
