What is this?
ProxyPin is a free, open source tool for capturing HTTP(S) traffic: it intercepts, inspects and rewrites requests and responses, and it can even capture traffic from Flutter apps. Think of it as an open alternative to Charles or Fiddler.

The README also links a Telegram channel for updates.

The GUI and scan-to-connect setup keep the entry bar low.

You can redirect or rewrite requests, replace request or response bodies, block requests by URL, and use request mapping to answer from a local config or script without ever calling the real server. JavaScript scripts and automatic AES body decryption are built in too.
