Proxyman

About

Proxyman sits between an app and the network so you can see what it actually sends. It captures HTTP and HTTPS traffic from a Mac or a connected device, decrypts TLS with a one-click certificate install, and shows each flow with headers, a JSON or XML body, timing and size, with filtering and search that cope with thousands of rows. Watching is only half of it: a breakpoint lets you edit a request or response in flight, Map Local answers a call from a file, and there are tools for composing requests, throttling the connection and reissuing a call with changes. The same debugger handles iPhone and Android traffic, and the free build covers a couple of pinned domains while the one-time licence lifts the limits.
