Proxyman

Proxyman sits between your apps and the network and shows you every request: headers, bodies, timings, decrypted TLS. From there you can filter and full-text search the log, set breakpoints to pause and edit a request or response before it continues, use Map Local and Map Remote to swap in a file or another endpoint, replay or compose requests by hand, and run JavaScript against traffic with the scripting tool. It handles WebSocket and GraphQL, throttles the connection to simulate bad networks, and walks you through trusting its certificate on a simulator or a real device.

Why it makes the list

The long-time tool here, Charles, is a Java app that looks and feels like one. Proxyman is the native answer — a real Mac interface, a command palette, sensible defaults — while matching the feature set that made Charles indispensable. For debugging an API or a mobile app's network layer, it's the one to reach for now.
