Proxygen
Proxygen is a native HTTP proxy tool for app developers who need to see exactly what their apps are sending and receiving. It runs on Mac, iPhone, and iPad, letting you intercept, inspect, and edit HTTP traffic without wrestling with Wi-Fi proxy settings or trusted certificates.
What it does
- Send to Mac — Pair your Mac over the local network and mirror HTTP traffic from your iPhone or iPad instantly.
- Intercept and edit — Catch requests and responses in real time, modify their contents, and process them from a manageable queue.
- Automation — Replace placeholders with test payloads, generate numbers, dates, or character combinations, and run tests with parallel worker threads.
- Diff — Compare any two HTTP messages to spot changes in headers, payloads, or binary content.
- Broad protocol support — WebSocket and SSE monitoring, HTTP-aware syntax highlighting, and scripting with JavaScript.
Built for Apple platforms
Proxygen is a native Swift app with a one-time license. The Mac version includes the complete feature set, while the iOS app brings the same message log, WebSocket inspection, and editor to mobile workflows. Documents use the same format across devices, so you can AirDrop a session from your iPhone to your Mac and keep working.
Pricing
