Proxygen

In my information security day job as an application pentester, I often wanted a simple, fast but powerful tool to inspect HTTP traffic. I had a pretty good idea what I wanted, a proxy application somewhere between a security tool and a developer tool. There just wasn't one available that would be well suited to both hacking and QA testing. I remember later visiting a security conference and spending some time at a small hacking contest there. I didn't have my laptop with me, only my iPhone, and could not really participate. This is when I decided I really want to make the HTTP proxy tool I had been thinking about. Proxygen is a professional HTTP proxy tool that can capture traffic using TLS MitM both on Mac and iPhone. It comes with a set of powerful tools, Intercept for stopping and editing requests and responses on the fly, Transform for quickly applying a recipe of encoding operation to any data, and Diff for blazing fast diffing between any two data. The most recent 2.0 update also added WebSocket message inspection. It's a fully native modern Cocoa app on Mac and works great with a simplified UI on both iPhone and iPad. I'm quite proud of the user experience and what I've accomplished. The app is free for basic use with an optional Proxygen Plus subscription that unlocks all functionality. Try it out and tell me what you think! I'm happy to receive any feedback for this app.
