About

Proxygen

This tool allows developers to intercept, inspect, and modify HTTP traffic from their iOS devices on a Mac. It offers advanced features like JavaScript scripting for traffic manipulation and a syntax-aware editor for debugging API endpoints.

Highlights
  • Send iOS device traffic to Mac
  • Modify proxied traffic with JavaScript
  • Match and replace headers/body data
  • Syntax highlighting HTTP editor
  • WebSocket and SSE message capture
  • Local VPN extension for proxying

Proxygen is the best HTTP proxy tool for testing apps and debugging remote API endpoints right on your iPhone, iPad and Mac. And it’s built to delight you while doing it. Features • Send iOS device traffic to remote Mac • Write JavaScript to modify proxied traffic • Store state in variables for use in Editor • Match and replace headers and body data • Test API endpoints with assertions • Transform data with custom recipes • Syntax highlighting HTTP message editor • Message history with powerful filtering • WebSocket and SSE message capture • Store all data in documents SEND TO MAC Easily capture HTTP messages from an iPhone or iPad on your Mac. Traffic is mirrored to the paired Mac over local network even when the iOS app is not active. The Mac app can intercept and edit data of requests and responses before they are forwarded. No more futzing around with Wi-Fi proxy settings and trusted certificates. SCRIPTING Write JavaScript code that modifies proxied traffic. Scripts have access to requests and responses, letting you rewrite headers, URLs and body content, inject data, or implement conditional logic that goes beyond what static rules can express. SYNTAX AWARE EDITOR Edit requests from the message history or create new to any target. All previously sent requests are kept in the project file so you can return to your work later. The editor uses Tree-sitter for fast language parsing and syntax highlighting. It handles decoding of HTTP content automatically, letting you focus on testing the remote API. SERVER GRADE PERFORMANCE The magic lies in a little custom HTTP proxy that the iOS app runs in a local VPN extension. This proxy was developed using SwiftNIO, a framework for bizarrely fast asynchronous network applications. The proxy can perform TLS Manipulator in the Middle (MitM) to see inside HTTPS connections and apply custom logic to each message. To put it bluntly, you’ve probably never seen a HTTP proxy this fast before. And you likely won’t notice that your web browsing is even proxied at all. PRIVACY Proxygen contains no third party frameworks for crash reporting or analytics. Note that Proxygen is a TLS MitM proxy, which means that it sees HTTPS network traffic in plain text. This data is transferred from the proxy to the Proxygen app and stored as part of the project document. Make sure you handle the documents accordingly, as they may contain sensitive data such as session tokens and login credentials.
