Proxygen is a professional 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
• 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.

Not sure what's up with the other review, but this app is a fantastic way to debug apps that use remote API endpoints. You can tell the author spent a lot of time tuning the UI to be useful to somebody that needs to do this sort of thing! You can even set it up to respond with local responses during app devlopment when a remote API endpoint is not yet available (which also allows you to to test how your app reacts with unexpected responses). Great stuff!
Really user friendly app

In future updates, please add the ability to send multiple requests simultaneously or at specific scheduled times. Additionally, consider improving the app's penetration testing capabilities.
Good alternative to Proxyman and Charles Proxy
Dichromatic-
I have been looking for an alternative to Proxyman and Charles Proxy. It’s cheaper and works just as well.The setup can be more streamlined though. Proxyman has one click setup for iOS simulator and Android emulators. I have to manually set the proxy settings right now. I also wish this supports GRPC as well.
App is just file browser with Proxygen name?
caws523
Launching the app, I was presented with the typical iOS file browser except it was named Proxygen and within in the sidebar had text “Proxygen” instead of “Files”. Does the app in the screenshots even exist? Unable to find method to contact developer via email or web form. Will revise review if developer is able to assist.
Developer Response
It’s a document based app. Create a document in Proxygen’s document folder with the plus button.Edit: So I guess you didn’t revise the review after all. Thanks buddy.
VARIABLES
• Store values such as auth tokens and identifiers in environment variables. Then use them in requests in Editor tool using {{name}} syntax.
• New getVariable and setVariable utility functions in scripting.
NEW COLOR THEMES
• Many new editor themes such as Dracula, Nord and Monokai.
Notice how we bring new features and major improvements in every app update? If you like Proxygen app and it helps you debug network traffic then please tell your friends and colleagues about it. That would help a lot!
