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.

Dafür hätte ich auch 30€ gezahlt wenn ich davor die Pro-Features testen könnte. Match-Replace, Scope, Vars sind für mich extrem wichtig. Alles da. Falls etwas fehlt melde ich mich (: ### 5/5 — Very helpful for verifying DoH too *2026-02-16* This app can even capture DNS over HTTPS (DoH) requests. It is very helpful for verifying DoH settings. **Developer response:** That’s amazing! To be honest I never even tested DNS over HTTPS but great to hear it’s working 💪 ### 5/5 — Good alternative to Proxyman and Charles Proxy *2025-08-16* 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. ### 5/5 — Really user friendly app *2025-05-05* 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. ### 1/5 — App is just file browser with Proxygen name? *2025-03-25* 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. ### 5/5 — Really impressed so far, exactly what I needed *2025-01-12* I stumbled upon this app searching for a native MITM proxy app with a rich feature set. I must say that I am really impressed so far, especially with the unique project based approach it employs which makes it easier to work with compared to other alternatives. The iCloud sync is seamless and very convenient to import mobile data to desktop. The iOS/iPad apps are the cleanest UI I have seen in this category. Desktop version needs few improvements though, like automatic proxy config to make it on par with the mobile version. Definitely worth looking into, a great contender in this niche imo. Very fair price too. Recommended! ### 1/5 — J *2025-01-12* Have more block options **Developer response:** Have more words in your app reviews. ### 5/5 — FiveStar *2024-02-15* Downloaded a different one before on mother phone for £4.99. This app does a better job and also for free. ### 5/5 — Going back in the office for *2023-08-06* Come on the next ### 5/5 — Did you see my call *2023-06-28* Call me if you’re still free to ## Frequently asked questions about Proxygen ### What is Proxygen? Proxygen is an interactive HTTP proxy tool designed for developers to test applications and debug remote API endpoints directly on their iPhone, iPad, and Mac. It allows for detailed inspection and modification of network traffic. ### How does Proxygen send iOS device traffic to a Mac? Proxygen utilizes a local VPN extension on the iOS device to capture HTTP messages. This traffic is then mirrored to a paired Mac over the local network, even when the iOS app is not actively in the foreground. ### Can I modify proxied traffic with Proxygen? Yes, Proxygen allows you to write JavaScript code to modify proxied traffic. This scripting capability enables rewriting headers, URLs, body content, and implementing conditional logic beyond static rules. ### What are the subscription options for Proxygen?
