Description

Proxygen is a professional HTTP proxy tool for testing apps and debugging remote API endpoints right on your Mac, iPhone and iPad. And it’s built to delight you while doing it.

The magic lies in a little custom HTTP proxy. This proxy was developed using SwiftNIO, a framework for blazing 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.

Features
• High performance SwiftNIO HTTP proxy
• Decrypt HTTPS using TLS MitM
• Message history with powerful filtering
• WebSocket message capture
• Intercept and release messages in a queue
• Transform strings with your custom recipes
• Diff two message data between each other
• Test API endpoints with free-form message editor
• Match to request protocol, method, host and URI
• Replace HTTP headers and body data
• Map to local responses without a remote API
• Drop matched requests and responses
• Store message history and editors in project files

NATIVE MAC APP
Proxygen is a native AppKit app, making it look like it actually belongs on the Mac. The app can scroll through thousands of messages and update the list with fluid animations. You can sync and share project files saved on the iPhone with your Mac, and continue where you left off. Intercept HTTP requests and responses and edit their contents before forwarding them to the destination.

FREE-FORM EDITOR
Edit requests from the message history or create new requests to any target. All previously sent requests are kept in the project file so you can return to your work later. The editor handles decoding of HTTP content automatically, letting you focus on testing the remote API.

MATCH AND REPLACE
Proxygen can modify requests and responses, on the fly, according to your custom rules. Multiple rules can be combined to create powerful automations that drop traffic to certain destinations, add or remove HTTP headers and respond locally with custom data, bypassing the remote server.

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.

EddyGeez! ,

The best TLS proxy for iOS

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!
