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.
Proxygen is a professional HTTP proxy tool for testing apps and debugging remote API endpoints right on your iPhone, iPad and Mac.
Note that Proxygen is a TLS MitM proxy, which means that it sees HTTPS network traffic in plain text.
The proxy can perform TLS Manipulator in the Middle (MitM) to see inside HTTPS connections and apply custom logic to each message.
This data is transferred from the proxy to the Proxygen app and stored as part of the project document.
