Surge is a web development and proxy utility. It is designed for developers and therefore requires professional knowledge to use.

These four capabilities form the core workflow of Surge:

· Takeover: You can take over the network connection sent by the device. Surge supports both proxy service and virtual NIC takeover.

· Processing: You can modify the network requests and responses that have been taken over. This includes URL redirection, local file mapping, custom modification using JavaScript, and many other methods.

· Forwarding: You can forward the taken over network requests to other proxy servers. This can be global forwarding or with a flexible rule system to determine an outbound policy.

· Intercept: You can intercept and save specific data of network requests and responses, and you can also decrypt HTTPS traffic with MITM.

Highlighted Features

· Takeover all HTTP/HTTPS/TCP traffic from any applications on your device, and redirect to an HTTP/HTTPS/SOCKS5/SOCKS5-TLS/SSH proxy server following highly configurable rules.

· Record and display HTTP requests and responses sent from your iOS devices, including body and header.

· Configure rules using domain match, domain suffix, domain keyword, CIDR IP range, and GeoIP lookup.

· Measure traffic usage and network speed on WiFi, cellular, and proxy connections.

· High performance and suitable for intensive use.

· Block ads by domain rules.

· Local DNS Map (equivalent to /etc/hosts). You can use this function to switch the production/development environment for your app without changing any code.
