About:
Surge is a powerful network utility for macOS that enables users to monitor, filter, and manipulate network traffic. It acts as a transparent proxy and firewall, providing deep insights into which applications are communicating over the network. This makes it an essential tool for developers, security researchers, and power users seeking granular control over their network environment.
Key Features:
  • HTTP/S proxy with granular request/response inspection and modification
  • Network traffic filtering and firewall capabilities based on rules
  • Real-time monitoring of network activity per application
  • Scripting support for custom network behaviors and automation
Use Cases:
  • Debugging API calls and network issues for mobile and web development
  • Analyzing network traffic for security research and privacy auditing
  • Bypassing network restrictions or testing applications under different network conditions
Alternatives:
  • Charles Proxy – Charles is a popular GUI-based proxy, while Surge offers more advanced scripting and network-wide filtering capabilities.
  • Little Snitch – Little Snitch is primarily a firewall for blocking connections, whereas Surge provides a full suite of proxy, monitoring, and traffic manipulation tools.
