About:
Netiquette is a lightweight network monitoring tool for macOS that displays active network connections in real-time. It provides detailed information about each connection, including the process responsible, remote address, and port. This allows users to easily identify potentially unauthorized or suspicious network activity on their device.
Key Features:
  • Real-time monitoring of all incoming and outgoing network connections
  • Detailed process information for each connection (PID, name, path)
  • Clear visualization of remote IP addresses and ports
  • Lightweight and unobtrusive design
Use Cases:
  • Monitoring for suspicious network activity or potential malware
  • Debugging network-related issues for specific applications
  • Verifying that applications are communicating with expected servers
Alternatives:
  • Little Snitch – More advanced firewall with complex rule configuration, while Netiquette offers simpler, passive monitoring
  • lsof – Command-line utility providing similar data but without a graphical interface
