gruyere [--details] [--port PORT] [--user]

gruyere is a tiny and visually appealing TUI program for viewing and killing processes that are listening on network ports. It provides a cleaner alternative to manually using lsof or ss to find which process occupies a port, presenting the information in a readable terminal interface with the ability to terminate processes directly.
The tool displays process names, PIDs, and port numbers in a formatted view, making it easy to identify and manage port conflicts during development.

Requires appropriate permissions to view and kill processes. Killing system processes may require root privileges. Only shows processes with active listening sockets.

gruyere was created by Savannah Ostrowski as a lightweight utility for developers who frequently need to identify and free up occupied ports. It is written in Rust and named after the Swiss cheese known for its holes, a playful reference to network ports.
