About:
Killport is a command-line utility designed to immediately terminate any process that is listening on a specified network port. It automatically handles platform-specific details, providing a consistent interface for freeing up ports without manual PID lookup. This tool is essential for developers who need to quickly stop services blocking ports required for new applications or local servers.

Key Features:

Cross-platform support (Linux, macOS, Windows)
Automatic process discovery by port number
Requires no manual PID lookup
Simple, single-command interface

Use Cases:

Freeing up a port blocked by a hanging background process
Stopping a local development server before restarting it
Cleaning up zombie processes occupying standard ports like 8080 or 3000

Alternatives:

lsof – Standard Unix utility requiring verbose flags and piping to kill.
fuser – Linux-specific tool often requiring sudo privileges.
