killport

Kill the process running on a specific port — instantly.

Tired of the dreaded Error: listen EADDRINUSE: address already in use :::3000?

killport is a zero-dependency CLI tool that instantly identifies and terminates the process hogging your port. Stop googling lsof and taskkill commands—just run one command and get back to coding.

Features

• Cross-Platform: Works seamlessly on Windows, macOS, and Linux.
• Instant: Finds and kills processes in milliseconds.
• Zero Dependencies: Pure Node.js, lightweight and secure.
• Simple: One command, no complex syntax.

Installation
