portman

A zero-dependency CLI that finds and kills processes on localhost ports — no more lsof -i :3000 → kill -9 → repeat.

Install

pip install portman

Usage

portman list          # List all listening ports
portman find 3000     # Find what's using port 3000
portman kill 3000     # Kill process on port 3000
portman free          # Show free ports

Requirements

Python 3.11+, stdlib only.
