Port Scanner

A lean CLI and web dashboard to list ports, kill processes, expose tunnels, and inspect webhook requests — all from your browser.

Features

• List Ports — See every open port with process name and PID
• Kill Processes — One click to terminate any process
• Expose Tunnels — Turn any local port into a public URL via Cloudflare Tunnels
• Request Logs — Inspect every incoming request with method, path, status, headers, and body

Installation

Global (Recommended)

# npm
npm install -g port-scanner-cli

# pnpm
pnpm add -g port-scanner-cli

# yarn
yarn global add port-scanner-cli

Local

# npm
npm install port-scanner-cli

# pnpm
pnpm add port-scanner-cli

# yarn
yarn add port-scanner-cli

Install Cloudflared (for tunnels)

Required only if you want to expose local ports as public URLs.

# Linux / WSL
curl -L https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64.deb -o /tmp/cloudflared.deb && sudo dpkg -i /tmp/cloudflared.deb

# macOS

# Windows (PowerShell)
winget install Cloudflare.cloudflared

Usage

CLI

# List all ports
ports list

# Filter by protocol, state, or process

Web Dashboard

Start the dashboard and open it in your browser:

From the dashboard you can:

• Filter and sort ports by protocol, state, or search
• Kill any process with one click
• Expose a listening port as a public URL (via Cloudflare Tunnels)
• Copy the tunnel URL to your clipboard
• View request logs — see every request hitting your tunnel with method, path, status, headers, and body

Requirements

• Node.js 18+
• Linux: ss or netstat
• macOS: lsof or netstat
• Windows: netstat
• cloudflared (optional, for tunnel feature)
