A lightweight macOS menu bar app that shows all TCP listening ports grouped by process name. Built as a JXA (JavaScript for Automation) stay-open applet.

• Shows all TCP listening ports in the menu bar
• Ports grouped by process name with full command names
• Copy any port number to clipboard with a click
• Kill processes directly from the menu
• Auto-refreshes every 2 seconds
• Instant refresh on app launch/termination via NSWorkspace notifications
• Minimal resource usage (menu bar only, no Dock icon)

• macOS (uses Cocoa frameworks via JXA ObjC bridge)

git clone https://github.com/mnafees/openports
cd openports
./install.sh

This builds the app, copies it to /Applications, and optionally adds it to your Login Items.
