PortKiller

PortKiller for Windows — quick, local port & process inspector with one-click kill and watchlists.

A Windows port of @jamiepine’s Port Killer, rebuilt for Windows using a modern Tauri + React stack.

PortKiller is a lightweight Windows utility that scans listening ports in real time, lets you kill the owning process from the UI, watch favorite ports, and receive system notifications — all with configurable refresh and keyboard-first controls.

✨ What it does (features)

• Real-time Port Scanning: Lists all listening ports (parsed from netstat).
• Process Management: Kill processes directly from the UI.
• Favorites & Watch List: Save frequently used ports and get notifications when they start/stop.
• Automatic Process Type Detection: Categorizes services (web, database, dev, system, other).
• Multiple Views: Toggle between List view and Tree view.
• System Tray Support: Minimize to tray and access quick actions.
• Auto-refresh: Configurable intervals for live monitoring.
• Keyboard-First Controls: Efficient keyboard shortcuts for common actions.
