A fast, safe, GUI-first utility to identify which process holds a specific port and free that port by terminating the owning process (gracefully, then forcefully if needed). Supports multiple ports, batch actions, and minimal friction across macOS, Windows, and Linux.
- 🔍 Port Scanning: Search for processes using specific ports
- 💀 Process Termination: Graceful or force kill processes
- 🔄 Batch Operations: Terminate multiple processes at once
- 🎯 Source Detection: Identify Docker containers, systemd services, launchd services, and brew services
- 🛡️ Safety First: Confirmation dialogs and permission handling
- 🌍 Cross-Platform: Works on macOS, Windows, and Linux
- 🎨 Modern UI: Clean, responsive interface built with shadcn/ui + Tailwind CSS

- View Results: See all processes using the specified ports
- Terminate Processes:
- Click the orange button for graceful termination
- Click the red button for force termination
- Filter Options: Toggle "Only listening" to show only listening sockets
The application provides a GUI interface. For CLI alternatives, consider using:
lsof -i :PORTnetstat -tulpn | grep :PORTss -tulpn | grep :PORT
- Frontend: React + TypeScript + Mantine UI
- Backend: Rust + Tauri + sysinfo
- Packaging: Tauri bundler for cross-platform distribution
- Port Scanner: Uses system tools (
lsof,netstat) to find port usage - Process Manager: Leverages
sysinfocrate for process information and termination - Source Detector: Heuristics-based detection of service sources
- UI Framework: shadcn/ui components with Tailwind CSS styling
