Portsy

Portsy is a macOS menu bar app for watching local development ports and freeing them when needed.

Features

• Watches configurable TCP listening port ranges, defaulting to 3000-9999.
• Shows owning process, PID, bind address, and user for each watched port.
• Hides excluded process names from the list, tray count, and kill-all action.
• Sends SIGTERM first when killing a process, then SIGKILL only if the watched port remains occupied.
• Runs as a Tauri v2 menu bar app with a reusable Rust monitoring core.
