The macOS menubar port monitor
See every open port, running tunnel, and background process — all from your menubar. Kill rogue processes, monitor Cloudflare Tunnels, and take back control of your network stack.
Real-time TCP port listing with process names, PIDs, app icons, and smart labels. Know exactly what's running and where.
Live sync with cloudflared. Health status indicators, quick tunnel support, and edge location info — all at a glance.
Kill any process from the context menu. Graceful SIGTERM with automatic SIGKILL fallback when things get stubborn.
Native performance with minimal resource usage. No Electron bloat.
Snappy UI with real-time updates. Renders in the native webview.
macOS vibrancy effects. Feels like it belongs on your Mac.
Lives in the menubar. No Dock icon. No window clutter. Just there when you need it.
