About Port Radar for macOS
Port Radar is a native macOS menu bar utility that shows every process currently listening on a local port — forgotten Vite servers, stray Next dev processes, Python scripts, Docker containers, and orphans — grouped by the project that owns them, with PID, command line, and uptime. Its distinguishing feature is an Apple Intelligence panel: pick any process and ask in plain language what it is, why it is running, and whether it is safe to stop, and the answer is generated entirely on-device with nothing leaving the Mac. It also folds in one-click sharing, spinning up a Cloudflare quick tunnel from the process menu and handing back a public URL for a local app, auto-installing cloudflared so there is no CLI setup or account flow. Processes can be stopped gracefully or force-quit with confirmation, so you never hunt PIDs in a terminal again. The app is free and open source under Apache 2.0, runs on macOS 14 and later on both Apple Silicon and Intel, and enables the Apple Intelligence features on macOS 26 and above.
