Port Radar is a native macOS menu bar app that shows you exactly what’s running on your ports—in plain English. Spot Vite, Next.js, Docker, forgotten apps, and anything else quietly using resources, then stop it with a single click. Apple Intelligence answers "what is this, is it safe to stop?" right on your device, so nothing leaves your Mac. Plus one click Cloudflare tunnels to share a local site as a live link.
