A native macOS menu-bar app that shows every port your Mac is running — and explains what's behind each one.
- See every localhost listener, grouped by project
- Ask Apple Intelligence what a process is and whether it's safe to stop (on-device, nothing leaves your Mac)
- Stop or force quit anything, with confirmation
- Share any local app as a live public URL via one-click Cloudflare tunnel
Requires macOS 14 or later. Ask requires Apple Intelligence (macOS 26+ on a supported Mac).
Install
Download Port-Radar.dmg, open it, drag Port Radar to Applications.
First launch: macOS will block it because this build isn't notarized yet. Go to
System Settings → Privacy & Security, scroll to the bottom, and click Open Anyway.
You only need to do this once.
Prefer the terminal?
xattr -cr "/Applications/Port Radar.app"Or build from source — no dependencies beyond the Swift toolchain:
git clone https://github.com/juansebsol/port-radar-mac
cd port-radar-mac && make run
