Port Radar for macOS
Explains what's running on a busy Mac port and lets you kill or share it.
Port Radar scans every listening port on your Mac, groups them by project (Vite, Next, Python, Docker, orphans), and uses on-device Apple Intelligence to answer questions like whether a process is safe to stop or why it's been running 14 hours, without sending anything to the cloud. It can also spin up a one-click Cloudflare tunnel to turn a local dev server into a public URL, no ngrok account or CLI needed. Stopping a process offers a graceful stop or force quit, both with confirmation.
What holds up
- +Runs entirely on-device via Apple Intelligence — nothing about your processes goes to the cloud
- +One-click Cloudflare tunnel shares localhost publicly without an ngrok account or CLI
- +Open source under Apache 2.0 — source is on GitHub to inspect
Mind the limits
- −AI explanations need Apple Intelligence on macOS 26+ — older macOS loses that feature
- −First launch is blocked by Gatekeeper since the app isn't notarized yet
