What is Port Radar for macOS?
Port Radar for macOS is a desktop utility that reveals every listening port on your Mac, grouped by project (Vite, Next.js, Python, Docker, and more). It goes beyond a simple port scanner by integrating with advanced AI capabilities: you can ask in plain English about any process, whether it's safe to stop, why it's been running for hours, or which project owns a particular port, and get an on-device, private explanation. The app also features one-click sharing via Cloudflare tunnels, turning localhost into a public URL for teammates or clients without needing a CLI or external accounts.
Pros & Cons
Pros
- Tight AI integration provides context about processes without leaving the tool

- Open source under Apache 2.0 license
Cons
- Requires macOS 14+ and advanced AI capabilities, limiting compatibility with older systems
- First launch requires manual approval in System Settings because the app isn't notarized

Port Radar for macOS FAQ
Can Port Radar identify orphaned processes that no longer belong to any active project?
Yes, Port Radar groups orphan processes separately in its scan view (labeled 'orphan'), making it easy to spot and stop leftover listening ports that aren't tied to a recognized project like Vite, Next.js, or Python.
Does Port Radar require me to install any tunnel service to use the Share feature?
The Share feature auto-installs cloudflared on first use, so you don't need to manually set up Cloudflare tools or create an account. It generates a public URL immediately.
What types of questions can I ask Apple Intelligence about a running process?
You can ask in plain English questions like 'Is this safe to stop?', 'Why has this been up 14 hours?', or 'Which project owns this port?' The app reads the command, project, and context to give an on-device, private answer.
How does Port Radar handle stopping processes — does it always terminate them?
No, Port Radar offers two options: a 'Stop' button that performs a graceful termination with confirmation, and a 'Force Quit' option for stubborn processes. It never kills a process without your explicit confirmation.
Is Port Radar compatible with Intel-based Macs, or only Apple Silicon?
The app supports both Apple Silicon and Intel Macs, as long as they run macOS 14 or later. Apple Intelligence features require macOS 26+ and a compatible device.
Can I share a port that is not currently running a local server?
Port Radar only shows listening ports (currently active). You cannot share a port that has no active process. You must first start the local service so it appears in the scan list, then use the Share option.
Does the app send process data to the cloud when I use the Apple Intelligence feature?
No, all Apple Intelligence queries are processed on-device. No process data leaves your Mac — the app explicitly states it's on-device and private.
What happens if I stop a process that is critical to my system — will Port Radar prevent that?
Port Radar provides information via Apple Intelligence to help you decide, but it does not prevent you from stopping any process. It labels orphan and unknown processes, but ultimately the decision to terminate is yours.
