AI process identification
Ask about a running process and get an explanation based on the process command, project, and context, including what it is, why it is running, and whether you should stop it.
Port Radar
Port Radar for macOS helps you identify running processes, inspect listening ports, stop or share local services, and create Cloudflare Tunnel previews.
Overview
Port Radar for macOS is a desktop tool for identifying what is running on your Mac, especially listening ports and background processes. The homepage positions it as a way to ask AI about a process and get a plain-language explanation of what it is, why it is running, and whether it should be stopped.
The product combines process inspection, port grouping, and sharing tools in one macOS app. It can show local services by port, explain likely project ownership, and create a Cloudflare Tunnel for a public preview link when you need to share a local app with someone else.
Features
Port and process scanning
Pick a port or process and get grouped views of listening services such as Vite, Next, Python, Docker, and orphaned processes.
One-click port sharing
Share a local port from the menu to create a Cloudflare Tunnel and generate a public URL for a preview or demo.
Process control
Stop a process with a normal stop or a force quit, with confirmation before action.
Context-rich process details
Shows local app context such as port number, PID, project name, and tunnel status in the interface examples on the site.
Use Cases
Identify local dev servers
When you have a localhost port like 5173 or 3000 open, Port Radar can show the process behind it and explain whether it looks like a local frontend, API server, or orphaned process.
Share a local preview
If you need to send a preview to a teammate or client, you can share a port and generate a public Cloudflare Tunnel URL without using a separate CLI workflow.
Decide what to stop
When a process has been running too long or you are unsure it is needed, the app can help you judge whether it is safe to stop and then let you stop or force quit it.
Audit active ports on your Mac
For a machine with many services running, Port Radar groups listening ports by project or process type so you can scan the set of active services more quickly.
Pros and Cons
Pros
- Explains running processes in plain language using command and project context.
- Helps you see listening ports grouped by project or process type.
- Includes a built-in path to share local apps over Cloudflare Tunnel.
- Provides direct process actions, including graceful stop and force quit, from the same interface.
- States that the app is on-device and private, with no cloud handling mentioned in the homepage copy.
Cons
- The site does not provide pricing details; the /pricing page returned a 404 in the supplied source.
- Apple Intelligence support is shown for macOS 26+, so the AI explanation flow may depend on a newer macOS release than the general app requirement.
- The product page does not document advanced sharing, team permissions, or collaboration controls beyond generating a public tunnel URL.
