Raycast

The portcheck extension for Raycast (macOS) puts your ports one keystroke away.

Command	What it does
Search Ports	Every port listening on your Mac with its process, PID, user and who started it. ⏎ stops it (after confirming), ⌘O opens it in the browser, ⌘C copies the PID; also copy the command line, or the stop command for a Docker port.
Check Port 3000	Free, or which process holds it, who started it and its command; stop it from there.
Kill Port 3000	Stops what listens on the port, after confirming. Never stops system processes.
Find Free Port 3000-3999	Copies a free port, optionally in a range.

Install

Status

The extension is on its way to the Raycast Store. Until then, build it from the repository: cd extensions/raycast && npm ci && npm run dev.

It needs the portcheck CLI (install); the extension finds it in Homebrew, ~/.local/bin or ~/go/bin, or set its path in the extension's preferences.
