Seeports is a macOS menu bar utility that shows every TCP port listening on your Mac. Ports are automatically grouped by service—Docker, OrbStack, Kubernetes, Cloudflare, and more—so you can instantly see what's running without reaching for the terminal. Click any port to copy its localhost URL, open it in your browser, or search for documentation. Rogue processes can be terminated or force killed directly from the menu. Multiple scanning strategies including lsof, libproc, and bind probing ensure comprehensive detection, with configurable auto-refresh intervals from 2 to 60 seconds. Individual ports or entire process groups can be hidden to reduce noise. The entire app fits on a floppy disk at under 300 KB.
