What's on port 3000? Every port on your Mac, by project

Updated 7 October 2026

Unhogged lists every server listening on your Mac with its port, the project and command behind it, and how many connections it has right now. Dev servers that have gone quiet are called out, and one click stops a server and frees its port.

What you see

  • Each port, with the program, project folder and command.
  • Live connections, so you can tell a server you're using from one that's idle.
  • macOS's own ports labelled, like AirPlay Receiver on 5000 and 7000.
  • Idle dev servers flagged, with the memory they hold.
