PortAura is a native macOS utility that shows which processes are listening on which ports, where they’re exposed, and what has changed since your trusted baseline. It helps you understand local services without digging through Terminal commands. Everything runs locally on your Mac.
I built PortAura because I kept running into the same question on my Mac: what is actually listening on this port, which process owns it, and is this something new?
Terminal tools can answer that, but the information is scattered and not always easy to read at a glance.
PortAura brings ports, processes, exposure scope, and baseline changes into one native Mac interface. A baseline change doesn’t automatically mean risk — it simply gives you a clear signal that something changed and is worth reviewing.
Everything runs locally on your Mac. No account, no cloud dashboard, and no unnecessary background service.
I’d really appreciate feedback from Mac users and developers on what would make this more useful.
