Show HN: Pscan – a macOS menu bar app to monitor your localhost ports

2•dogancna•2h ago
I juggle multiple dev servers daily and got tired of forgetting which port runs what. So I built pscan — a tiny menu bar app that scans for active localhost ports, detects which project directory they belong to, and lets you open them in browser, terminal, or finder with one click. You can also kill processes directly from the dropdown.

It filters out system services automatically so you only see your dev servers. There's also a CLI version.

Menu bar app: https://github.com/mavideniz/pscan/releases/latest

CLI: brew install mavideniz/pscan/pscan

Source: https://github.com/mavideniz/pscan

Would love feedback.
