AI Analysis

●●SolidCozySolve My Problem

Menu bar port monitoring beats lsof for daily dev workflow on macOS.

Strengths
  • •Project directory detection from port processes is genuinely useful for context.
  • •Dual CLI and menu bar app serves both automation and visual monitoring needs.
  • •Automatic filtering of system services keeps the view focused on dev servers only.
Weaknesses
  • •macOS-only limits audience — Linux and Windows devs need equivalent tools.
  • •0 stars at launch means no community validation of stability or usefulness yet.
Target Audience

Post Description

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

Would love feedback.
