Localhost 3000

Run and manage your local web projects from one native macOS dashboard.

What it does

✦Scan one portfolio root and list every project that exposes a dev script

✦Start and stop local dev servers from a native macOS dashboard

✦Track assigned ports and edit them inline before the next launch — works even if the project hardcodes a port

✦See which projects have uncommitted git changes before you run them

✦Open running apps in the browser or copy a network URL to test on another device

✦Scan a QR code to open any running project on your phone instantly

✦Jump straight into Terminal, VS Code, or Finder from the same row

✦go/ links — type go/alias in Chrome to open any project without touching a port number

✦Menu bar quick launch — start and stop servers without opening the app at all

Who this is for

Developer command center

Manage a folder full of client sites, experiments, and portfolio apps without opening separate terminal tabs for each one.

Cross-device testing

Copy the local network URL for a running project and open it on a phone or tablet on the same Wi‑Fi — or just scan the QR code.

go/ links

Assign a short alias to any project and just type go/alias in Chrome to open it. No port numbers, no bookmarks.
