Share your prototype on your local network

Let someone else on the same Wi‑Fi open your in-progress prototype.

Goal

Share your prototype with someone nearby without deploying it.

Steps

  1. Start your dev server
  • npm start (or npm run dev)
  1. Find the LAN URL
  • Many dev servers print something like:
    • Local: http://localhost:3000
    • Network: http://192.168.x.x:3000
  1. If you don’t see a network URL
  • Find your IP address (Mac):
    • System Settings → Network → Wi‑Fi → Details
  1. Give the URL to a colleague
  • Example: http://192.168.1.9:3000

Common problems

  • Firewall blocks it → allow incoming connections for Node / your dev server.
  • Different Wi‑Fi → they must be on the same network.
  • VPN → can interfere; try disabling if it’s safe to do so.
