Start a local development server that runs your project backend locally on your machine. When your project defines site.serveCommand in base44/config.jsonc, dev also spawns your frontend dev server and manages both processes together. Learn more about local development, including setup and supported features, in the Local development guide.

​
Frontend dev server

If site.serveCommand is set in your project config, dev runs that command from the project root and:
  • Injects VITE_BASE44_APP_ID (your app’s id) and VITE_BASE44_APP_BASE_URL (the local backend URL) into the frontend process’s environment, so the SDK auto-points at the local backend.
  • Streams the frontend’s output alongside the backend’s, prefixed with [backend] and [frontend].
  • Shuts both processes down together when you press Ctrl-C, and tears the backend down if the frontend exits on its own.
If site.serveCommand is not set, dev runs only the backend and you can start your frontend in a separate terminal.
