# Run locally

Use Node.js 24.21.0 (`.nvmrc` included) and npm 12.2.0. Node.js 24.15.0–24.x or 26+ is required by npm 12.

```sh
npm ci
npm run dev
```

Open http://localhost:3000. For production:

```sh
npm run build
npm start
```

`npm start` now runs the Next.js production server; use `npm run dev` for development. Deploy using any Node.js host that supports Next.js. No environment variables or external accounts are required for demo mode. Live assistant mode is optional and requires the server settings below.
