# Turbopack (beta)

[Turbopack](https://turbo.build/pack) is an incremental bundler optimized for JavaScript and TypeScript, written in Rust, and built into Next.js 13.

On large applications, Turbopack updates 700x faster than Webpack.

Turbopack can be used in Next.js 13 in both the `pages` and `app` directories:

1. Create a Next.js 13 project with Turbopack

```bash
npx create-next-app@latest --example with-turbopack
```

2. Start the Next.js development server (with Turbopack)

```bash
next dev --turbo
```
