Turbopack

Also known as: Turbopack

Vercel's Rust-powered JavaScript bundler, designed as a Webpack successor. Incremental caching dramatically speeds up dev server startup and HMR for large projects. Default in Next.js 15+.


Overview

Turbopack is a bundler written in Rust from the ground up, drawing on Webpack experience. Its fine-grained incremental computation cache rebuilds only what is affected by each file change. It became the default Next.js 15 dev server, with production build support expanding.

Comparison with Vite

Vite features fast native-ESM bundling via esbuild and is the standard build tool for non-Next.js frameworks (Svelte, Vue, Remix, etc.). Turbopack's advantage is most pronounced in large Next.js projects.
