Vite vs Turbopack

Vite and Turbopack represent the two leading approaches to next-generation JavaScript tooling. Vite (built in JavaScript/Go with Rollup for production) solved the Webpack speed problem by using native ES modules in development. Turbopack (built in Rust) goes further: it's a fully incremental bundler that caches computation at a granular level, so it only re-processes exactly what changed. Vercel claims Turbopack is 10x faster than Vite on startup and up to 700x faster than Webpack on large codebases.

The key architectural difference is scope. Vite works with any JavaScript framework — React, Vue, Svelte, Lit, vanilla JS — through its Rollup-compatible plugin system. Turbopack is currently optimized primarily for Next.js, where it's been integrated as the default development server since Next.js 15. Using Turbopack outside Next.js is possible but not yet the intended use case; the tooling, documentation, and community support are all Next.js-centric.

Production build maturity is Vite's current advantage. Vite's production builds are powered by Rollup, which has been battle-tested for years with excellent tree-shaking, code-splitting, and output optimization. Turbopack's production build mode is still in development and not yet at production-ready status for all applications. For teams that need confident, predictable production builds today, Vite is the safer choice.

The practical decision depends entirely on your framework. Building with Next.js? Turbopack is now the official default and the investment Vercel is making into it means it will only improve. Building with anything else — React without Next.js, Vue, SvelteKit, Astro — Vite is the clear choice with its framework-agnostic plugin ecosystem and mature production builds. In 2-3 years, Turbopack may become a universal default as its production builds mature; for now, choose based on your stack.
