Rolldown is a fast JavaScript/TypeScript bundler written in Rust with a Rollup-compatible API and esbuild feature parity. It is designed to become the unified bundler powering Vite 8+ and can also be used standalone or for library bundling via tsdown.

Use cases

• bundle a javascript or typescript application faster than rollup
• replace rollup and esbuild with a single rust bundler
• bundle a typescript library for npm publishing
• speed up vite production builds
• bundle tens of thousands of modules with minification and source maps
• migrate an existing rollup config and plugins to a faster bundler

When to choose

• you want rollup-compatible APIs and plugin ecosystem with much faster builds
• you use Vite and want its next-generation unified bundler
• you need esbuild-style transforms, minification, and define/inject built in
• you bundle very large codebases where bundling speed matters

When to avoid

• you rely on webpack-specific features or loaders
• you need a bundler on an unsupported platform without wasm fallback
• you require a long-proven tool with years of production hardening and prefer stability over speed
