Rolldown-Vite Beta: Rust-Powered Bundler for Vite Cuts Build Times by Up to 16×

Rolldown-Vite Beta Released

Rolldown-Vite, a Rust-powered bundler for Vite, is now available in beta as a drop-in replacement for the default Vite package. Developed by VoidZero and announced by Evan You on May 30, 2025, it unifies Vite’s build pipeline—replacing both esbuild and Rollup—with a single high-performance tool built on Rolldown and the Oxc toolkit (voidzero.dev).

Early adopters have reported production build time reductions ranging from 3× to 16× and memory usage during builds cut by up to 100× on large projects, making it especially impactful for enterprise-scale applications (voidzero.dev).

To evaluate the preview, alias the vite dependency in your package.json:

{
  "dependencies": {
    "vite": "npm:rolldown-vite@latest"
  }
}

Compatibility covers most frameworks and existing Vite plugins, though some advanced use cases may require tweaks. Refer to the Rolldown-Vite migration guide and report any issues to help stabilize the tool ahead of its planned integration as Vite’s default bundler (voidzero.dev).
