🚧 Work in Progress

Rolldown is currently in active development and not usable for production yet.

Rolldown is a JavaScript/TypeScript bundler written in Rust intended to serve as the future bundler used in Vite. It provides Rollup-compatible APIs and plugin interface, but will be more similar to esbuild in scope.

For more information, please check out the documentation at rolldown.rs.

Rolldown is a project of VoidZero, see our announcement Announcing VoidZero - Next Generation Toolchain for JavaScript.

If you have requirements for JavaScript tools at scale, please get in touch!

We would love to have more contributors involved!

To get started, please read our Contributing Guide.

The Rolldown project is heavily inspired by:

• Rollup, created by Rich Harris and maintained by Lukas Taegert-Atkinson.
• esbuild, created by Evan Wallace.

And supported by:

• napi-rs for Node.js add-ons in Rust via Node-API.
• oxc for the underlying parser, resolver, and sourcemap support.
