> Rolldown is currently in beta status. While it can already handle most production use cases, there may still be bugs and rough edges. Most notably, the built-in minification feature is still in alpha status.

# Rolldown

Rolldown is a JavaScript/TypeScript bundler written in Rust intended to serve as the future bundler used in [Vite](https://vitejs.dev/). 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](https://rolldown.rs/about).

## VoidZero Inc.

Rolldown is a project of [VoidZero](https://voidzero.dev/), see our announcement [Announcing VoidZero - Next Generation Toolchain for JavaScript](https://voidzero.dev/posts/announcing-voidzero-inc).

If you have requirements for JavaScript tools at scale, please [get in touch](https://forms.gle/WQgjyzYJpwurpxWKA)!

## Contributing

We would love to have more contributors involved!

- [esbuild](https://github.com/evanw/esbuild), created by [Evan Wallace](https://github.com/evanw).

And supported by:

- [napi-rs](https://github.com/napi-rs/napi-rs) for Node.js add-ons in Rust via Node-API.
