• Vite - the build tool for the web
• Vitest - Vite-native test runner
• Rolldown - The fastest bundler
• Oxc - The fastest language toolchain

We are building the next-generation of toolchain for JavaScript that is:

• Unified: using the same AST, resolver, and module interop for all tasks (parsing, transforming, linting, formatting, bundling, minification, testing), eliminating inconsistencies and reducing redundant parsing costs.

• High Performance: written in a compile-to-native language, designed from the ground up for speed, with maximum parallelization and low-overhead JS plugin support. The performance budget unlocks more ambitious features that improve not only developer experience, but end user experience as well.

• Composable: each component of the toolchain is independently consumable, offering building blocks for advanced customization.

• Runtime Agnostic: not tied to any specific JavaScript runtime—delivering the same developer experience across all environments.
