SWC

Rust-based platform for the Web

SWC is an extensible Rust-based platform for the next generation of fast
developer tools. It's used by tools like Next.js, Parcel, and Deno, as well as
companies like Vercel, ByteDance, Tencent, Shopify, and more.

SWC can be used for both compilation and bundling. For compilation, it takes
JavaScript / TypeScript files using modern JavaScript features and outputs valid
code that is supported by all major browsers.

🏎

SWC is 20x faster than Babel on a single thread and 70x faster on four cores.
