A Rust-based platform for fast JavaScript and TypeScript compilation and bundling.
Ideal for developers needing fast compilation of modern JavaScript applications.
Can be used within existing toolchains to improve performance and efficiency.
SWC helps developers compile and bundle JavaScript and TypeScript code quickly and efficiently, addressing performance issues with traditional tools.
SWC supports custom plugins and can be integrated into various build systems like webpack and Rspack.
Achieves significant speed improvements over traditional tools like Babel.
Handles JavaScript and TypeScript compilation, minification, and transformation with WebAssembly.
Actively developed and maintained by a community of contributors.
swc and Babel both transform modern JavaScript and TypeScript for production builds. swc is the better fit when build speed matters most; Babel is still the safer choice when a project depends on Babel-specific plugins, presets, or unusual transform behavior.
| Feature | swc | Babel |
|---|---|---|
| License | Apache-2.0 | MIT |
| Runtime model | Rust compiler with JavaScript and Rust bindings | JavaScript compiler and plugin system |
| Migration path | Documents a CLI replacement path from npx babel to npx swc | Existing default in many older JavaScript build chains |
| Performance focus | Publishes benchmarks against Babel and esbuild | Prioritizes compatibility and plugin coverage |
Choose swc for large TypeScript or JavaScript projects where transform time slows local development, CI, or bundler pipelines. The Rust compiler model makes swc especially strong inside frameworks, monorepos, and build tools that run many transforms in parallel.
Choose Babel when your build depends on custom Babel plugins, long-tail proposal transforms, or framework tooling that has not validated swc compatibility. swc is the faster compiler for most standard transforms, but Babel still wins when plugin compatibility matters more than raw speed.
npm install -D @swc/cli @swc/coreSWC is a Rust-based platform for fast JavaScript and TypeScript compilation and bundling.
SWC is significantly faster than Babel, achieving up to 70x speed improvements.
Yes, SWC can be integrated into various build systems like webpack and Rspack.
