Rspack is a fast, Rust-based JavaScript module bundler for the web that modernizes the webpack API to serve as a drop-in replacement. It offers parallelized builds, lightning-fast HMR, built-in SWC transpilation, Lightning CSS, asset handling, and first-class Module Federation support.
Use cases
- replace webpack with a faster bundler
- speed up slow webpack builds in a large project
- bundle a TypeScript or JSX web application
- get fast hot module replacement during development
- implement micro-frontends with module federation
- migrate from webpack or Create React App with minimal changes
- tree-shake and minify production JavaScript bundles
- use webpack plugins and loaders with better performance
When to choose
- you have an existing webpack project and want dramatically faster builds with low migration cost
- you need compatibility with the webpack plugin and loader ecosystem
- you want built-in TypeScript, JSX, CSS, and asset support without heavy configuration
- you are building micro-frontends or need Module Federation
When to avoid
- you rely on webpack APIs outside Rspack's supported subset, since it is not 100% webpack-compatible
- you prefer Vite's native ESM dev-server workflow and don't need webpack compatibility
- you need a zero-config bundler for a tiny project where setup simplicity matters more than build speed
