What Rsbuild is
Rsbuild is a web application build tool powered by Rspack, with both zero-configuration setup and a configurable build API. Rspack is its default bundler, while SWC transforms and minifies JavaScript and TypeScript. Framework plugins support React, Vue, Svelte, Solid, and Preact. Hot module replacement is enabled by default during development, and production builds enable JavaScript and CSS minification by default. Optional styling integrations include Tailwind CSS, UnoCSS, Sass, Less, and Stylus. Rsbuild works with most webpack plugins and all Rspack plugins, and supports Module Federation for micro-frontend applications. The listed capabilities also include TypeScript, code splitting, tree shaking, source maps, and a plugin API. Rsbuild is free and open source under the MIT license; its listed plan is free. The v2 quick start requires Node.js 20.19+ or 22.12+, while v1 requires Node.js 18.12.0 or later. Documentation links to a StackBlitz example and a Discord community. The documentation cautions that open CORS settings can expose the development server and public production source maps can expose source code.
