esbuild vs Vite

esbuild is a free bundler for web projects, designed to improve build-tool performance while remaining easy to use. It bundles ESM and CommonJS modules, including CSS modules, with built-in support for JavaScript, CSS, TypeScript and JSX. Optimization features include tree shaking, minification and source maps; development tools include a local server, watch mode and plugins. Developers can use the command-line, JavaScript or Go interface. The recommended installation is the native executable installed with npm. An alternative WebAssembly package works across platforms, though it can be substantially slower than the native package. esbuild is MIT-licensed. It does not type-check TypeScript, and its FAQ recommends running tsc separately. The FAQ describes code-splitting support as primitive. The maintainer says the project receives periodic releases and is maintained, but active feature development is not underway. The FAQ also notes that a project primarily built by one developer may not fit organizations seeking a larger or more active community.

Vite is a free build tool for modern web projects. Its development server serves source files on demand using native ES modules and supports Hot Module Replacement. For production, the `vite build` command bundles application assets for static hosting. Vite supports TypeScript, JSX, CSS, web workers, and WebAssembly; plugins can extend the tool, including its development server and SSR functionality. Its plugin interface builds on Rollup's. Documented framework integrations include Vue, React, Preact, Svelte, Solid, Qwik, Nuxt, SvelteKit, Astro, and React Router. Developers can try Vite in a browser through StackBlitz using supported framework templates. It runs on Linux, macOS, Windows, and the web, and is MIT licensed and free and open source. Vite requires Node.js 20.19+ or 22.12+, though some templates may need a higher version. It transpiles TypeScript but does not type-check it; type checking needs to be handled separately. Legacy browser support can be added with the official `@vitejs/plugin-legacy`.
