Parcel vs Vite

Parcel is a free, open source, zero-configuration build tool for web projects. It handles HTML, CSS, JavaScript, TypeScript, JSX, Flow, images, fonts, videos, Sass, SVG, Vue, Node, Electron, GraphQL, MDX, XML and other file types out of the box. It can automatically install plugins and development dependencies for additional file types. For development, Parcel includes an HTTPS server with an API proxy and automatically updates code in the browser, with React Fast Refresh and Vue hot-reloading integrations. Terminal and browser diagnostics include syntax-highlighted code frames, hints and documentation links. Production features include tree shaking, minification, image optimization, code splitting, content hashing, and Gzip and Brotli compression. Builds use worker threads and caching, with lazy development builds also supported. Parcel can target declared browser environments, handle workers, build libraries for multiple targets and build monorepos with one command. A plugin system and programmatic API support customization and integration into existing build systems. Its development server builds only one target at a time and defaults to a modern browser target; compression is not enabled by default.

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`.
