Oxc vs Parcel

Oxc is a free collection of JavaScript tools written in Rust, available for Linux, macOS and Windows. Its toolchain includes a linter, formatter, parser, transformer, resolver, minifier and TypeScript runner. Oxlint checks JavaScript and TypeScript, including JSX, TSX and script blocks in Vue, Svelte and Astro files. It includes more than 870 rules across areas such as TypeScript, React, Jest, Vitest, imports, Unicorn and accessibility. Type-aware linting uses tsgo, a native Go port of the TypeScript compiler. Oxfmt follows a Prettier-compatible workflow and can sort imports, Tailwind CSS classes and package.json fields; it formats JavaScript, TypeScript, JSON, YAML, TOML, HTML, Vue, Svelte, CSS, Markdown, GraphQL and other formats. The transformer handles TypeScript and JSX, syntax lowering from ES2026 to ES2015, React Refresh, plugins and isolated declaration output. An experimental runner executes TypeScript and JSX without a separate build step, with ESM, CommonJS, source map and tsconfig.json support. It strips types but does not type-check programs, and its APIs and behavior may change between releases.

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.
