The record

Product: Oxc is a collection of high-performance JavaScript tools written in Rust.
Toolchain: Oxc includes a linter, formatter, parser, transformer, resolver, minifier, and TypeScript runner.
Oxlint: Oxlint is a JavaScript and TypeScript linter that the site says is 50 to 100 times faster than ESLint.
Lint rules: Oxlint includes more than 870 rules covering ESLint core, TypeScript, React, Jest, Vitest, Import, Unicorn, and jsx-a11y.
Type-aware linting: Oxlint's type-aware linting uses the native Go port of the TypeScript compiler, tsgo.
Framework support: Oxlint can lint JavaScript and TypeScript, JSX and TSX, and script blocks in Vue, Svelte, and Astro files.
Formatter: Oxfmt is a JavaScript ecosystem formatter with a Prettier-compatible workflow and built-in import, Tailwind CSS class, and package.json field sorting.
Formatter language support: Oxfmt supports JavaScript, TypeScript, JSON, YAML, TOML, HTML, Vue, Svelte, CSS, Markdown, GraphQL, and other formats.
Transformer: The transformer handles TypeScript and JSX, syntax lowering from ES2026 to ES2015, React Refresh, plugins, and isolated declaration emit.
Integrations: Transformer integrations listed by the project include unplugin-oxc, unplugin-isolated-decl, and oxc-webpack-loader.
TypeScript runner: The experimental TypeScript runner runs TypeScript and JSX without a separate build step and supports ESM, CommonJS, source maps, and tsconfig.json.
Runner limitation: The TypeScript runner strips types but does not type-check programs, and its APIs and behavior may change between releases.
Audience: The project recommends Oxlint for JavaScript and TypeScript linting, particularly for large repositories and CI environments.
Ownership: The Oxc site footer identifies VoidZero Inc. and Oxc contributors.
