Oxc is a comprehensive suite of JavaScript and TypeScript development tools built entirely in Rust, created by Boshen Chen and maintained by VoidZero Inc. The project delivers a parser, linter (oxlint), formatter, transpiler, minifier, and module resolver as standalone components that share a common AST representation and compiler infrastructure. The Oxc parser processes JavaScript files up to 3x faster than SWC and 5x faster than the popular acorn parser, establishing a new performance baseline for JavaScript tooling.
The oxlint component has gained particular traction as a practical ESLint alternative, offering over 400 built-in rules that cover ESLint core, TypeScript-ESLint, and popular plugin rules while running 50-100x faster on large codebases. Unlike ESLint, oxlint requires zero configuration out of the box and can lint an entire monorepo in under a second. The transpiler handles TypeScript stripping, JSX transformation, and newer ECMAScript features, providing a faster alternative to Babel and tsc for build pipelines that don't require full type checking.
Oxc serves as the foundational layer for Rolldown, the next-generation Vite bundler, meaning its parser and resolver are battle-tested in production build scenarios across the Vite ecosystem. With over 20,000 GitHub stars, MIT licensing, and regular weekly releases, Oxc has become a reference implementation for high-performance JavaScript tooling. Teams adopting Oxc can incrementally replace individual tools in their pipeline — starting with the linter or resolver — without committing to a full toolchain migration.
