# Oxc Oxc is a suite of JavaScript/TypeScript tools rewritten in [[Rust]], maintained by VoidZero — the company Evan You (Vue, [[Vite]]) founded to rebuild the JS toolchain layer by layer, acquired by [[Cloudflare]] in June 2026 (tools stay MIT and vendor-agnostic). The bet: linting, formatting, parsing, and bundling are infrastructure, and infrastructure written in JS wastes everyone's CI minutes. ## The components | Tool | Replaces | Claim | Status | |---|---|---|---| | **Oxlint** | [[ESLint]] | 50-100x faster, 800+ rules, type-aware | Production-ready | | **Oxfmt** | [[Prettier]] | 30x faster than Prettier, 3x faster than Biome | Beta | | **oxc-parser** | SWC parsing | 3x faster than SWC | Stable | | **oxc-resolver** | enhanced-resolve | 28x faster | Stable | | **oxc-transformer** | Babel/SWC transpile | TS, JSX, framework support | Stable | | **oxc-minifier** | Terser | dead-code elimination | Alpha | Speed numbers are project-published, but the ESLint-vs-Oxlint gap is large enough that independent reports land in the same ballpark. ## How to think about it - **Oxlint is the entry point.** [[ESLint]]-compatible rule set, drop-in for most configs, and fast enough to run on every save and every commit without caching gymnastics. Type-aware linting removes the last reason to keep ESLint around for most projects. - **Oxc vs Biome**: same thesis (Rust, all-in-one), different strategy. Biome ships one integrated tool; Oxc ships composable libraries that other tools build on — its parser and resolver already sit inside other bundlers and toolchains. Oxc is infrastructure first, product second. - **The VoidZero picture**: Oxc supplies the low-level pieces for [[Vite]]'s Rolldown bundler era. Adopting Oxlint today is also a bet on that consolidation — now a Cloudflare-owned one. ## References - [Oxc Website](https://oxc.rs) - [Oxc on GitHub](https://github.com/oxc-project/oxc) ## Related - [[Rust]] — part of the same pattern: JS tooling migrating to Rust - [[Turbovec]] — unrelated domain, same "rewrite the hot path in Rust" wave - [[Vite]] — the flagship consumer of Oxc's foundations - [[ESLint]] · [[Prettier]] — what Oxlint and Oxfmt replace - [[Cloudflare]] — owner since June 2026
