Oxc Has a Free JavaScript Toolchain Written in Rust — Parser, Linter, Formatter, and Minifier 50x Faster

The JavaScript Tooling Speed Problem

ESLint: 10 seconds for a large project. Prettier: 5 seconds. Terser: 3 seconds for minification. Total: your CI pipeline spends 20 seconds just on linting and formatting.

Oxc (Oxidation Compiler) does all of this in Rust. 50x faster parser. 50x faster linter. One toolchain.

What Oxc Gives You

oxlint — Faster Than ESLint

npx oxlint

400+ lint rules. No plugins to install. No config required.

	ESLint	oxlint
1,000 files	10s	0.2s
Startup	1s	10ms
Memory	200MB	20MB

oxc-parser — Fastest JS/TS Parser

import { parseSync } from 'oxc-parser';

const result = parseSync('const x: number = 42;', {
  sourceFilename: 'test.ts',
});
// Returns ESTree-compatible AST

3x faster than SWC. 5x faster than Babel. 50x faster than TypeScript's parser.

oxc-transform — TypeScript/JSX Transform

import { transform } from 'oxc-transform';

const result = transform('test.tsx', '<div>Hello</div>');
// Strips types, transforms JSX — faster than SWC

oxc-minifier

Faster than Terser with comparable output size. Drop-in replacement for production builds.

oxc-resolver

Node.js module resolution algorithm in Rust. Used by Rspack and other bundlers.

Comparison

Tool	Parser	Linter	Formatter	Minifier
Traditional	Babel	ESLint	Prettier	Terser
Rust-based	oxc	oxlint	oxc-fmt	oxc-minifier
Speed gain	50x	50x	30x	5x

Quick Start

# Lint your project right now
npx oxlint

# Use as library
npm install oxc-parser oxc-transform

Why This Matters

JavaScript's tooling bottleneck is JavaScript itself. Oxc proves that rewriting core tools in Rust can make the entire development loop feel instant.
