Biome vs ESLint (2026): Which JavaScript Linter Should You Choose?

Quick Answer

Biome is the fast-rising Rust-based alternative — replaces both ESLint AND Prettier in a single tool, 10-100x faster linting/formatting, and zero configuration to get started. ESLint is the established standard — largest ecosystem of plugins and rules, highly configurable, and every developer knows it. For new projects, Biome is increasingly the default. For projects with complex ESLint rules or plugins not yet in Biome, ESLint remains necessary.

Feature Comparison

Feature	Biome	ESLint
Language	Rust — extremely fast	JavaScript/Node.js
Speed	10-100x faster than ESLint + Prettier	Slower — especially on large codebases
Formatting	Built-in (replaces Prettier)	Requires Prettier separately
Configuration	biome.json — simple defaults	.eslintrc — complex but powerful
Plugin Ecosystem	Limited — growing (no React rules yet)	Massive — eslint-plugin-react, unicorn, etc.
TypeScript	First-class TS support built-in	@typescript-eslint plugin required
Rules Count	250+ rules	1,000s via plugins
Best For	New projects, speed-focused teams	Complex configs, React rules, existing projects

Who Should Choose What?

Choose Biome if:

You are starting a new project and want one tool instead of ESLint + Prettier, with dramatically faster CI lint checks. Biome's zero-configuration defaults are sensible, and its 250+ lint rules cover most JavaScript/TypeScript best practices. The speed improvement is especially noticeable in CI pipelines and pre-commit hooks.

Choose ESLint if:

You need React-specific rules (eslint-plugin-react-hooks, jsx-a11y), have a complex existing ESLint configuration, or require custom rules that Biome does not yet support. ESLint's plugin ecosystem with thousands of rules remains unmatched. For teams with accessibility requirements (eslint-plugin-jsx-a11y) or specific framework rules, ESLint is still necessary.

FAQ

Is Biome or ESLint better for JavaScript linting?

Biome is better for speed and simplicity — replaces ESLint + Prettier in one tool, 10-100x faster. ESLint is better for ecosystem depth and complex configurations. New projects increasingly use Biome; existing projects with complex ESLint configs should evaluate migration effort.

Is Biome faster than ESLint?

Yes — dramatically. Biome is written in Rust and is 10-100x faster than ESLint + Prettier combined. CI pipelines that took minutes with ESLint can complete in seconds with Biome. The tradeoff is fewer rules and no React-specific plugin support yet.
