Biome vs ESLint (2026): Which JavaScript Linter Should You Choose?
By Alex Chen, SaaS Analyst · Updated April 11, 2026 · Based on benchmark testing across real projects
30-Second Answer
Choose Biome if you want one Rust-based tool that replaces both ESLint AND Prettier — 10-100x faster, zero config, and ideal for new projects. Choose ESLintif you need the massive plugin ecosystem (React hooks, JSX accessibility, custom rules) or have complex existing configs. Biome wins 4-2 overall, but ESLint's ecosystem depth remains unmatched for complex projects.
Our Verdict
Biome
- 10-100x faster than ESLint + Prettier
- Replaces both linter and formatter in one tool
- Zero-config sensible defaults
- 250+ rules vs ESLint's 1,000s
- No React-specific plugin rules yet
- Smaller community and ecosystem
Deep dive: Biome full analysis
Features Overview
Biome (formerly Rome) is a Rust-based toolchain that replaces ESLint + Prettier in a single binary. The speed difference is dramatic — a codebase that takes 2 minutes to lint with ESLint may take 5 seconds with Biome. The zero-config approach means you can run "biome check ." on any project immediately without configuring anything. First-class TypeScript support is built in, no plugins required. Biome is increasingly adopted by companies like Ubisoft, Shopify, and Discord.
Installation & Setup
| Step | Command | Notes |
|---|---|---|
| Install | npm install --save-dev @biomejs/biome | Single dependency |
| Init | npx biome init | Creates biome.json with defaults |
| Run | npx biome check . | Lint + format in one command |
Who Should Choose Biome?
- Teams starting new JavaScript/TypeScript projects
- CI pipelines where lint speed matters (saves minutes per build)
- Developers tired of ESLint + Prettier configuration conflicts
- Projects that want one tool instead of multiple dependencies
ESLint
- Massive ecosystem — 1,000s of rules via plugins
- React, accessibility, and framework-specific rules
- Every JS developer already knows it
- 10-100x slower than Biome
- Complex configuration (.eslintrc hell)
- Requires Prettier separately for formatting
Deep dive: ESLint full analysis
Features Overview
ESLint is the established JavaScript linting standard with the largest plugin ecosystem in existence. eslint-plugin-react-hooks enforces React Hook rules, eslint-plugin-jsx-a11y catches accessibility issues, and @typescript-eslint provides deep TypeScript analysis. Pre-built configs like Airbnb, Standard, and Google give teams instant code style enforcement. Over 30 million weekly npm downloads make it the most-used JS tool by far.
Common Configuration Stack
| Package | Purpose | Weekly Downloads |
|---|---|---|
| eslint | Core linter | 30M+ |
| @typescript-eslint | TypeScript support | 15M+ |
| eslint-plugin-react | React-specific rules | 12M+ |
Who Should Choose ESLint?
- Projects needing React Hook rules (eslint-plugin-react-hooks)
- Teams with complex existing ESLint configurations
- Accessibility-focused projects using eslint-plugin-jsx-a11y
- Organizations requiring custom lint rules not in Biome
Side-by-Side Comparison
| Category | Biome | ESLint | Winner |
|---|---|---|---|
| Speed | 10-100x faster (Rust-based) | Slower — especially on large codebases | ✔ Biome |
| Formatting | Built-in (replaces Prettier) | Requires Prettier separately | ✔ Biome |
| TypeScript | First-class built-in support | @typescript-eslint plugin required | ✔ Biome |
| Configuration | biome.json — simple, sensible defaults | .eslintrc — complex but powerful | ✔ Biome |
| Plugin Ecosystem | Limited — growing (250+ rules) | Massive — 1,000s of rules via plugins | ✔ ESLint |
| Community Size | Growing rapidly | 30M+ weekly npm downloads | ✔ ESLint |
| Pricing | Free & open source | Free & open source | — |

Which do you use?
Who Should Choose What?
→ Choose Biome if:
You're starting a new project and want one tool instead of ESLint + Prettier with dramatically faster CI checks. Biome's zero-config defaults 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 Biome doesn't yet support. ESLint's plugin ecosystem with thousands of rules remains unmatched for accessibility and framework-specific requirements.
→ Consider neither if:
You're writing a small script or prototype — linting adds overhead you don't need. For personal projects under 500 lines, TypeScript's built-in compiler checks may be sufficient.

Frequently Asked Questions
Editor's Take
I switched my last three projects to Biome and haven't looked back. The CI time savings alone justified it — our lint step went from 90 seconds to 3 seconds. But I still keep ESLint on our React projects for the hooks rules. My advice: use Biome everywhere you can, ESLint where you must.
