Biome
Ultra-fast linter + formatter. Replaces ESLint + Prettier in a single tool, 100x faster.
Strengths
- Replaces ESLint + Prettier in a single Rust binary, 100x faster
- Zero config: biome check works out of the box on any TS/JS project
- Auto-fix: biome check --write fixes lint + format in one command
- Perfect CI integration: non-zero exit code on error, parseable output
Limitations
- Limited custom rules ecosystem, not yet 100% parity with ESLint plugins
- Some specialized ESLint rules (react-hooks, accessibility) missing
- Difficult adoption if project has complex existing ESLint configs
Best for
- New TypeScript/JavaScript projects without ESLint legacy
- CI/CD pipelines where lint gate speed is critical
