What is Biome?

Biome is a fast, all-in-one toolchain for web projects — it formats, lints, and assists your code in a fraction of a second. It is designed to replace Prettier and ESLint with a single, opinionated tool written in Rust.

Key Benefits

• Fast: Written in Rust, formats and lints in milliseconds
• All-in-one: Formatter + linter + import organizer in one tool
• Opinionated: Few options, no bike-shedding — like Prettier's philosophy
• Multi-language: JavaScript, TypeScript, JSX, TSX, JSON, CSS, GraphQL, Grit, HTML (experimental)
• Zero config: Works out of the box with sensible defaults
• Editor integration: First-party extensions for VS Code, IntelliJ, Zed
• CI ready: biome ci command optimized for CI pipelines
• Migration tools: biome migrate eslint and biome migrate prettier commands
• Plugin system: GritQL-based linter plugins for custom rules
