## About

# Biome — Skill Overview

> **Source**: [biomejs.dev](https://biomejs.dev/) | [Getting Started](https://biomejs.dev/guides/getting-started/) | [Formatter](https://biomejs.dev/formatter/) | [Linter](https://biomejs.dev/linter/) | [CLI](https://biomejs.dev/reference/cli/) | [Configuration](https://biomejs.dev/reference/configuration/)

## 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
