Biome JS

Fast formatter and linter for web projects, built as a unified toolchain to replace Prettier and ESLint. Covers JavaScript, TypeScript, JSX, TSX, JSON, HTML, CSS, and GraphQL with a single command, delivering format and lint output in a fraction of the time of traditional setups.

Used by organizations such as AWS, Cloudflare, Coinbase, Microsoft, and Vercel. Biome stands out as a drop-in alternative: it achieves high compatibility with Prettier formatting, bundles hundreds of rules that mirror ESLint and TypeScript ESLint, and runs significantly faster because it is implemented in Rust.

Key capabilities:

• Single command for format, lint, and diagnostics across the web stack
• 462+ lint rules with safe fixes and contextual diagnostics
• Zero configuration by default, with config options for advanced needs
• LSP and editor extensions for real-time feedback and format-on-save
• Formats malformed code and integrates with CI pipelines

Teams adopt Biome to cut CI time, unify formatting and linting in one tool, and avoid juggling multiple dependencies. It fits into existing workflows via the CLI or editor plugins, making migration from Prettier and ESLint straightforward.
