**Biome** is a performant toolchain for web projects, it aims to provide developer tools to maintain the health of said projects.

**Biome is a [fast formatter](./benchmark#formatting)** for _JavaScript_, _TypeScript_, _JSX_, _JSON_, _CSS_ and _GraphQL_ that scores **[97% compatibility with _Prettier_](https://console.algora.io/challenges/prettier)**.

**Biome is a [performant linter](https://github.com/biomejs/biome/tree/main/benchmark#linting)** for _JavaScript_, _TypeScript_, _JSX_, _JSON_, _CSS_, and _GraphQL_ that features **[more than 340 rules](https://biomejs.dev/linter/javascript/rules/)** from ESLint, typescript-eslint, and [other sources](https://github.com/biomejs/biome/discussions/3).
It **outputs detailed and contextualized diagnostics** that help you to improve your code and become a better programmer!

**Biome** is designed from the start to be used [interactively within an editor](https://biomejs.dev/guides/editors/first-party-extensions/).
