Biome formats and lints your code in a fraction of a second.

Biome supports JavaScript, TypeScript, JSON, and CSS. It aims to support all main languages of modern web development.

Biome has sane defaults and requires minimal configuration. Biome helps you as much as possible by displaying detailed and contextualized diagnostics. Read more about our project philosophy.

Biome unifies functionality that has previously been separate tools. Building upon a shared base allows us to provide a cohesive experience for processing code, displaying errors, parallelizing work, caching, and configuration.

Biome is designed to eventually replace Babel, ESLint, webpack, Prettier, Jest, and others.

Biome has first-class IDE support, with a sophisticated parser that represents the source text in full fidelity and top-notch error recovery.

Biome is MIT licensed and moderated under the Contributor Covenant Code of Conduct.
