Biome is a fast, Rust‑based toolchain for web projects that provides code formatting and linting. It can be used via a command‑line interface or as a language server protocol (LSP) server.

Use cases

format JavaScript, TypeScript, JSX, and TSX files
lint JavaScript and TypeScript codebases
enforce style rules across JSON, HTML, CSS, and GraphQL files
run a quick code quality check in CI pipelines
auto‑format malformed code while editing
integrate a fast formatter into any editor via LSP

When to choose

You need a high‑performance formatter and linter that works out‑of‑the‑box without Node.js.
You want a single tool that can handle multiple web languages (JS/TS/HTML/CSS/JSON/GraphQL).
You prefer a Rust binary for low overhead and fast execution in CI.

When to avoid

You require highly custom lint rules that are not provided by Biome.
You need deep integration with a specific IDE that only supports other formatters.
Your project relies on a formatter written in the same language as the project (e.g., Prettier for Node.js).
