Editorial take
Why it stands out
Biome is a high-leverage default for new web projects, but migrations should be staged. The risk is not price; it is whether your existing ESLint plugin assumptions map cleanly to Biome's rule model.

Tool profile
Fast formatter, linter, and web-project toolchain for JavaScript, TypeScript, CSS, JSON, HTML, and GraphQL.
Code formatting
Biome is a modern web-project toolchain that aims to replace several pieces of JavaScript quality tooling with one fast, cohesive binary. It formats and lints JavaScript, TypeScript, JSX, TSX, JSON, CSS, HTML, and GraphQL, provides contextual diagnostics, supports editor workflows through LSP, and is designed for speed without the dependency sprawl that often comes with formatter-plus-linter setups.
The editorial case for Biome is developer experience and operational simplicity. Instead of maintaining separate Prettier, ESLint, and related glue for common projects, teams can standardize on one tool that handles formatting and many linting rules with sane defaults. It is not a perfect replacement for every mature ESLint plugin ecosystem, so teams with deep custom lint rules should audit compatibility before switching everything at once.

Pricing snapshot
Biome is free and open source, dual-licensed under MIT or Apache-2.0. There is no official paid plan for the core formatter and linter; teams mainly pay through their own CI compute and migration effort.
