Summary
A unified linting and formatting wrapper that supports Biome, ESLint, or Oxlint under one interface. Ships with 200+ preconfigured rules and framework-specific presets for React, Next.js, Vue, and Svelte, so you skip the setup bikeshedding. The Biome default is genuinely fast (Rust-based, 10-100x faster than ESLint), though you trade ecosystem maturity for speed. Version 7 added multi-provider support and an MCP server for AI editor integration. Best for new TypeScript projects or teams tired of maintaining ESLint configs. If you have deep ESLint plugin dependencies or need advanced CSS linting, the migration effort might not pay off. The interactive doctor command and preset migrations are thoughtful touches.
