Ultracite

Ultracite v7.8.1 is a zero-configuration preset for Biome, ESLint, and Oxlint that provides hundreds of preconfigured linting and formatting rules for modern JavaScript/TypeScript projects. It runs via interactive CLI (`npx ultracite init`) and supports monorepos, AI agent integration (Claude Code, Copilot, Cursor, Gemini), and framework-aware rules. Requires peer dependencies oxfmt >=0.1.0 and oxlint ^1.0.0. Compared to alternatives like `eslint-config-prettier`, Ultracite is AI-ready and ships with a `doctor` command for diagnostics.
