Ultracite

Ultracite is a zero-config preset for Biome that provides a robust and opinionated linting and formatting experience. It's designed to ensure you, your team, and your AI agents are all writing code in perfect harmony, eliminating debates over style and streamlining code reviews.

Built in Rust, it delivers subsecond linting and formatting, making on-save checks feel seamless without interrupting your workflow. The preset enforces maximum type safety by default, catching type errors and preventing unsafe code patterns before they become a problem. It's an intuitive tool that automatically reformats code and fixes lint issues on save.

Key features include:

• Zero-Config by Design: Preconfigured with sensible defaults for Next.js, React, and TypeScript projects.
• Seamless Integration: Includes built-in scaffolding for Husky pre-commit hooks and lint-staged configuration.
• AI-Ready: Generates synchronized rule files for popular IDEs and AI agents like VS Code, Cursor, and Zed to maintain consistent style.
• Monorepo Support: Provides a unified toolchain configuration, eliminating duplicate config files across packages.
