Ultracite
Ultracite is a zero-configuration linter preset that helps humans and agents write consistent code.
Ultracite is a zero-config preset for Oxlint, Biome, and ESLint that helps humans and agents write consistent, type-safe code. It provides strict linter and formatter defaults out of the box, with every rule still yours to override. The tool writes rules files for 41 agents and hooks that fix files edited in tools like Cursor, Windsurf, and GitHub Copilot. It automatically generates editor files for format on save, auto-fixes, and TypeScript defaults. It is designed for developers working with JavaScript and TypeScript projects who want to reduce code review friction.
