What is Ultracite v7?

Ultracite v7 is a production-grade, zero-configuration preset for ESLint, Biome, and Oxlint that helps teams and AI models write consistent, type-safe code. It eliminates the need for manual configuration by providing hundreds of pre-configured rules optimized for JavaScript and TypeScript frameworks. Trusted by companies like Vercel, Clerk, and ElevenLabs, Ultracite v7 can be initialized in seconds with a single command: npx ultracite@latest init.

Who it's for

• Frontend teams — who want to enforce consistent code style and quality across all team members without debating formatting rules.
• AI-assisted developers — who need their AI agents (Claude, Cursor, GitHub Copilot, and 40+ others) to produce code that matches the project's linting and formatting standards.
• Open-source maintainers — who manage thousands of contributions and need a reliable, zero-friction way to keep codebases clean and type-safe.

Key features

Zero-config by design

Ultracite v7 ships with hundreds of pre-configured rules tailored to your framework (React, Next.js, and more). You get a complete linting and formatting setup out of the box, with the option to customize when needed using a simple defineConfig import.

Designed for humans and AI

The preset ensures that both human developers and AI models produce code that follows the same consistent style. This eliminates code review friction and stops formatting debates, whether the code was written by a person or generated by an agent.

Agent and editor integration

Ultracite v7 supports 40+ AI agents for formatting rules and hooks, and automatically generates editor configuration files for format-on-save, auto-fixes, and TypeScript defaults. It works with VS Code, Cursor, and other popular editors, and includes MCP support for linting and formatting without running Ultracite locally.

What stands out

"Ultracite makes AI-generated code look like it was written by your best engineer — without any configuration."

This is the core edge: while other tools require teams to manually define rules and then teach their AI agents to follow them, Ultracite v7 bakes the rules into the agent workflow itself. It generates agent-specific rule files for Claude, Cursor, and others, so AI models automatically respect your project's linting and formatting standards from the first line of code they write.

Worth checking out if…

You're tired of configuring ESLint, Biome, or Oxlint from scratch, or you want your AI coding assistants to produce code that passes your team's quality checks without manual prompting. Ultracite v7 is also a strong fit if you manage multiple projects and need a consistent, zero-friction setup that works across editors, agents, and CI pipelines.
