Ultracite is free and open source — and always will be. The CLI, presets, and all configurations are available at no cost for individuals and teams of any size.

Ultracite Cloud is our paid offering for teams who want to automate and scale their code quality management. It automatically lints your GitHub repositories and fixes issues using AI. Connect your repos once, and Ultracite will keep your code clean without any manual intervention.

Features

Automated PR Reviews

When you comment @ultracite review on a pull request, Ultracite automatically:

1. Checks out your PR branch in a secure sandbox
2. Runs ultracite fix to auto-fix what it can
3. Uses Claude Code to fix remaining issues that require more context
4. Commits the fixes directly to your PR branch
5. Leaves a comment summarizing what was fixed

Scheduled Lint Runs

Ultracite runs daily on your default branch to catch issues that slip through:

1. Clones your repository into a secure sandbox
2. Runs ultracite fix to auto-fix issues
3. If issues remain, uses Claude Code to fix one issue at a time
4. Creates a pull request with the fixes and a generated changelog

Dashboard

The dashboard gives you visibility into:

• All connected repositories
• Lint run history and status
• Issues found and fixed
• Pull requests created

How It Works

Secure Sandboxes

All linting and fixes run in isolated sandbox environments. Your code is cloned, processed, and the sandbox is destroyed — we never store your source code.

AI-Powered Fixes

When ultracite fix can't auto-fix an issue, Ultracite uses Claude Code to understand the context and apply intelligent fixes. This handles complex issues like:

• Refactoring to reduce cognitive complexity
• Adding missing accessibility attributes
• Fixing type errors that require code changes

Pull Request Integration

Ultracite creates focused pull requests with:

• Clear commit messages explaining each fix
• Auto-generated changelogs describing what changed
• Links back to the Ultracite dashboard

Permissions

The Ultracite GitHub App requires:

• Read access to code and metadata
• Write access to code and pull requests
• Webhook events for pull request and installation events

Ultracite only accesses repositories you explicitly enable.
