title: Migrate from Prettier
description: Replace standalone Prettier setup with Ultracite while preserving formatting expectations and aligning the rest of your linting stack.
---

If you're already using Prettier and want to switch to Ultracite's preconfigured setup, this guide will help you migrate while preserving your formatting standards.

## Why Migrate to Ultracite?

- **Multiple Providers**: Choose between Biome, ESLint + Prettier + Stylelint, or Oxlint
- **Zero Configuration**: Ultracite provides highly configured presets for each provider
- **Editor Integration**: Built-in support for AI-powered editors (Cursor, Windsurf, GitHub Copilot)
- **Consistent Workflow**: Standardized setup across projects and teams
- **Maintained Rules**: Regular updates with new best practices

## Before You Start

Make sure you have:

- An existing project using Prettier
- Node.js 20+
- A Prettier configuration file (e.g., `.prettierrc`, `prettier.config.js`)

## Migration Options

### Option 1: Quick Migration (Recommended)

The fastest way is to run the [automatic setup script](/docs/setup#installation).

```package-install
npx ultracite init
```

This will:

- Prompt you to choose a linting provider (Biome, ESLint, or Oxlint)
- Install Ultracite and the necessary dependencies
- Create or merge your linter configuration with Ultracite's preset
- Merge your existing `.vscode/settings.json` with Ultracite's preset
- Enable `strictNullChecks` in your existing `tsconfig.json` files (skipped if your project has none)
- Set up editor integrations

If you switch to Biome or Oxlint (which have built-in formatters), Ultracite automatically removes the existing Prettier configuration. This will:

- Remove Prettier and any related dependencies
- Remove any Prettier configuration files

If you also select an editor to configure, your `.vscode/settings.json` is rewritten to match the new toolchain.

If you choose ESLint as your provider, Ultracite will configure Prettier alongside ESLint using Ultracite's preset.

### Option 2: Manual Migration

If you prefer more control over the process, follow the [Setup](/docs/setup#installation) steps and manually remove Prettier and its configuration files.

After the migration, restart your editor to ensure the new configuration is applied.
