# Determine Which CLI Your Project Uses


The Wix CLI is a unified tool for both Wix apps and Wix-managed headless projects.

If you're working on an existing app project, you can identify which CLI it uses by checking a few key indicators.

## Check your package.json

Look for `@wix/astro` in your project's `devDependencies`.

```json
{
  "devDependencies": {
    "@wix/astro": "^2.0.0"
  }
}
```

## Check for extensions.ts file

Look for an `extensions.ts` file in your project's `src` folder.

```
src/
├── extensions.ts
└── ...
```

If your project has these indicators, then it uses the Wix CLI documented in this reference.

If your project doesn't have these indicators, your app project uses the [Legacy Wix CLI for Apps](https://dev.wix.com/docs/wix-cli/legacy-clis/legacy-wix-cli-for-apps/about-the-legacy-wix-cli-for-apps.md).
