# About Frontend Modules

> **Note:** Frontend modules are for sites built in Wix Studio or Wix Editor. For Studio Two sites, use the [Site SDKs](fallback::https://dev.wix.com/docs/sdk/site-sdk/introduction) instead.

Frontend modules in the Wix JavaScript SDK provide frontend APIs for interacting with Wix sites and their features directly from the browser. They require Wix hosting and aren't available for external hosting environments.

Some functionality may still require using Velo APIs alongside the SDK. For functionality not yet supported by SDK frontend modules, refer to the [Velo to SDK API Mapping](fallback::https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/develop-with-the-sdk/velo-to-sdk-api-mapping) documentation.

Frontend modules are intended for:

- **Extending Wix sites**: Developers building custom functionality within a Wix site environment.
- **Wix app development**: Developers creating site extensions for apps that run within a Wix site environment.

<blockquote class="important">

**Important:** Frontend modules are **not** compatible with Wix Headless projects. For headless implementations, use the appropriate backend modules.

</blockquote>

## Available environments

Frontend modules can be used in the following environments:

- **Site**: For code running on live Wix sites.
- **Dashboard**: For custom dashboard pages.
- **Editor**: For extending the Wix Editor functionality.
