How Apps Extend Wix

Your app can add functionality to almost every part of the Wix ecosystem. It can display a widget on a Wix user’s site, add a page to a site’s dashboard, inject custom logic into a site’s backend service, and much more. Each specific type of functionality that an app can provide is called an extension. See the full list of available extensions below.

An app can contain multiple extensions that work together to expose its functionality across different user interfaces and backend services. For example, Wix’s FAQ app displays a customizable FAQ widget on a user’s site, and also has a dashboard page where the user can create and manage their FAQ categories, questions, and answers.

Most extensions are built using one of Wix’s development frameworks. However, some extensions only require configuration in the Wix Dev Center with no coding involved.

You can extend Wix’s frontend interfaces as well as various backend capabilities.

Frontend extensions include:

• Site extensions: Components that are added to a user’s site.
• Dashboard extensions: Components that are added to a user’s dashboard.

Backend extensions include:

• Service plugins: Business logic that’s injected into a site’s backend services.
• Schema plugins: Fields that are added to the database schemas of Wix business solutions.
• Notifications: Notifications sent to site owners.
