# About Self-Hosted App Extensions
  
Self-hosted extensions are app features that are hosted on an external platform and integrated with the Wix ecosystem using the [app dashboard](https://dev.wix.com/docs/build-apps/develop-your-app/app-dashboard-setup/about-the-app-dashboard.md). Your app can combine multiple extensions to provide a comprehensive service that spans across several user interfaces and backend capabilities. Browse the [extensions catalog](https://dev.wix.com/docs/build-apps/get-started/overview/how-apps-extend-wix.md#extension-catalog) to explore available extensions.

## Building and adding self-hosted extensions

Use your preferred development environment and tools to build your extension. Once it's ready, host it on any platform that exposes public, secure endpoints. Finally, add it to your app by configuring it in your [app's dashboard](https://dev.wix.com/docs/build-apps/develop-your-app/app-dashboard-setup/about-the-app-dashboard.md).
