> For AI agents: see the complete documentation index at [llms.txt](/llms.txt).

The TEN Cloud Store is a centralized repository for TEN packages, similar to Google Play Store or Apple App Store. It provides a curated collection of extensions, apps, and system components that you can download directly into your TEN applications to accelerate development and add functionality.

## Available package types [#available-package-types]

The TEN Cloud Store offers the following types of packages for download:

* **App**: Complete TEN applications ready for deployment
* **Extension Group**: Collections of related extensions that work together
* **Extension**: Individual components that add specific functionality
* **System**: Core framework components and runtime services
* **Protocol**: Communication protocols for inter-extension messaging

## Package information [#package-information]

The cloud store maintains detailed metadata for each TEN package to ensure proper dependency resolution and version management:

* **Package type**: Identifies the category of package: `extension`, `app`, `extension_group`, `protocol`, or `system`.

* **Package name**: Unique identifier for the package, such as `builtin_extension` or `audio_processor`.

* **Package version**: Version number following [semantic versioning (semver)](https://semver.org/) standards, such as `3.0.0`.

* **Dependencies**: Array of required packages with their version constraints:
  * **Type**: Package category matching the supported types above
  * **Name**: Exact package identifier
  * **Version**: Version requirement using semver syntax, such as `~3.0.0` or `^2.1.0`

This structured metadata enables automatic dependency resolution and ensures compatibility when integrating packages into your TEN applications.
