<Tip>
  **Apps are currently part of a private beta program and are not publicly
  available.** <br />

Blocks are the core building components of frontend applications in Juo. Frontend applications utilize blocks to deliver custom experiences to subscribers, enabling rich, interactive user interfaces.

#### How blocks work

* **Custom Components**: Create custom UI blocks that can be published on the Juo platform
* **Portal Integration**: Blocks can be used in portals to build custom subscriber experiences
* **Reusable Components**: Blocks are reusable across different pages and contexts
* **Framework Agnostic**: Blocks work with various frontend frameworks

Blocks enable developers to:

* Create custom UI components for subscriber portals
* Build specialized subscription management interfaces
* Design branded experiences for merchants
* Extend the default portal functionality
