# Live View and Static Frontend

This feature allows you to preview real-time output from your applications directly within Hub. If an application includes a
static frontend, Hub makes it available through its hosted frontend path. If no custom frontend is shipped, Hub opens the default
visualizer instead.

> **Open Frontend**
> To open an application's frontend, navigate to:
> **Devices → Select a Device → Apps (Tab) → Select a Running Application → Open Frontend**
> .

> **Default Visualizer**
> If no frontend is shipped with the app, the
> **default visualizer**
> will open instead. This is the recommended default rendering path for remote portals and Hub-based viewing, especially when you
need more than raw video such as overlays, detections, or richer outputs.

> **Customer portals**
> For customer-facing products, the recommended architecture is still backend-mediated: your backend requests the connection
payload from Hub, and your frontend uses that returned payload to connect. See
