# Viewer

The **Viewer** will initially load the template marked as “Startup template” on the designer. The selected template will be marked with an asterisk (*). If no startup template is selected, an error message will be displayed when opening the **Viewer**:

The **Viewer** mode is intended for end users such as operators who are not going to design the interface, but instead, just use it. The key differences from the designer are:

- No Designer UI. Only contains a visual area that is created using the preselected startup template.
- Startup template will match the web browser size, regardless of the template’s original size.
- Only the startup template will be loaded, resulting in quicker loading.
- No selection, pan, or zoom interactions are permitted (however, the internal container zoom can be purposefully activated in the “Zoom & Pan” section).
- Holding the control key is not needed for launch events (click, mouse enter, etc.)

The Viewer can be launched from the **Web Vision** configuration page in the WebUI, as shown in the below image:

Alternatively, the **Viewer** can also be accessed by adding **/ui** to the **url** used to connect to the system. For example, **https://localhost:8444/ui.**
