Device emulation is an optional setting available for simple and scripted browser monitors. This setting simulates the viewport and capabilities of a mobile or tablet device using the emulation capabilities of DevTools in Chrome and Firefox.

Device emulation allows you to test a browser-based application using a simulated generic mobile or tablet device. Keep in mind:

-   This setting does not change the network, user agent, or device type being used to execute your synthetic monitor.
-   Device emulation does not allow you to install and test mobile applications.
