Device emulation

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 Chrome DevTools.

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.


  • Chrome 100+ runtimes only
  • Private locations must use job manager version 225 or higher and synthetics-node-browser-runtime version 1.1.98 or higher
