Browsers & devices
The desktop browsers and emulated phones and tablets – as well as default connection bandwidths – available in your Synthetic settings
Desktop browsers
SpeedCurve provides the following desktop browsers to test with:
- Chrome
- Firefox
- Internet Explorer 11
Our default desktop test profiles use a viewport size of 1280x800 with a pixel ratio of 1.0. They use the "cable" network setting, and don't apply any CPU throttling.
We update our browser versions during a scheduled test agent update every 3 months. You can see the browser version that was used to run a test at the top of each test result page :
Emulated phones & tablets
We provide preconfigured emulated phones and tablets. You can also build your own custom browsers and control settings like viewport size, device pixel ratio, connection speed, and even packet loss.
Below are the default emulated phones and tablets, along with their network speed and viewport settings. Most of the devices use emulated CPU throttling.

Connection bandwidth
The connection for our tests is throttled to emulate the average bandwidth of users. When adding a Custom Browser you can adjust the connection speed to emulate slower mobile or faster fiber connections.
