Desktop Browsers


SpeedCurve provides the following desktop browsers to test with:

Emulated Phones & Tablets


We use the device emulation built into Chrome DevTools so your tests run in the same environment as your local development. SpeedCurve provides nine emulated phones & tablets or you can build your own custom browsers and control settings like viewport size, device pixel ratio, connection speed and even packet rate loss. We also throttle the CPU to better emulate JS script performance.
