Device & Network Tests
Check your camera, microphone, screen, keyboard, mouse, controller and connection — free, in your browser.
Test your hardware without installing anything
These quick checks help you spot problems before they ruin a meeting, a class or a ranked match. Start with the webcam test and mic test before calls, use the dead pixel test and screen resolution checker on a new monitor or phone, and confirm every key and button with the keyboard tester, mouse button tester and gamepad tester.
For your connection, see what is my IP and run the internet speed test. Gamers can then measure clicks per second in the CPS test and reflexes in the reaction test.
