About DeviceCheck

DeviceCheck is a browser-based device testing hub built to make everyday hardware checks fast, clear, and accessible. It brings keyboard, mouse, gamepad, screen, microphone, webcam, and speaker tools together in one consistent interface, without requiring an account or software installation.

What DeviceCheck helps you do

The tools are designed for quick checks after connecting new hardware, troubleshooting a device that behaves unexpectedly, confirming that a used device works, or gathering clear information before contacting support. Each test focuses on live browser data and explains the limits of what can be measured.

How the tests work

Most interactions are processed directly in your browser. Camera and microphone tools request permission only after you start them. DeviceCheck displays the signals and settings exposed by the browser and does not invent measurements that the browser cannot provide.

Important limitations

Browser tests are useful for initial diagnosis, but they do not replace professional calibration equipment, manufacturer utilities, electrical inspection, or repair. Results can vary with the browser, operating system, drivers, permissions, and connected hardware.
