About OnlineHardwareTest
What we do
OnlineHardwareTest is a set of free diagnostics for the devices you use every day: keyboards, mice, controllers, screens, cameras, speakers, microphones and network connections. Each test opens instantly in your browser and gives you a clear result.
How the tests work
The tests use standard browser technologies such as Web Audio, Media Devices, Pointer Events, the Gamepad API and WebGL. They read the same signals an app on your computer would see. Measurements are calculated on your device; camera and microphone streams never leave it.
Who it is for
Gamers checking a new mouse or controller, remote workers preparing for a call, people buying a second-hand laptop or monitor, and IT staff who need a quick check without installing software.
Accuracy
Browsers limit some measurements for privacy and security. Where a result is an estimate, the tool says so. For warranty claims, use the manufacturer's own diagnostic tool alongside ours.
