Test your computer hardware in the browser

Start with the device you want to check. Keyboard and mouse tests respond to your input immediately. Camera and microphone tests start only after you choose Start and grant the required browser permission.

Understand what a browser test can tell you

These tools show the input and output available to a webpage. Operating-system shortcuts, browser permissions and device support can affect results. A passing sample does not certify hardware health; each test explains its measurement limits.

Designed for Windows PCs, laptops and MacBooks. Availability of individual features depends on your browser and connected hardware.
