A clearer way to check your device

CheckMyDevice helps you test the parts of a device that a browser can reach, understand what happened, and decide what to try next.

Evidence before confidence

A working animation is not a diagnosis. Our checks distinguish a received signal, a user observation, an unavailable capability and an unsuccessful attempt. We do not assign a device health percentage or claim to certify hardware.

Built for everyday decisions

Check your microphone before a meeting, inspect a new monitor within its return window, or run several tests before buying a used laptop. A downloaded report provides a record of this session, with limitations attached.
