Why this site exists
When a key stops registering or a meeting app cannot hear you, the first question is always the same: is it the hardware or the software? MyGearCheck exists to answer that question in seconds. Every test uses native browser APIs, so you can check a keyboard, mouse, microphone, webcam, display or game controller without installing anything or creating an account.
How the tests work
Each test listens to the standard events and streams your browser already exposes, then mirrors them on screen: keypresses light up a virtual keyboard, your mic level moves a live meter, your camera shows a real-time preview. Because everything happens on your own device, nothing you press, say or show ever leaves the tab. You can read exactly how that works in the privacy policy.
