Hardware Test Online is a free toolkit for testing your devices directly in the browser. You can check your webcam, microphone, speakers, keyboard, mouse, gamepad, touch screen, refresh rate, dead pixels, vibration, gyroscope, and more. No install, no signup, and no account required. It is useful when setting up a new laptop, debugging peripherals, checking a second-hand device, preparing for a video call, or quickly verifying that hardware works before blaming the app.
