Check the hardware this browser can reach — camera, microphone, speakers, keyboard, screen, and controller. Every permission is asked only when you press the button, and everything stays on this device.
- Webcam test
See yourself, read the track's real settings, switch cameras — permission only on your click.
- Microphone test
A live level meter over the real stream — nothing recorded, permission only on your click.
- Speaker test
Left, right, both — three synthesized tones; your ears do the checking.
- Keyboard test
Press keys in the zone — see key, code, location, and modifiers exactly as the browser sees them.
- Gamepad test
Buttons with real names under standard mapping, live axes, an explicit vibration pulse.
- Dead pixel test
Five solid colors, full screen — your eyes are the detector, and the page says so.
- Refresh rate
A four-second frame-timestamp sample — median-interval Hz with every caveat kept honest.
- Screen recorder
Record your screen, a window, or a tab — permission on your click, every resource released on stop, output verified.
