# Device tools

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.
](/device/webcam)
- [Microphone test

A live level meter over the real stream — nothing recorded, permission only on your click.
](/device/microphone)
- [Speaker test

Left, right, both — three synthesized tones; your ears do the checking.
](/device/speakers)
- [Keyboard test

Press keys in the zone — see key, code, location, and modifiers exactly as the browser sees them.
](/device/keyboard)
- [Gamepad test

Buttons with real names under standard mapping, live axes, an explicit vibration pulse.
](/device/gamepad)
- [Dead pixel test

Five solid colors, full screen — your eyes are the detector, and the page says so.
](/device/dead-pixel)
- [Refresh rate

A four-second frame-timestamp sample — median-interval Hz with every caveat kept honest.
](/device/refresh-rate)
- [Screen recorder

Record your screen, a window, or a tab — permission on your click, every resource released on stop, output verified.
](/device/screen-recorder)
