Device tests

Test your webcam, microphone, keyboard and screen for dead pixels, right in the browser. Nothing is recorded or uploaded.

• Webcam TestCheck that your camera works before a call: live preview, resolution and frame rate, camera picker, mirror view and snapshot. Nothing is recorded.
• Microphone TestCheck your microphone: live level meter and waveform, clipping warning, echo and noise suppression toggles, and a 5-second recording to play back.
• Keyboard TesterPress every key and watch it light up on a full-size ANSI or ISO diagram, with key codes, rollover count and stuck-key detection.
• Dead Pixel TestFill the screen with solid colours to spot dead, stuck or hot pixels and backlight bleed, with an optional stuck-pixel fixer (opt-in, flashing).
