Test your mic, camera and keys in seconds.

Does my device work? One click tells you

DeviceKite is a small lab for the things you plug in, hold and talk into. Each test answers one question fast, then tells you what the numbers mean.

• The mic test shows your level in dBFS, your room noise and a recording you can play back.
• The webcam test compares the resolution and frame rate your camera claims with what it really delivers.
• The webcam and mic test is a one-click check before a call.
• The speaker test plays left, right, a sweep and bass tones for speakers and headphones.
• The keyboard test lights up every key on a layout for your language. The mouse test catches unwanted double clicks.
• The gamepad tester measures stick drift, and the dead pixel test fills your screen with solid colours.

All of them are in device tests.

Skill tests for quick hands

When the gear checks out, test yourself. The reaction time test measures how fast you respond in milliseconds. The CPS test and the spacebar clicker count clicks and presses per second. The aim trainer times your hits, and the typing test measures words per minute. Your bests stay in your browser; there is no account and no leaderboard. More in skill tests.

What stays on your device

Everything. The microphone and camera open only when you press a start button, never on page load, and a Stop button releases them so the system indicator turns off. Sound and video are analysed in your browser and never uploaded. A mic recording lives in the tab’s memory until you download it or reload. Skill results are saved in your browser only, and you can clear them at any time.

When something doesn’t work

A failed test is a good start: it tells you whether the problem is the device, the system or an app. Our guides take it from there with exact menu names, for example microphone not working on Windows, allowing the mic and camera in your browser or laptop camera not working.
