Test your webcam, mic, speakers, keyboard and more in your browser
Free tests for the hardware on your desk: webcam, microphone, speakers, headphones, keyboard, mouse, game controller and screen. Each test runs in your browser, tells you what it found, and gives you a report you can paste into a support chat.
What you can count on
It stays on your device
The tests use features built into your browser. Your video, your voice and your keystrokes are processed on your own computer and are never uploaded.
A report you can paste anywhere
Each test ends with a short plain-text report of what worked, what didn't, and which browser and system you used. Paste it into a support chat, a return request or a forum post.
Fixes, not just a button
Every test explains what its result means and what to try next, including the settings to check on Windows 11 and macOS.
