Plug and Check

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.
