Frequently asked questions
Is DeviceTest free?
Yes. DeviceTest's browser-based device tests are free to use and do not require a download.
Does DeviceTest download anything?
No. The tests are designed to run directly in your browser. Camera and microphone tests require permission from your browser.
Can a browser test prove that my hardware is completely working?
No. Browser tests can show whether supported device inputs are being detected, but they cannot diagnose every hardware, driver or operating-system problem.
Why does my microphone or webcam need permission?
Modern browsers protect camera and microphone access. You must explicitly allow a website to use these devices.
What devices can I test?
DeviceTest currently provides online tests for mice, keyboards, microphones, webcams and gamepads/controllers.
