WHY DEVICETEST?
Simple tools for everyday hardware problems.
Supported tests process device input in your browser and request permissions only when required.
Use DeviceTest on desktops, laptops, tablets and supported mobile browsers.
DEVICE DIAGNOSTICS
Check your hardware without installing software.
DeviceTest provides simple browser-based diagnostic tools for common hardware problems. Depending on your device and browser, you can test mouse buttons, double clicks, keyboard input, controllers, microphone levels, camera access, touch input, screen colors and speaker output.
Browser tests have limits: they can show what the browser detects, but they cannot directly inspect every hardware component, driver, firmware setting or operating-system problem.
Frequently asked questions
Is DeviceTest free?
Yes. The browser-based tests are free to use and do not require a download.
Do I need to install anything?
No. DeviceTest is designed to run in a modern web browser. Camera and microphone tools require browser permission.
Can DeviceTest prove that my hardware is completely working?
No. A browser test can confirm that supported input or media is being detected, but it cannot diagnose every hardware, driver or operating-system problem.
Which devices can I test?
You can test supported mice, keyboards, controllers, microphones, webcams, touchscreens, displays, speakers and general device information through the available tools.
