About Test My Device
Test My Device is a free, browser-based collection of simple computer peripheral testing tools. It's designed for students, remote workers, gamers and anyone who wants to check basic mouse, keyboard and audio functionality. These checks can reveal common input and playback issues, but cannot diagnose every hardware fault.

Frequently Asked Questions
Is Test My Device free?
Yes. The mouse, keyboard, headset and microphone tests are free to use.
Do I need to install anything?
No. Test My Device works in compatible web browsers without installing an app.
Can I test a gaming mouse or mechanical keyboard?
