Keyboard Tester

Test every key on your keyboard online and detect dead keys.
Test & Key Stats

Press any key on your real keyboard - the virtual one mirrors it in real time.

Everything runs locally in your browser - no keystrokes are recorded, stored or sent anywhere. Browser shortcuts (like Ctrl+T) are left alone; plain keys are captured so the page doesn’t scroll or refresh while you test.

Tool Introduction

The Keyboard Tester highlights each key on a virtual keyboard the moment you press it, so a dead or sticky key is impossible to miss. It tracks every keystroke - including which physical key fired, its key code and location - and keeps a running list of everything you have tested so far.

Use it when a laptop key stops responding, when a mechanical keyboard feels mushy, or simply to verify a new board before the return window closes. Works with standard, laptop and multimedia keyboards, and nothing you type is recorded.
