Why Use Our Keyboard Tester?
7 Keyboard Layouts
Test with Windows Full (104-key), TKL, 75%, 65%, 60%, Mac Full with numpad, or Mac compact layout - just pick the one that matches your keyboard.
Visual Key Highlighting
Each key lights up orange while held and turns green once released, so you can see exactly which keys have been tested and which have not.
Progress Tracking
A live progress bar shows how many keys you have tested out of the total for your selected layout, counting up to 100% when all keys pass.
Last Key Display
The exact key name and KeyboardEvent.code are shown for every press, making it easy to identify keys that register under unexpected codes.
Windows and Mac Support
Mac layouts correctly show fn, control, option, and command keys. Windows layouts show Ctrl, Win, Alt, and Menu keys in their proper positions.

Frequently Asked Questions
How do I test my keyboard?
Select your keyboard layout from the options above, click Start Testing, then press each key on your physical keyboard. Keys turn green when working and the progress bar tracks how many you have tested.
What keyboard layouts are supported?
Windows Full (104-key with numpad), Windows TKL (87-key), Windows 75%, Windows 65%, Windows 60%, Mac Full with numpad, and Mac compact for Magic Keyboard and MacBook keyboards.
Why does a key not light up when I press it?
Some keys like PrintScreen, ScrollLock, and certain Fn combinations are intercepted by the OS before reaching the browser. This is a browser limitation, not a keyboard issue.
What is the difference between a dead key and a stuck key?
A dead key sends no signal at all and will never light up regardless of how hard you press it. A physically stuck or sticky key may register intermittently or stay pressed without releasing.
What is TKL?
TKL stands for Tenkeyless. It is a keyboard size that removes the numpad on the right side while keeping the full function row, navigation cluster, and arrow keys. TKL keyboards are popular for gaming and desk space savings.
Is the keyboard tester free?
Yes. Completely free with no sign-up, no download, and no extensions required. It works in any modern browser.
