Keyboard Tester FAQ
What is this online keyboard tester?
This online keyboard tester lets you check keyboards across multiple layouts in one place. It works as a simple keyboard key tester so you can see whether every key registers correctly before you rely on your keyboard for work, gaming, or remote support.
As you press letters, numbers, modifiers, arrows, and numpad keys, the matching keys on the visual keyboard highlight so stuck, missing, or double-firing inputs are easy to spot.
How do I use the layout and variant selectors?
Start by choosing a layout family from the Layout dropdown, such as QWERTY, QWERTZ, AZERTY, Cyrillic, Greek, Asia, or Arabic. This loads the correct keyboard shape and key positions for that family.
From there you can follow the links in the navigation bar to open layout-specific tester pages like US QWERTY, German QWERTZ, French AZERTY, Russian Cyrillic, or Japanese. Each layout page mirrors the exact operating system mapping for that regional keyboard.
How do the highlight modes and numpad toggle work?
Every layout tester includes three highlight modes so you can inspect your keyboard in different ways: Live highlight shows keys only while they are held, Stay lit keeps keys highlighted until you reset them, and Find missing starts with every key primed so that missing inputs stand out at the end.
The numpad toggle lets you show or hide the numpad column so the visual keyboard matches your hardware, whether you are testing a full-size board, a tenkeyless model, or a compact laptop keyboard.
Can I use this to see if all my keys are working?
Yes. This keyboard tester is designed to show you at a glance which keys work, which are stuck, and how many keys register at the same time. You can hold down several keys at once to see rollover behavior and detect ghosting issues on older or low-end keyboards.
If some keys never highlight even when pressed individually, they may be blocked by your browser or operating system, or the keys themselves may be physically faulty.
Which layouts and devices are supported?
The tester supports QWERTY, QWERTZ, AZERTY, Cyrillic, Greek, Asia, and Arabic layout families, with many regional variants for languages and countries around the world. It works in modern browsers on Windows, macOS, Linux, and many Chromebooks.
You can use it with built-in laptop keyboards, external USB or Bluetooth keyboards, and many gaming keyboards. Some media keys, Fn-layer shortcuts, and system-reserved key combinations may not appear because the operating system does not send those events to the browser.
When should I use this page instead of a specific layout tester?
Use this page when you are not sure which layout your keyboard uses or when you want a quick overview across layout families. Once you know whether your keyboard is QWERTY, QWERTZ, AZERTY, Cyrillic, Greek, Asia, or Arabic, follow the links to open the matching layout-specific tester page for deeper checks.
Layout-specific pages mirror the exact positions and legends for that mapping, which is ideal when you need to test language-specific characters, diacritics, or regional shortcuts.
Is this keyboard tester safe and private to use?
Yes. All key detection happens locally in your browser, and keystrokes are used only to update the visual keyboard, counters, and highlight modes.
No key presses are stored or sent to our servers, but you should still avoid typing sensitive passwords while testing, just as a best practice.
