Frequently Asked Questions

What does this keyboard test check?
This keyboard test detects every key press on your keyboard, identifies stuck or broken keys, measures n-key rollover (how many keys can be pressed simultaneously), and checks for ghosting issues. All testing runs entirely in your browser.
How do I find broken or stuck keys?
Press each key on your keyboard and watch the visual keyboard layout. Keys turn blue when pressed and green when released. If a key stays blue for more than 3 seconds, it may be stuck. Keys that never highlight when pressed may be broken or not registering.
Does this work on laptops and external keyboards?
Yes, the test works with any keyboard connected to your computer including laptop keyboards, external USB keyboards, wireless keyboards, and mechanical keyboards. The visual layout shows a standard ANSI 104-key format but will detect keys from any layout.
Which browsers are supported?
The keyboard test works in all modern browsers including Chrome, Firefox, Safari, and Edge. It uses standard browser keyboard events that are widely supported. For best results, use the latest version of your browser.
Is my keyboard data private?
Yes, all testing happens entirely in your browser. No keystroke data is recorded, stored, or transmitted to any server. Your privacy is protected—everything runs locally on your device.
