What is Keyboard Tester Pro?
Keyboard Tester Pro is a free online tool that lets you check every key on your keyboard. Simply press any key and watch it light up in real time on a virtual keyboard. You can switch between Windows, Mac, and international layouts to match your device, and even track all your keystrokes during the session. The tester runs entirely in your browser, so there's no download or installation needed, and it doesn't collect or store any data. It’s perfect for troubleshooting faulty keys, testing new keyboards, or confirming repairs.
