Keyboard Tester

Choose your keyboard, start the test, and press each physical key. Green keys have sent a key event successfully.

Ready. Click Start test, then use your keyboard.

Last key: —

Press Escape to record Esc and pause the test, or click outside the keyboard. Fn, Eject, media keys, and some system shortcuts may not reach the browser; an unlit key does not necessarily mean it is broken. Function keys may require Fn. This test runs locally and does not store or send your keystrokes.
