Keyboard Event Tester

It shows the key, code, keyCode, which, modifier keys (Ctrl/Alt/Shift/Meta), and repeat values from the browser's KeyboardEvent the moment you press a key.

key represents the actual character produced, which can depend on keyboard layout or language settings, while code represents the physical key position and stays the same regardless of layout.

keyCode and which are legacy APIs that modern web standards recommend replacing with key and code. This tool still shows them since they're useful for debugging older code.

No. All keyboard event handling happens entirely in your browser and is never sent to or stored on a server.

You can test any standard keyboard input the browser recognizes. Gamepad input requires a separate Gamepad API and isn't supported by this tool.
