Device Tester
Test a keyboard, mouse, or gamepad in your browser. The keyboard tester autodetects layout (ANSI 104, TKL, 60 %, ISO 105, Dansk ISO, or Mac) and lets you override it. Mouse tester reports buttons, wheel, position, click-rate and an interactive drag pad. Gamepad tester polls every connected controller in real time.
Test every key on a visual layout. Auto-detected layout with ANSI 104 / TKL / 60% / ISO 105 / Mac overrides, NKRO check, repeat detection, and a colour-coded ‘visited’ map.
Layout
US/EN full-size with numpad. The wide L-shaped Enter is ISO; ANSI Enter is a single 2.25u key.
