All tests run locally in your browser with standard Web APIs — your input never leaves the machine. Keyboard and mouse use the raw keyboard/mouse event pipeline; audio uses the Web Audio API; gamepad polls the Gamepad API.
Chrome / Edge 120+, Firefox 121+, Safari 17+. Full gamepad support needs USB or Bluetooth HID. Microphone tests require a mic permission prompt. Some features may be limited on mobile browsers.
