Keyboard Tester Pro is a professional hardware diagnostic tool designed to verify keyboard and mouse functionality in real time. The application visually highlights every key press on a full keyboard layout, allowing you to instantly detect non-working keys, double-typing (chatter), ghosting, rollover limits, and latency issues. It is useful for gamers, developers, technicians, and anyone troubleshooting a faulty keyboard. The tool also tracks hold duration, scan codes, modifier states, and mouse input while maintaining a clean, distraction-free interface. Reports and screenshots can be exported for documentation or warranty claims. All testing runs locally on your computer and requires no internet connection. Keyboard Tester Pro helps you quickly confirm whether a problem comes from hardware failure, dust buildup, worn switches, or software conflicts.
