About This Tool

KeyLab is a precision keyboard tester built for enthusiasts and professionals alike. It supports 60%, 65%, 75%, TKL, 98%, and 100% full-size layouts, letting you instantly verify every key across the most popular form factors. Whether you're building a custom board or diagnosing a factory unit, KeyLab provides accurate, real-time feedback on every keystroke.

With built-in N-Key Rollover (NKRO) detection, you can confirm that your keyboard registers every simultaneous press without ghosting or dropped inputs—critical for gaming and high-speed typing. The live counter shows exactly how many keys are held down at once, so you can validate anti-ghosting performance in seconds.

Suspect a faulty switch? KeyLab's 50ms chattering detection flags any key that double-fires within an abnormal window, highlighting it in red and raising a dashboard alert. Combined with per-key tested markers and a progress bar, this tool turns switch diagnostics into a fast, visual workflow—no external software required.
