Toolkit
Keyboard testing tools.
A complete set of free, browser-based tools to test, diagnose, and benchmark any keyboard — no drivers, no downloads, and nothing you press ever leaves your device.
Test your keyboard
Keyboard TesterPress every key and watch it light up — the fastest way to find a dead, stuck, or unresponsive key.
Anti-Ghosting / NKRO TestHold several keys at once to see how many register together and whether your board does N-Key Rollover.
Event LoggerInspect the raw key, code, keyCode, location, and modifier flags for every event — and catch key chatter.
Shortcut TesterCheck that key combinations like Ctrl+Shift and Alt+Tab register the way you expect.
Polling Rate TestEstimate your keyboard’s report rate in Hz from the timing of your keystrokes.
