Frequently Asked Questions
How do I test my mechanical keyboard?
Simply navigate to our Keyboard Tester, make sure the browser page is focused, and press keys. Key switches illuminate instantly, and stay green on release to confirm double-stroke accuracy.
What is a good CPS score on the Click Checker?
A typical office user clicks between 5 to 7 Clicks Per Second (CPS). Competitive video gamers using dynamic butterfly triggers routinely register 12 to 15+ CPS. Calibrate yours on our Mouse & CPS page.
Is this keyboard tester safe to use?
Yes, 100%. InputTest.online operates completely client-side. We utilize zero logins, cookies telemetry or database servers, assuring your private character sequences and patterns are completely secure.
