Test Mechanical Switches & Laptop Keyboards Online
Whether you built a custom mechanical keyboard with magnetic Rapid Trigger switches (like Wooting 60HE) or are verifying a laptop keyboard before buying, testing every key PCB trace is critical. Our online keyboard checker captures raw browser keyboard events (`keydown` and `keyup`), providing visual confirmation when switches register properly.
N-Key Rollover (NKRO) & Anti-Ghosting
In rhythm games and FPS titles (like strafing W+A+Shift+Space in Valorant), pressing multiple keys simultaneously must register cleanly without dropped inputs. Modern mechanical keyboards feature 100% NKRO, while cheaper membrane keyboards cap out at 3KRO or 6KRO due to shared matrix wiring.
Troubleshooting Mechanical Key Chatter
Mechanical key chatter occurs when a dirty or damaged switch leaf contacts multiple times on a single keypress. Our tool highlights tested keys green so you can press keys repeatedly to verify reliability.
