Keyboard diagnostics

Keyboard Tests

Three keyboard diagnostics that run straight from your browser. Keyboard CPS measures keystrokes per second across five durations, the NKRO test counts how many keys register at once, and the chatter test flags switches that double fire. Every tool scores you instantly and keeps a personal best.
