Mouse Tester - Diagnose a faulty mouse: double-click, CPS & scroll test

Your mouse is acting up — double-clicks, a jumping scroll wheel — but is it the hardware, the driver, or the game? Mouse Tester answers in 30 seconds, right in your browser. Test every button with live feedback, catch worn microswitches with an adjustable double-click threshold, measure CPS, check scroll precision, inspect sensor smoothness via trails, and review a full event log. No downloads, no sign-up. 100% private — data stays in your browser, works offline. Free forever.
