Test every part of your mouse in the browser. These tools check left, right, middle and side buttons, catch double-click chatter, measure scroll behaviour, estimate polling rate and DPI, and spot drift, jitter or skipped frames. Nothing is installed and nothing is uploaded — events stay on your device.
Pick a focused test below if you already know the symptom, or start with the main Mouse Tester for a full pass. Results help you decide whether to clean the sensor, replace switches, change USB ports, or update firmware before you buy a new mouse.
