Online mouse test
Five tests that run straight in your browser, with nothing to install and no data leaving your machine. Pick what you need to diagnose: clicks that never register, double clicks that fire on their own, click speed, scroll wheel behaviour or sensor polling rate.
Pick a test
Mouse click test
Check whether every mouse button registers clicks correctly. See the interval between clicks and spot buttons that drop or repeat input.
Click test →Unintended double click test
Find out whether your mouse is double clicking on its own. The test measures the gap between clicks and flags repeats below the human threshold.
Double click →CPS test (clicks per second)
Measure how many clicks per second you can reach. Pick a duration, watch the live average and compare against your previous attempts.
CPS →Mouse scroll test
Test your mouse wheel and detect scrolling that skips, reverses on its own or stalls. See direction, step count and irregular events.
Scroll →Polling rate test
Measure your mouse polling rate in Hz. Find out whether it really delivers the promised 1000Hz and compare against the configured value.
Polling rate →Before you start
Every test needs a physical mouse — trackpads and touchscreens emit different events, so their results are not usable for diagnosis. On a wireless mouse, test with the battery charged: a weak battery drops clicks in a way that looks exactly like a failing switch.
