Test every mouse button, click interval, scroll wheel and observed movement frequency in your browser.
Private by designTest buttons, double-click chatter, click speed, wheels and polling rate online.
Move, click and scroll anywhere on this page to see each event.
Click, scroll or move to start logging events.
Start with the symptom you can reproduce, then repeat the same test before changing hardware, a USB port or a wireless connection.
Press each physical button and watch the browser event arrive in real time. The live map helps you spot a missing side button, a remapped input or a click that only works intermittently before you replace the mouse.
Run the mouse button test
A healthy deliberate click should leave a comfortable gap. Repeat the same button several times and use the interval log to separate an intentional double click from possible switch chatter under 50 milliseconds.
Check for double-click chatter
Scroll up and down to catch skipped ticks, reversed direction and a wheel that feels sticky. When sensitivity also feels wrong, measure a known distance with the DPI tool and compare repeated runs under the same pointer settings.
Test the scroll wheel
Move in wide, fast circles and compare the movement events your browser receives. The reading is an on-page estimate, so use it to compare wired, 2.4 GHz and Bluetooth setups rather than treating one peak as sensor firmware proof.
Measure observed polling rate
Each tool focuses on one signal, with long-tail guidance for diagnosing a gaming mouse, office mouse or replacement switch.
Check left, right, middle and side buttons with a live event log.
↗Spot mouse chatter with interval thresholds under 50 milliseconds.
↗Measure debounce gaps when a single press turns into repeated clicks.
↗Measure CPS while you click as fast as your switch can respond.
↗Count wheel ticks and catch skipped, reversed or sticky scrolling.
↗Check horizontal tilt, vertical scroll and middle-click events.
↗Compare the physical button you press with the browser event received.
↗Estimate mouse event frequency while you move across the page.
↗Measure cursor distance and compare your configured mouse DPI.
↗Check if a mouse button drops while you drag and hold.
↗A clean click counter for switch endurance and repeated input.
↗Run 1, 5, 10, 30 or custom second clicks-per-second trials.
↗Convert a timed click run into a repeatable CPM result.
↗Compare 50, 80, 150 and 350 ms double-click thresholds.
↗Find rapid wheel direction reversals and encoder irregularities.
↗Inspect pointer direction changes during smooth movement.
↗Trace a live sensor path to spot skips and movement instability.
↗Track hits, misses and aim accuracy in a 20-second drill.
↗Check keys locally when a mouse issue may be a wider input problem.
↗Measure browser click-to-paint response with rolling samples.
↗Review and export your last thirty local CPS results.
↗Use a repeatable process before buying, returning or repairing hardware.
Live button counts, click intervals, scroll direction, movement rate and the most recent action appear as you test.
The double-click page flags suspiciously short intervals and gives you a simple reference table for repeat tests.
There is no login or upload. Standard pointer events are measured in your current browser session.
Mouse Click Test listens to normal browser mouse events. It counts buttons, wheel ticks, intervals and movement locally, so you can troubleshoot a mouse without installing software.
Yes. The double-click tester records the interval between clicks and highlights unusually short intervals. Repeat the check at a normal pace before deciding a switch is faulty.
Yes. The tools run in your browser with no account, upload or required tracking. Visible test state resets with the tool, while optional CPS history stays in local storage until you export or clear it.
Run the mouse button, double-click, scroll wheel and hold-drag tests, then repeat in another browser and USB port. Record the event log and the conditions.
