Click, right-click, and scroll inside the test area above — counters update live.
How it works
- Click each mouse button inside the test area.
- Scroll up, down, and sideways if your mouse supports it.
- Watch the counters update live for each input.
Testing listens for the browser's mouse and wheel events —
mousedown, contextmenu, and
wheel — and tallies each one, making it easy to spot a
button that doesn't register or a wheel that jumps unexpectedly.
FAQ
Is my activity uploaded anywhere?
No. Detection happens entirely in your browser — nothing is sent to a server.
What mouse events does it detect?
Left, right, and middle clicks, back/forward side buttons, and scroll wheel movement, both vertical and horizontal.
Why would I need this?
To check for a stuck or double-clicking button, a worn scroll wheel, or to confirm every button on a new mouse actually registers.
Does it work with a trackpad?
Yes — click and scroll gestures on a trackpad are detected the same way as a physical mouse.
