How the mouse tester works
Move and click inside the pad. We show coordinates, button state and scroll delta from browser pointer events.
Useful for double-click issues, dead middle button and scroll wheel glitches.
How to use
Open: Load the tester.
Move: Watch x/y.
Click: Try all buttons.
Scroll: Use the wheel.
Mouse buttons acting weird?
Gaming mice fail mid-match; office mice double-click alone.
Click each button and scroll here to isolate hardware vs software.
Practical tips
- Use HTTPS and allow permissions only when needed.
- Close other tabs that hold the device exclusive.
- Try another browser if the API is blocked.
- Share the link with support if a key or button fails.
- Right-click is captured (context menu blocked in the pad).
- Try another USB port if nothing registers.

When to upgrade gear or apps
If hardware or workflow keeps failing, a better peripheral or writing app saves time.
