A mouse test checks whether your buttons, scroll wheel, double clicks, and pointer movement reach the browser correctly. Use this live diagnostic to troubleshoot a mouse without installing software or uploading input data.
Move or click inside the test area
Click and scroll anywhere in this panel. Right-click is contained here; side-button navigation may still be reserved by your browser or operating system.
Place your pointer over the large diagnostic panel and move it around to confirm tracking.
Try left, middle, right, back, and forward buttons. Each detected button gets a count and tested state.
Scroll in both directions and double-click inside the panel to verify those signals separately.
Use the recent event log to compare inputs, then reset the full diagnostic before another test.
Move, click, double-click, and scroll inside the test area. The page reads standard browser mouse events and updates each diagnostic immediately.
You can test left, middle, right, back, and forward buttons when your browser exposes them. Some browsers or operating systems reserve side-button shortcuts.
Place the pointer over the test area and scroll vertically or horizontally. The wheel panel shows direction, event count, and accumulated delta values.
No. Mouse events are processed only in your browser and disappear when you reset or leave the page. Nothing is uploaded or stored by this tool.
Try the button inside the test area, check mouse software mappings, and test another browser. Hardware, driver, browser, or operating-system shortcuts can intercept an input before a website receives it.
