About the Online Mouse Tester
Our free online mouse test lets you verify that every button on your mouse is working correctly. Using the browser MouseEvent API, this tool detects left clicks, right clicks, middle button presses, and side buttons in real time.
Whether you are troubleshooting a malfunctioning mouse, testing a new gaming mouse, or checking for double-click issues, this tool provides detailed event data including button codes, click coordinates, and movement speed.
The DPI test section helps you measure your mouse sensitivity by tracking movement distance against pixel displacement. The scroll test monitors your scroll wheel for smooth operation and correct direction detection.
