About Mouse Tester
A free, browser-based tool to test your mouse buttons, scroll wheel, and input accuracy—no signup, no install.
Our Mission
Mouse Tester helps users quickly check if their mouse is working correctly. Clicks, scroll wheel, and side buttons are tested right in your browser. Everything runs locally—we don't collect or store your click data.
Whether you're troubleshooting double-clicks, scroll jumps, or unresponsive buttons, our tool gives you instant feedback. We aim to keep it simple, fast, and private.

Check Scroll & Buttons
