About Us

Welcome to Mouse Tester — your free, no-download tool to check mouse buttons, scroll, DPI, and performance.

We built this platform for one reason: to help users test their mice fast and accurately — without installing anything or risking privacy. Whether you’re a gamer fine-tuning aim, a designer chasing pixel-perfect control, or an office pro fixing lag, our goal is to make your workflow smooth and precise.

Our tester runs 100% in your browser, powered by lightweight scripts that capture real-time input. We don’t store or share your data. Everything happens on your screen — private, instant, and secure.

At Mouse Tester, we believe better performance starts with better testing. Thousands of users trust our tool daily to detect double clicks, scroll issues, sensor drifts, and DPI mismatches before they cause real problems.

So go ahead — click, scroll, and test. Keep your device sharp, your gameplay smooth, and your performance high.

Your mouse, your edge — tested by Mouse Tester.
