Frequently Asked Questions
Common questions about our mouse test tool.
What is our mouse test tool?
Our mouse test tool is a free online tool that checks every input on your mouse — left, right, and middle clicks, the back and forward side buttons, and the scroll wheel up and down. It also shows your real-time clicks per second and the interval between clicks. Everything runs in your browser on Windows, Mac, or Linux, with no install, no sign-up, and no data leaving your device.
How do I test my mouse?
Start the mouse test by clicking each button and rolling the scroll wheel up and down. The matching part lights up on the mouse when it works.
What mouse buttons can I test?
Left, right, and middle click, the back and forward side buttons, and the scroll wheel up and down.
Why don't my side buttons light up?
Some browsers block the back and forward buttons. Try Chrome or Firefox. If they still fail, the buttons may be broken.
What does a failed test mean?
A button or the scroll wheel did not work. First try a different browser — some block the side buttons. If it still does not light up, your mouse is likely worn or broken, and it may be time for a new one — see the ones we recommend below.
Does it test DPI or polling rate?
Not yet. This mouse test currently checks your buttons, scroll wheel, and click speed. We may add DPI and polling rate later.
Is it free? Do I need to install anything?
Yes, the mouse test is completely free. No download, no sign-up, no plugin — it runs right in your browser.
Are my clicks private?
The mouse test runs entirely in your browser. Your clicks are never uploaded or sent to a server.
