Mouse test FAQ
What mouse buttons can this online test detect?
It detects left click, middle/scroll wheel click, right click, back side button, forward side button, and any additional buttons. This covers standard mice, gaming mice with extra programmable buttons, and trackpads.
Is this mouse test free and does it require installation?
Completely free with zero installation. The test runs entirely in your browser using standard web technologies. No downloads, no plugins, no account needed.
Does the mouse movement test work on all operating systems?
Yes. The cursor tracking and trail visualization work on Windows, macOS, Linux, and ChromeOS. As long as you have a modern browser (Chrome 55+, Firefox 53+, Safari 12.1+, Edge 79+), the test will function correctly.
Can I test a wireless mouse or Bluetooth mouse with this tool?
Absolutely. The tool works at the browser event level, so it does not matter how the mouse is connected — USB, wireless receiver, or Bluetooth. It also works with built-in laptop trackpads.
Why does the movement trail show different speeds at different times?
The speed indicator is calculated in real time based on how far and how fast the cursor moves between frames. Faster physical mouse movement produces higher values. The trail visualization also uses progressive opacity and line width — newer segments appear brighter and thicker to show the most recent path.
