Frequently Asked Questions
My controller isn't showing up?
Most browsers require you to press a button on the controller before it becomes visible to the website. Try pressing A/X or moving a stick. Also ensure your drivers are installed if on Windows 7.
Does vibration test work on all devices?
Vibration support depends on your browser and OS. Chrome on Windows usually supports Rumble. Firefox and macOS often have limited or no support for haptic feedback in the browser.
How do I fix stick drift?
This tool helps diagnose drift. If the visual stick isn't centered when you aren't touching it, you have drift. You can try cleaning the sensor with compressed air or adjusting deadzones in your game settings.
Is this tool free?
Yes, GamepadTester.dev is completely free and open for everyone to use.
