Frequently Asked Questions

Why isn't my controller detected by this controller tester?

Browsers usually require a button press before they'll detect a connected controller due to how the Gamepad API works. Press any button, check your cable or Bluetooth connection, and make sure you're using a browser that supports gamepads, such as Chrome, Edge, or Firefox.

Does this controller tester work with wireless controllers?

Yes. Once a wireless controller is paired with your computer or phone at the operating system level, this tool can read its input the same way it reads a wired controller.

Is this controller tester free to use?

Yes, this tool is completely free, requires no signup, and runs entirely in your browser without any download.

Can this controller tester detect stick drift or dead zones?

Yes. Watch the stick position indicator while the stick is centered and untouched. If it doesn't rest at 0.00, 0.00, that can indicate drift or a dead zone issue with your controller.
