Frequently asked questions
What is a gamepad tester?
A gamepad tester is a browser tool that displays controller buttons, triggers, D-pad directions, and analog stick positions as you use them.
Why is my controller not detected?
Connect the controller by USB or Bluetooth, focus the page, and press a button. Some browsers hide controller data until the user interacts with the device.
How do I check for analog stick drift?
Release the stick and watch its marker and values. If they stay away from zero, raise the dead-zone setting until the centered input becomes zero.
Can this tester check controller vibration?
It can send a short rumble when both the browser and controller report vibration support. Not every browser exposes that feature.
Does GameShelf upload controller data?
No. The test reads the browser Gamepad API locally and does not require an account or upload controller inputs.
