Question 1

How do I connect my controller to the gamepad tester?

Accepted Answer

Connect your controller via USB or Bluetooth, then press any button. The browser will automatically detect it using the Gamepad API. Works with Xbox, PlayStation, Nintendo Switch Pro, and most generic controllers.

Question 2

Why is my gamepad not detected?

Accepted Answer

Make sure your controller is properly connected and try pressing a button. Some browsers require user interaction before detecting gamepads. Try Chrome or Edge for best compatibility. If using Bluetooth, ensure the controller is paired in your OS settings.

Question 3

Can I test controller stick drift?

Accepted Answer

Yes! The analog stick visualizer shows real-time axis values with 3-decimal precision. If your stick shows non-zero values when centered (typically > 0.05), it indicates drift. Compare left and right sticks to identify which one needs calibration or replacement.

Question 4

Does the gamepad tester work with PS5 DualSense controllers?

Accepted Answer

Yes, PS5 DualSense controllers are fully supported via USB and Bluetooth. All buttons, analog sticks, triggers, and the touchpad are detected. Haptic feedback testing depends on browser support.

Question 5

How do I test controller vibration?

Accepted Answer

The vibration test requires browser support for the Gamepad Haptic Actuator API. Chrome and Edge support vibration for most Xbox and PlayStation controllers. Connect your controller and use the vibration test section.

Question 6

Can I test multiple controllers at the same time?

Accepted Answer

The Gamepad API supports up to 4 simultaneous controllers. Currently HWProbe displays the first connected controller. Multi-controller support is coming soon.

Question 7

What is analog stick deadzone?

Accepted Answer

Deadzone is the area around the center of an analog stick where small movements are ignored. A small deadzone (< 0.05) means more precision but may show drift. Our tester displays exact axis values so you can determine your controller's effective deadzone.

Question 8

Is this gamepad tester free?

Accepted Answer

Yes, completely free with no ads, no downloads, and no data collection. Everything runs 100% in your browser. The tool is open source on GitHub.
