What is the Gamepad & Controller Tester?
Plug in or pair a controller, press any button and this tester shows it instantly: every button lights up with its name, triggers show how far they are pressed, and both analogue sticks are drawn live with their exact axis values. It works with Xbox, PlayStation DualShock and DualSense, Nintendo Switch Pro and most generic USB or Bluetooth pads.
Use it to check a new or second-hand controller, find a button that does not register, test vibration, and detect stick drift — the common fault where a stick reports movement while you are not touching it. The drift check watches the sticks for two seconds and tells you how far they wander from centre. Everything runs in your browser using the Gamepad API; nothing is sent anywhere.

Questions people ask
Why does the tester not see my controller?
Browsers hide gamepads until you press a button. Press any button, then it appears. Also make sure no other app has exclusive control.
What is stick drift?
The stick reports movement at rest, so a character or camera creeps on its own. It is caused by dust, wear or a failing potentiometer.
How much drift is normal?
Values within about ±0.05 of zero are normal. Larger resting values usually mean drift.
Does it support PlayStation and Xbox controllers?
Yes — Xbox, DualShock 4, DualSense, Switch Pro and most generic pads using the standard mapping.
Can I test vibration?
Yes, in browsers that support it (Chrome and Edge). The button sends a short dual-motor rumble.
