How to test your controller
- Connect your controller by USB or Bluetooth.
- Press any button — the browser then shows it here.
- Press every button and pull both triggers: each one lights up on the diagram, and triggers show 0–100%.
- Move both sticks in full circles: the trail should reach the outer ring evenly.
- Let go and run the drift test, then try vibration.
What is stick drift?
Stick drift is when an analog stick reports movement while you're not touching it — your character walks or the camera turns on its own. It's common on worn PS5 DualSense, Xbox and Switch Joy-Con sticks. The drift test measures how far each stick sits from centre at rest:
- Under 5% — normal; games ignore this with a deadzone.
- 5–12% — slight drift; usually fine, but raise the in-game deadzone if you notice creep.
- Over 12% — real drift; cleaning, recalibrating or replacing the stick module usually fixes it.
Frequently asked questions
Why doesn't my controller show up?
Browsers hide gamepads until you press a button on one, so a website can't fingerprint you by the devices you own. Press any button. If it still doesn't appear, reconnect it, or try Chrome or Edge.
Does it work with PS5 DualSense and Xbox controllers?
Yes — any controller your browser recognises works. Most PS4, PS5, Xbox and Switch Pro controllers use the standard layout shown in the diagram; for others, use "Show raw values" to see every button and axis.
Why can't I test vibration?
Vibration needs browser support (Chrome and Edge have it; Firefox and Safari mostly don't) and a controller that exposes its motors.
Is anything sent to a server?
No. The tester reads your controller with the browser's Gamepad API and everything stays on your device.
