About this test
The gamepad tester uses the browser's Gamepad API to show every button, analog trigger value and stick axis in real time. It measures how far each stick sits from centre when you are not touching it, which is the clearest sign of stick drift, and can trigger vibration on supported controllers.
How to use this test
- Connect the controller by USB or Bluetooth and press any button.
- Press every button and pull both triggers fully.
- Let go of the sticks and read the drift value at rest.
Frequently asked questions
Which controllers work?
Xbox, PlayStation DualShock and DualSense, Switch Pro and most USB or Bluetooth gamepads. Chrome and Edge support the most models.
How much drift is too much?
Readings under 0.05 at rest are normal. Above 0.10 usually causes in-game drift and needs a larger dead zone or repair.
