Gamepad Tester - Test Controller Buttons, Sticks, Triggers and Drift Online
Gamepad Tester
See every button and stick on your controller, live
Every Input
Shows each button with its pressure value, each trigger as an analog bar and each stick as a moving dot with its raw numbers.
Stick Drift Check
Leave the sticks alone and the tool records how far they wander from the centre, then suggests a dead zone that would hide it.
Vibration Test
Press a button to run the rumble motors in browsers and controllers that support it.
Private
Controller input is read in your browser and never sent anywhere.
How to Test a Controller
Connect the controller by USB or Bluetooth, then press any button. Browsers hide gamepads until you use them, so a controller that is plugged in can look missing until the first press. When it appears, press each button and trigger in turn and check that the matching box lights up, and that analog triggers fill gradually rather than jumping from nothing to full.
Stick drift means a stick reports movement when you are not touching it. A small offset is normal, which is why games use a dead zone. To measure it, put the controller on a flat surface, do not touch it for a few seconds, and read the largest resting offset; roughly 0.05 or more suggests wear. Layout names follow the standard mapping used by Xbox and PlayStation controllers; other devices show numbered buttons and axes.
Key Takeaways
- Press a button first: Browsers only report a gamepad after it has been used on the page.
- Standard mapping: Controllers that follow the standard layout get named buttons. Others use button numbers.
