What this gamepad checker tests
Press every control on your pad and watch it light up. Anything that stays dark is a button your computer never received — that is a hardware fault, not a game setting.
- Stick drift and dead zones — measures resting offset and jitter, and grades it
- Buttons and D-pad — face buttons, bumpers, stick clicks, Start/Select/Guide
- Analog triggers — full 0–100% travel, so you can spot a trigger that no longer bottoms out
- Vibration — both rumble motors, tested separately
- Polling rate — how many updates per second your pad actually delivers
How to tell if your controller has stick drift
Real drift means the stick reports movement while you are not touching it. Put the pad down on a flat surface, hands off, and run the 5-second test. A healthy stick rests somewhere under 0.05. Between 0.05 and 0.10 it is off-centre but harmless, because games ignore that range. At 0.10 and above your character will start walking or your aim will pull on its own.
Which controllers work
Anything your browser recognises as a gamepad: PlayStation 5 DualSense, PlayStation 4 DualShock 4, Xbox Series and Xbox One controllers, Nintendo Switch Pro, 8BitDo pads, and generic USB or Bluetooth joysticks. Nothing is installed and no data leaves your device — the test runs entirely in your browser.
