Test every button, stick and trigger on PlayStation, Xbox, Switch and PC controllers, and check for stick drift.
Controller testers

PS5 Controller Tester

Sticks, triggers and vibration
Stick Drift Test
Measure stick drift at rest, see which way it creeps and get the deadzone that hides it.
Controller Vibration Test
Run each rumble motor on its own, including Xbox trigger motors, to find a dead or weak one.
Controller Latency Test
Measure your controller's update rate and button response, and compare cable with wireless.
Test any controller
The gamepad tester works with any controller your browser can see: buttons light up, triggers show how far they move and each stick draws its position, on a drawing that matches your controller. Start with the controller tester when a controller works in one place but not another on PC: it shows what your computer receives and walks through driver, Steam and game fixes. There are dedicated pages for the ps5 controller tester, the ps4 controller tester, the xbox controller tester, the switch pro controller tester and the joycon tester.
Drift, rumble and timing
Stick drift is the fault most people are looking for. The stick drift test measures how far each stick wanders at rest and how round its outer circle is. The controller vibration test runs each rumble motor, and the controller latency test checks how often the controller reports.
Joysticks and wheels
Flight sticks, HOTAS setups, racing wheels and pedals have their own pages: the joystick tester and the steering wheel test.
Fixing drift
The how to fix stick drift guide covers cleaning, deadzones, calibration and repair, with platform guides for ps5 controller drift, xbox controller drift and joycon drift.
