Deadzone Test
Turn drift readings into a practical in-game deadzone.
Stick Drift Test Online
Keep your hands off the analog sticks and run an 8-second rest sample. The drift test reports left/right center offset, drift severity, and a recommended game deadzone.

How The Drift Sample Works
The tool measures analog stick distance from the center while the controller is idle. A small offset is normal. A large or unstable offset means the game may receive movement even when you are not touching the stick.
ControllerTest does not repair drift. It gives a repeatable browser-based reading and a deadzone suggestion that can help you decide whether to adjust settings, clean the stick, or replace the module.
Next Controller Checks
After the rest sample, test circularity and input values to separate center drift from worn stick gates or broken buttons.
Circularity Test
Check whether the stick reaches the full gate evenly.
Controller Input Test
Watch button, axis and trigger values live.
