About this controller test
Controller Test is a bench for game pads that lives in a browser tab. It listens to your controller through the Gamepad API, or, experimentally, over WebHID in desktop Chrome and Edge, and turns raw numbers into a call you can act on: fine, early wear or faulty, with the next step.
Built for
Players chasing a drifting stick before a warranty claim, people buying a used pad who want proof it works, and anyone who wonders whether that missed input was the controller or the game. Model pages know the quirks of each pad: the squarer stick gate of an Xbox controller, trigger rumble, the DualSense’s adaptive triggers.
Under the hood
Every reading is processed on your own machine; there is nothing to sign up for and nothing to upload. Once loaded, the bench keeps working without a connection.
When a number can’t be measured honestly from a browser, input lag in milliseconds for one, the bench leaves it out rather than guessing. How the bench works walks through both ways it reads a pad.
