Calibrate your controller in the browser: recentre the sticks, measure stick drift, set deadzones and adjust trigger sensitivity. Connect your gamepad and press any button.
Top: raw · Bottom: with sensitivity curve
Click “Calibrate centre” and let go of the sticks — the tool finds the exact rest position and shows the deviation (drift) as a percentage. That tells you whether the camera or character moves on its own, and compensates for the offset in software.
With “Measure range” you sweep both sticks fully once so the tool records the maximum travel needed for full in-game speed. The deadzone slider hides tiny, unwanted movements around the centre.
The analog triggers L2/R2 (LT/RT) are shown with their raw and adjusted values. The sensitivity curve lets you set how finely, for example, accelerating in racing games responds.
The browser reads the controller via the Gamepad API and computes the calibration in software; your settings are stored locally. Writing directly to controller firmware is not possible in the browser, but you can apply the deadzone and curve values in Steam Input or your games.
It computes a software calibration (centre, deadzone, curve) and stores it locally. The browser cannot write to controller firmware, but you can apply the values in Steam Input, for example.
An area around the centre where the stick is ignored. A small deadzone suppresses drift and unwanted micro-movements.
