DualShock Calibration GUI uses WebHID to show controller details and adjust supported stick calibration on a desktop browser; it can permanently write device settings.
Controller diagnostics and calibration
The page exposes controller information, quick tests, stick-center and range calibration, and fine-tuning controls. It asks the visitor to connect a supported DualShock, DualSense, DualSense Edge, or VR2 controller through a compatible desktop browser.
Browser and device requirements
The source page says WebHID support is required and does not support phones or tablets. Firefox needs a WebHID extension; Chrome or Edge on desktop is suggested by the page.
Read the warning before saving
Calibration changes can affect controller behavior. The site warns that calibration cannot repair worn joystick hardware and may make drift worse if used without replacing damaged parts. Save changes permanently only after understanding how to restore or undo them.
How to use this page
1. Open the page in a supported desktop browser and connect a listed controller. 2. Run a quick test before changing calibration values. 3. Review the site warning and recovery controls before saving changes to the device. Frequently asked questions Can I use it on a phone? The page says mobile devices are unsupported. Will calibration fix stick drift? The site says calibration cannot repair worn mechanical parts and may worsen symptoms in some cases.
