Connect a DualShock 4 through WebHID to check every button, stick, trigger, touchpad contact, motion sensor, battery reading, lightbar and rumble motor. Device data is processed locally in your browser.
The test displays digital buttons, analog sticks and triggers, up to two simultaneous touchpad contacts, raw gyroscope and accelerometer readings, battery level, charging state, connection type and HID report rate.
WebHID requires a compatible Chromium-based desktop browser and a secure page. The WebHID-DS4 library primarily targets official DualShock 4 models; third-party compatibility is not guaranteed. The library may not detect a disconnection, and lightbar or rumble commands may not work over Bluetooth. Reconnect the controller or use a USB data cable if values stop updating.
