Browser-side diagnostic only. Connect the controller in your operating system first; this page cannot pair Bluetooth or install drivers. Results depend on the browser, operating system, connection and controller mapping.

INPUTS TO CHECK

What the tester should show

Face buttons
D-pad
L1/R1
L2/R2
Two sticks
Back buttons

Press each control on the full gamepad tester. The button matrix and raw API panel are more reliable than a brand label when a controller is in a different mode.

OUTPUTS AND LIMITS

What may not appear

Rumble depends on the selected mode and connection

Rumble is an optional browser capability. A missing rumble button does not by itself prove that the motor is damaged.

KNOWN QUIRKS

Before calling it broken

Changing modes can make the same physical controller appear as a different device.
Back buttons may not appear in the standard Gamepad API mapping.
