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

Button matrix
D-pad
Sticks when present
Triggers when exposed

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

Usually no rumble guarantee

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

Some devices only appear after pressing a button.
A controller can be visible to Windows but hidden from the browser if another application has taken exclusive control.
