Gamepad Tester Guide

See every axis and button of a connected controller, with the pressed buttons lit up.

Gamepad Tester reads the browser’s Gamepad API and displays controllers it reports, including stick axes (typically -1 to 1) and button values (typically 0 to 1). It cannot determine whether a controller is physically broken or test vibration.

Check a controller

Connect a gamepad, open the page, then press one of its buttons. Connected should show a controller count and a panel with its name, axes, and buttons. Press a face button: its value should rise while pressed, and Last input names that button if the browser provides the standard mapping. Move a stick: watch the relevant axis change from around 0 and return toward it when released. With no accessible controller, the page prompts you to press a button or reports that the API is unavailable.

Browsers often reveal a gamepad only after interaction. The exact names and readings depend on the device and browser; small nonzero values at rest are not a diagnosis by themselves. No controller readings are uploaded by this tool.

Where your input goes

Processing runs in your browser. The tool does not upload your input to ilham.dev.

Questions you might have

Why is the controller missing until I press a button?
Browsers hide gamepads until an input event proves one is being used, which is a privacy measure. Press any button on the pad and it will appear, then stay listed until it is disconnected.
A stick reports a small value while untouched. Is it broken?
This page reports values rounded to two decimals; it does not apply a configurable dead zone or diagnose hardware. Compare repeated readings at rest and while moving the stick, then check your game or OS calibration before deciding something is faulty.
Can it test vibration or the light bar?
Not here. Those need the haptics actuators a browser exposes separately, and support varies by pad and by browser, so this page sticks to the axes and buttons that every controller reports.
