Gamepad Tester Guide
See every axis and button of a connected controller, with the pressed buttons lit up.
A short companion for Gamepad Tester: when it is useful, what it expects, and what to check before using the result.
What it does
Inspect a connected controller: every axis with its travel, every button with its pressure, and a running note of the last input seen. It is the quick answer to whether a pad works, which stick drifts and which button has stopped registering.
Use the tool
Open Gamepad Tester, add the input the tool asks for, run it, and check the output before using it elsewhere.

Questions
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?
A little drift below about 0.05 is normal on worn analogue sticks and browsable games compensate with a dead zone. A value that keeps climbing on its own, or a stick that never reaches 1 at full travel, points to a real fault.
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.
