Gamepad Button Test

Test controller buttons and D-pad presses with the browser Gamepad API.

Gamepad Button Test helps controller users testing USB, Bluetooth, console-style, and browser-compatible gamepads. It focuses on button mapping, stick drift, trigger range, polling and vibration support and runs directly in the browser.

How to use Gamepad Button Test

Open Gamepad Button Test on the same browser and device you want to diagnose.
Gamepad pages use the browser Gamepad API; connect the controller and press a button to expose it.
Run the visible gamepad test controls and watch the live result area update before judging the hardware.
Repeat the test once or twice, then compare related InputLab tools if the gamepad behavior looks inconsistent.

How to read the result

Gamepad Button Test is most useful when you read the result as a practical browser diagnostic. Browser support, Bluetooth latency, driver mapping, and controller firmware can affect readings. A repeated pattern across multiple runs is more meaningful than one isolated spike, missed event, or visual artifact.

Privacy and permissions

Gamepad pages use the browser Gamepad API; connect the controller and press a button to expose it. Tests are designed to run locally in the browser, with permissions controlled by the browser.
