Gamepad Tester

Connect your controller and press any button to start. Works with PS5, Xbox, Switch, and generic USB/Bluetooth gamepads.

Supported when your browser exposes the controller through the Gamepad API.

Xbox One / Series X|S DualShock 4 / DualSense Switch Pro Controller 8BitDo and HID gamepads

Buttons, sticks, triggers, and raw axes are the core compatibility target. Rumble, trigger motors, battery, gyro, touchpad, and lightbar depend on browser, OS, connection mode, and controller firmware.

Vibration / Rumble Test

Modern Xbox, PlayStation, and many 8BitDo-style controllers use two rumble motors: a light high-frequency motor and a heavy low-frequency motor. Test each one separately before testing the combined mix.

Light / high-frequency motor 50%

Heavy / low-frequency motor 50%

Duration 600ms

Vibration isn't supported in this browser (Firefox/Safari). Try Chrome or Edge.

This test runs entirely in your browser using the standard Gamepad API. No input data is collected or uploaded.

Also test your Mouse Buttons, check your Input Latency, read the controller stick drift guide, or learn what the Hz panel means in our controller polling rate test guide.
