About the Gamepad Tester
If a button seems stuck or a stick drifts, it helps to see exactly what your controller is sending. Connect an Xbox, PlayStation, Switch Pro or generic controller by USB or Bluetooth, press any button and this tester shows it live: every button lights up when pressed, triggers show how far they are pressed, and the sticks show their position as numbers and a bar. A stick that rests at 0.00 is healthy; a steady value means drift. If your controller supports it, you can also test the rumble motors. The page reads the controller through your browser's Gamepad feature, so nothing is installed and nothing is sent anywhere.

How to use the Gamepad Tester
- 1Connect your controller by USB or Bluetooth.
- 2Press any button so the browser notices it.
- 3Press each button and trigger and watch it light up.
- 4Leave the sticks alone and check that their values are near zero.
- 5Press Test vibration if it is shown.
What the numbers mean
Each button reports either pressed or not, and analogue buttons such as triggers also report a value from 0 to 1. Each stick has two axes, one for left and right and one for up and down, with values from -1 to 1 and 0 in the middle. A stick at rest should read very close to 0 on both axes.
If an axis jumps around by itself or rests away from zero, the stick may be worn or dirty. Game settings often have a dead zone to hide this, but a bigger fault means the stick should be cleaned or replaced.
Troubleshooting
- Try another cable or USB port.
- Charge the battery of a wireless controller.
- Close other apps that may use the controller.
- Reconnect Bluetooth by removing and pairing the controller again.
- Clean around stuck buttons with a little isopropyl alcohol and a soft cloth.
- Update the controller's firmware if the maker offers it.

Frequently asked questions
Why doesn't my controller show up?
Browsers only reveal a controller after you press a button on it. Press any button after the page has loaded. Also check the connection, try another USB port or cable and make sure no other app has grabbed the controller.
How do I check for stick drift?
Leave both sticks alone and look at the axis values. They should be within about 0.05 of zero. A steady value such as 0.15 means the stick is drifting.
Why are the buttons named differently?
Controllers report numbered buttons. For controllers with the standard layout the tester shows the usual Xbox and PlayStation names, while others only show the numbers.
Does it work with Bluetooth controllers?
Yes, if your computer or phone has paired the controller and the browser can see it. On some systems, you must pair it in the system settings first.
Can I test the triggers?
Yes. Triggers are shown as buttons with a percentage while they are partly pressed.
Why doesn't vibration work?
Not every browser and controller supports vibration through the web. Chrome and Edge do for many controllers.
Does it work on a phone?
It does on Android with a Bluetooth controller in Chrome. iPhones support some controllers in Safari but the options are limited.
