Gamepad Tester

How to test your controller

1. Connect your controller with USB or Bluetooth, then press any button so the browser detects it.
2. Press every button and trigger, and move both sticks through their full range.
3. Let go of both sticks for a second to check for stick drift.
4. Run the vibration and polling rate tests if you want to check those features too.

What each test checks

• Controller info shows the controller it detected and the number of buttons and axes it reports.
• Triggers show how far each trigger is pressed, from fully released to fully pressed.
• Left stick and Right stick show the position of each stick and its movement.
• Stick drift and range checks whether a stick rests at zero, and whether it moves in a smooth circle.
• Buttons lights up each button as you press it, so you can spot a button that does not register.
• Vibration lets you test the light and heavy motors, if your controller and browser support them.
• Polling rate estimates how often the controller reports to the browser.
• Double-press check flags a button that registers a second press too soon after release.
• Axes shows the raw value of each axis, which is useful for technical checks.

Stick drift: what to look for

Stick drift means a stick reports movement when you are not touching it. Let go of both sticks and check the resting position. A good stick rests close to zero. A resting offset above about 0.10 is drift, and games may move your character or camera on their own.

To check the range, roll each stick slowly around its outer edge a few times. The shape should look like a circle. Under 10% error is normal. A much larger error suggests a worn or uneven stick.

Compatibility

• Works with Xbox, PlayStation (DualSense and DualShock), Nintendo Switch Pro and most other controllers in Chrome, Edge and Firefox. Safari supports fewer controllers.
• Several controllers can be connected at once. Choose the one you want to test with the controller buttons on the page.
• If buttons look swapped or some are missing, the controller may be in a different mode, such as DirectInput instead of XInput, or it may need its own app. Try a different connection, USB or Bluetooth.

Limits of a browser test

• Browsers cannot read motion sensors (gyro), touchpad movement, adaptive trigger resistance, the light bar or the headset jack, so these cannot be tested here.
• The PlayStation touchpad click and most Home buttons do work.
• Browsers check controllers only a limited number of times per second, often about 250, so the polling rate estimate may read at that limit.
