Compatibility depends on the actual controller, connection, operating system, browser and driver. A device appearing here is not a guarantee that every input or haptic feature is supported.

## Compatibility notes

### Xbox / XInput controllers

Browser result: Usually standard mapping

Best first test is USB on Chrome, Edge or Firefox.

### DualSense / DualShock

Browser result: Input support varies by OS

Adaptive trigger resistance is not controlled by the standard browser Gamepad API.

### Switch Pro / Joy-Con

Browser result: Mapping can vary

Use the live input grid to confirm actual browser button labels.

### Vibration / haptics

Browser result: Capability-detected

Games may rumble even when the browser cannot expose a compatible actuator.

### Polling rate

Browser result: Browser estimate

Useful for comparisons, not a USB analyzer or hardware certification reading.

Use this page when a controller does not appear, mappings look wrong, vibration is unavailable or a diagnostic result needs interpretation.

## Connection checklist

Most browser controller problems start before the test data arrives. Work through the simple checks first, then rerun the live input test.

- Connect the controller by USB for the first test, then compare Bluetooth or 2.4G later.
- Press any controller button after loading the page to wake the browser Gamepad API.
- Close games or launchers that may hold exclusive controller access.
- Try Chrome, Edge and Firefox if one browser does not expose the device correctly.
- Disconnect and reconnect the controller if the page still shows stale input.

## Interpreting common results

A small stick center offset is normal. The important question is whether the offset is large enough to move a game character or camera when the stick is untouched.

If a trigger never reaches the full range, test slowly several times. If the value remains capped, the issue may be hardware wear, driver mapping or platform-specific behavior.

- Use stick drift for center noise.
- Use circularity for outer-gate travel.
- Use polling rate only for same-browser comparisons.
- Use vibration results as capability detection, not proof that the controller motor is broken.

## Device guides

- [Xbox Controller Tester](https://controllertestonline.com/xbox-controller-test/): Test Xbox Series, Xbox One, Xbox Elite and Xbox-style PC controllers. Check A/B/X/Y, bumpers, triggers, sticks, D-pad, vibration support and export a health report.
- [PS5 Controller Test](https://controllertestonline.com/ps5-controller-test/): Connect your DualSense to test PS5 button input, stick drift and L2/R2 trigger travel. Follow the checks below to understand what each browser reading means.
- [Switch Controller Test](https://controllertestonline.com/switch-controller-test/): Test Switch Pro Controller and Joy-Con input in the browser. Check stick drift, circularity and button mapping before deciding whether a controller needs recalibration or repair.
- [Switch Joy-Con Drift Test](https://controllertestonline.com/switch-joy-con-drift-test/): Connect a Joy-Con or Switch Pro controller, leave the stick untouched, and measure center offset before checking deadzone and circularity.
- [Gamepad Mapping Test](https://controllertestonline.com/gamepad-mapping-test/): Use the mapping test to see which browser button index, axis and trigger value changes when you press each control on the gamepad.
