How to Use
Connect Your Controller
Plug in your USB gamepad or connect via Bluetooth. The browser will automatically detect your controller.
Press Any Button
For security reasons, browsers require you to press a button before accessing gamepad data. Press any button on your controller to activate it.
Test All Inputs
Check buttons, analog sticks, triggers, and D-pad. The visual display will update in real-time as you press buttons and move sticks.
Test Vibration
Use the vibration test section to verify your controller's rumble motors are working correctly.
Features
Button Testing
Test all controller buttons including face buttons (A/B/X/Y), shoulder buttons (LB/RB), triggers (LT/RT), stick clicks, and special buttons.
Analog Stick Analysis
Monitor analog stick position with precise X/Y coordinates. The circular visualizer shows exact stick position and helps detect drift issues.
Trigger Monitoring
Analog triggers display their pressure value from 0.00 (released) to 1.00 (fully pressed). Essential for racing games and shooters.
Vibration Testing
Test weak and strong rumble motors independently. Adjust duration and intensity to verify both vibration motors function correctly.
Circularity Test
Analyze joystick precision by testing how accurately the stick moves in a circle. Detects uneven wear or calibration issues.
Circularity Test Guide
The circularity test measures how accurately your analog stick can trace a perfect circle. This helps detect mechanical wear, calibration problems, or manufacturing defects that may affect gameplay precision.
Enable the circularity test toggle in the Deadzone Analysis section
Slowly rotate the analog stick in a full circle along the outer edge

Understanding Error Values
- Less than 10% — Excellent precision, stick is in great condition
- 10% - 20% — Acceptable, minor wear or calibration drift
- More than 20% — Poor precision, consider recalibration or replacement
Tips
- If your controller isn't detected, try using Chrome or Edge which have better gamepad support
- Wireless controllers may have slight input lag compared to wired connections
- Some generic controllers may show as 'Non-Standard' mapping - raw mode helps identify button indices
- Stick drift is normal wear on analog sticks - small values near center indicate drift
- Nintendo Switch Pro Controller works but button mapping may differ from Xbox layout
Supported Controllers
Xbox One/Series X|S Controller
