About this gamepad tester

Gamepad drift robs precision and turns perfect runs into frustrating misses. This responsive deadzone tester gives you a lab-grade dashboard without bulky downloads. It instantly detects any Gamepad API compliant controller, visualizes stick travel with dynamic heat bars, and spotlights drift that exceeds your chosen tolerance. Because the tool runs entirely client-side, zero gameplay data leaves your device, making it ideal for esports training rooms, classrooms, and repair benches where privacy matters.

How to use

Start by connecting your USB or Bluetooth controller, then wake it with a button press. Adjust the deadzone slider to mirror your console or PC settings. Move each stick slowly through its range; green highlights confirm every direction clears the threshold while red flags expose unwanted drift. Tap “Add live snapshot” whenever you want to bookmark a reading—each snapshot records peak axis deviation, active buttons, and your optional note so calibrations stay organized. Once you are satisfied, export a CSV report or copy the preset link to reproduce the test on another machine.

Pro calibration tips

Warm controllers for five minutes before testing so lubricants stabilize. If sticks fail to return inside ±0.08 after repeated rotations, raise deadzones incrementally until drift disappears, then log the results to track wear. For competitive shooters, consider separate presets for hip-fire and scoped sensitivity—sharing the preset link with teammates keeps your squad synchronized. Pair this tool with your platform’s firmware updates; rerun diagnostics after each update to confirm manufacturer deadzone changes align with your preferences.
