Gamepad & Controller Stick Drift, Circularity & Vibration Tester
HTML5 Gamepad APITest game controllers and gamepads for stick drift, thumbstick circularity error, button latency, and vibration rumble directly in your browser. Supporting Xbox, PlayStation DualSense, Nintendo Switch Pro, and generic USB/Bluetooth controllers via the W3C Gamepad API with zero software downloads.
Gamepad & Controller Stick Drift, Circularity & Vibration Tester
Test PS5 DualSense, Xbox, and Switch controller stick drift, circularity error %, triggers, and rumble.
Interactive Gamepad & Controller Stick Drift, Circularity & Vibration Tester Workspace
A real-time, 100% in-browser gamepad diagnostic benchmark powered by the HTML5 Gamepad API. Detect analog thumbstick drift down to 0.0001 precision, measure outer-rim Stick Circularity Error % across 36 angular sectors, inspect L2/R2 trigger pressure linearity, verify all 16 button switches, and test dual-motor haptic rumble.
How This Tool Works (100% Client-Side Engine)
The tool listens to window.addEventListener("gamepadconnected") and runs a 120Hz requestAnimationFrame polling loop querying navigator.getGamepads(). It captures raw button pressed and value floats alongside axes[0..3] coordinates, rendering visual stick positions onto an HTML5 circular canvas.
Step-by-Step Guide
Connect Game Controller
Plug in your controller via USB cable or pair via Bluetooth, and press any button to wake the Gamepad API.
Inspect Resting Drift & Buttons
Leave sticks untouched to verify if coordinates remain within resting deadzone, and press all buttons to verify response.
Run Circularity & Vibration Tests
Rotate thumbsticks in a full circle to compute circularity error, and click Trigger Vibration to test haptic motors.
Why Use This Tool: Privacy & Performance
Analog stick drift—caused by potentiometer wear, debris, or spring fatigue in thumbstick assemblies—is one of the most frustrating hardware defects affecting console and PC gamers. Diagnosing subtle stick drift or calculating axis deadzones traditionally required launching games or installing vendor-specific desktop software. ToolByte Gamepad Stick Drift & Input Tester uses the native W3C Gamepad API built into modern web browsers to inspect controller inputs in real time. Connect your controller via USB or Bluetooth, and the tool visualizes raw axis coordinates (-1.0 to +1.0), calculates circularity error percentages on analog sticks, detects phantom inputs outside resting deadzones, tests analog trigger pressure curves (L2/R2), and triggers dual-motor haptic rumble tests with zero external telemetry.
Common Use Cases & Workflows
Diagnosing Analog Thumbstick Drift
Detect whether left or right analog sticks fail to return to pure zero center (0.000, 0.000) when released at rest.
Measuring Thumbstick Circularity Error %
Rotate thumbsticks in full 360-degree sweeps to calculate average error percentages against a perfect geometric circle.
Testing DualSense & Xbox Vibration Rumble Motors
Trigger low-frequency and high-frequency haptic vibration pulses to confirm motor actuator functionality.
Verifying Analog Trigger Pressure Sensitivity
Check analog trigger graduation from 0.00 to 1.00 to confirm smooth, linear throttle and brake response in racing games.
