Connect a controller (USB or Bluetooth), then press buttons and move sticks to see real-time input. Works best in Chrome/Edge on desktop. Results vary by device and browser.
A gamepad test is a diagnostic tool that checks your game controller's functionality in real-time—buttons, triggers, and analog sticks—while detecting stick drift issues. Essential for troubleshooting controller problems, testing used controllers before buying, or verifying that repairs work correctly. This browser-based tester works with Xbox, PlayStation, and generic controllers with no software installation required.
Our gamepad tester uses the browser's Gamepad API to communicate directly with your controller. When you connect a gamepad via USB or Bluetooth and press any button, the browser detects it and starts polling the controller state at high frequency. We read button states (pressed or released), analog stick positions (X and Y axes from -1.0 to 1.0), and trigger values (0.0 to 1.0). All processing happens locally in your browser—no data is sent to any server, and no plugins or downloads are required.
This browser-based test accurately detects button presses, stick positions, and trigger values for most standard controllers. However, there are limitations: Haptic feedback (vibration, adaptive triggers) cannot be tested through the Gamepad API. Polling rates may vary between browsers (Chrome typically offers the best support). Some third-party controllers may not be fully compatible. For professional-grade hardware diagnostics or warranty claims, manufacturer tools may provide more detailed results.
If analog stick values don't return to 0.00 when released, you have drift. Minor drift (±0.05) can be compensated with deadzone settings in games. Significant drift (±0.15+) typically requires repair or replacement.
All buttons should light up immediately when pressed and return to inactive when released. Delayed response or buttons that stay active indicate potential switch issues.
Triggers should smoothly report values from 0.0 (released) to 1.0 (fully pressed). If your triggers don't reach full range, they may be worn or need calibration.
