Looking for a reliable way to test your controller? OnlineGamepadTester is one of the best free online controller testing tools for checking buttons, sticks, triggers, drift, and vibration.
Gamers use this tool before buying used controllers, after repairing hardware, or before competitive matches.
OnlineGamepadTester is built using the modern Browser Gamepad API, supported in all major browsers. When you connect a controller using USB or Bluetooth, the browser begins reading raw input data at up to 60 frames per second.
All processing happens locally on your device. No controller input data is sent to any server. This makes OnlineGamepadTester a fast, private, and secure controller tester online.
The tool continuously polls your gamepad, extracts joystick axis values (-1.00 to 1.00), button states, and analog trigger pressure. It then visualizes this data using moving stick knobs, trigger bars, and highlighted buttons.
Stick drift is calculated as the maximum absolute axis value.
If drift exceeds 0.05,
the indicator changes color.
Latency is estimated by measuring the time between
a button press and screen update.
Vibration testing uses the
vibrationActuator or
hapticActuators interface when available.
Simply plug in your controller and start testing instantly.
