Online Gamepad Controller Checker & Joystick Tester

The Gamepad Controller Checker is a free browser-based tool that lets you test, visualize, and calibrate any game controller online. Whether you’re using an Xbox controller, PlayStation DualShock or DualSense, Nintendo Switch Pro controller, or a generic PC gamepad, this tool shows your joystick, trigger, and button inputs in real time. There’s no need to download software, drivers, or calibration utilities — everything runs directly in your web browser.

Modern browsers such as Chrome, Edge, and Firefox support the Gamepad API, allowing websites like this one to detect your controller instantly. That means you can plug in or pair a controller, press any button, and immediately see how each input is registered. It’s fast, private, and perfect for diagnosing controller issues or confirming that everything works before you start gaming.

What the Gamepad Controller Checker Does

This online tool acts as both a controller input viewer and a calibration tester. When your controller connects, you’ll see two live joystick pads on the screen. Moving the analog sticks shifts a dot within each circle, representing the X and Y axis movement. Pressing buttons highlights them on the digital controller layout, and pulling triggers shows the level of pressure being applied.

Because it uses standard browser APIs, the Gamepad Controller Checker doesn’t send any data to a server — all processing happens locally on your device. It’s completely private and secure. This makes it a reliable way to test sensitive hardware like controllers without installing any unverified applications.

You can use it to confirm that both joysticks are accurate, the triggers respond properly, and the buttons register with no delay. If your joystick drifts or fails to return to center, you’ll see that visually in the interface.

How the Controller Tester Works

The tool works by listening to your device’s input signals via the Gamepad API. When you move a joystick, press a trigger, or push a button, those inputs are translated into numerical values between -1 and 1. The app takes those values and displays them as movement on the screen — for example, up and down for vertical axis, left and right for horizontal axis, and highlighted states for buttons.

The joystick tester portion also allows you to see whether your controller has a deadzone issue or drifting analog sticks. If the dot doesn’t sit perfectly in the center when your joystick is untouched, that’s a sign your controller may need calibration or repair.

There’s also a vibration test feature that activates both rumble motors so you can check if haptic feedback is functioning. It’s a quick and easy way to test if your controller’s vibration motors are still responsive.
