What Does Gamepad Tester Check?
Gamepad Tester is a free online controller testing tool that works directly in your browser using the browser Gamepad API. It detects any connected USB gamepad or wireless controller instantly without requiring any software download or installation. Once your controller is detected, the tool displays real time feedback for every button press, analog stick movement, and trigger pressure. It works as a complete controller input tester for diagnosing hardware issues before or during gaming sessions.
Supported Controllers
This gamepad tester supports all major gaming controllers including PS4 DualShock, PS5 DualSense, Xbox One, Xbox Series X and S, Nintendo Switch Pro Controller, and most generic USB PC gamepads. Any controller that is recognized by your browser through the standard Gamepad API will work automatically. It functions as both a PS4 controller test tool and an Xbox controller tester without any additional setup required.
How To Use This Tool
Using this joystick tester online is simple. First connect your controller to your PC via USB cable or pair it via Bluetooth. Once connected press any button on your controller to wake it up and allow the browser to detect it. The tool will immediately show all available buttons, analog sticks, and triggers. Press each button to see it light up on screen. Move your analog sticks to check for stick drift or unresponsive zones. Press the triggers to verify pressure sensitivity is working correctly. This makes it ideal for gamepad button checker tasks and pre-game controller calibration checks.
Understanding Your Results
When a button lights up green it means the input is being detected correctly. If a button does not respond it may indicate a hardware fault or connection issue. Analog stick coordinates show exact position values — if values change without you touching the stick this confirms joystick drift. Trigger bars show pressure as a percentage from zero to one hundred. This tool is particularly useful for identifying gamepad not working issues and checking controller input accuracy before competitive gaming. No personal data is collected. Everything runs entirely inside your browser.
