Pro Gamepad Tester

Pro Gamepad Tester is a free online diagnostic tool that helps gamers, developers, and controller repair enthusiasts test any gamepad directly in their browser with no download and no installation required.

The tool uses the Web Gamepad API to read raw input data from any connected controller and display it in real time. Users connect their controller via USB or Bluetooth, press any button to activate the tool, and immediately see live readings for every input their hardware produces.

What the Tool Tests

Thumbstick axis values for all four axes displayed as precise floating-point numbers, making it easy to detect stick drift at its earliest stage before it becomes visible in games.

Analog trigger values from 0.0 at rest to 1.0 at full press, revealing dead spots, value jumps, and return failures caused by internal wear on the trigger mechanism.

Button states for every input on the controller with instant visual feedback on each press and release, confirming hardware reliability independent of any game or software.

Supported Controllers

PS5 DualSense, PS4 DualShock 4, PS3 DualShock 3, Xbox One, Xbox Series X and S, Nintendo Switch Pro Controller, and any standard USB or Bluetooth HID gamepad.

Supported Platforms

Works on Windows, macOS, Linux, and Chromebooks in Chrome, Edge, Firefox, and Opera. No driver installation required for most modern controllers.

Who Uses It

Gamers diagnosing stick drift or button failures before deciding whether to repair or replace a controller. Competitive players configuring precise deadzone settings based on real hardware data. DIY repair technicians verifying their work before reassembling a controller. Game developers checking raw axis and button mappings during input system development. Buyers inspecting used controllers before purchase.

All input processing happens locally in the browser. No controller data is ever transmitted to any server. The tool is completely free with no account, no subscription, and no usage limits.
