Pro Gamepad Tester is a free online tool that lets you test any controller directly in your browser, with no download and no account required.

Connect your PS5 DualSense, PS4 DualShock 4, PS3 DualShock 3, Xbox controller, or Nintendo Switch Pro Controller, press any button, and watch every input respond in real time.

Catch stick drift early by checking exact axis values at rest. Test trigger smoothness across the full range of motion. Confirm every button registers reliably with instant visual feedback.

Use it before a gaming session, after a repair, or before buying a used controller secondhand. The tool reads raw hardware data straight from your browser, so what you see is exactly what your controller produces.

Visit Pro Gamepad Tester and run your first test for free.
