DeviceXA Gamepad Tester is a fast, browser-based tool to diagnose game controllers without any installation. It provides real-time input visualization for buttons, triggers, and analog sticks, helping you quickly identify issues like stick drift, dead zones, and unresponsive inputs. Unlike many tools, it runs entirely in the browser, is lightweight, and works instantly across most standard controllers.
