Gamepad Tester is a free portable tool for Windows 10 and 11 that shows exactly what your controller is doing. Plug in an Xbox pad, Switch Pro, PlayStation controller (via driver) or any generic XInput gamepad: buttons light up the moment you press them, both sticks report live X/Y values, and the triggers are drawn as bars from 0 to 255.
That makes the usual faults obvious in seconds. Stick drift shows up as values that never return to zero when you let go. A stuck button, a dead zone that grew too large, a trigger that stops short of full travel - all of it visible instead of guessed at. A timestamped log records every press, so an intermittent fault can be proved to a seller or a warranty desk. Both vibration motors run from a slider to check the rumble hardware.
One file, no installer, no admin rights, no ads. Read-only by design: it reads controller state and never emulates input, so it cannot interfere with a game.
