DEVICE TESTS TOOL
Gamepad Tester
Test controller buttons and analog sticks with live visual feedback.
Connect a gamepad or controller and press any button to activate it — most browsers only "see" a gamepad after its first button press or stick movement.
About this tool
Test a game controller's buttons and analog sticks right in the browser — every button lights up when pressed (with its analog value for triggers), and each stick's axes are shown as live bars. Useful for checking a new or old controller for worn sticks, stuck buttons, or drift before a game blames your skills instead.
Frequently asked questions
- Why doesn't my controller show up immediately?
- The Gamepad API only registers a controller after you press a button or move a stick on it at least once — just connecting it over USB or Bluetooth usually isn't enough to trigger detection.
- What is "stick drift" and how would I see it here?
- Drift is when an analog stick reports movement even while resting untouched — watch the axis bars for a stick with the controller sitting still; if a bar doesn't sit dead-center at rest, that stick may be drifting.
- Does this work with Bluetooth and wireless controllers?
- Yes, as long as your operating system has already paired and recognized the controller — the browser sees it the same way regardless of USB or wireless connection, once the OS reports it as a connected gamepad.
