Gamepad-Tester – Controller online testen

Connect a controller by USB or Bluetooth and press any button. The tester shows every button and axis live, measures stick drift, suggests a deadzone and lets you test vibration. It runs entirely in your browser: nothing is installed, uploaded or stored.

Drück eine beliebige Taste am Controller, um zu starten.

      How to use the gamepad tester

      1. Connect your controller with a cable or pair it over Bluetooth.
      2. Press any button: browsers only show a controller after the first button press, for privacy.
      3. Press each button and move both sticks. Pressed buttons light up on the diagram and in the raw list.
      4. To check drift, let go of both sticks for a few seconds and read the "max at rest" value.

      Reading the results

      Buttons show a value from 0 to 1; analog triggers move smoothly between them. Axes go from -1 to 1, with 0 in the centre. If the mapping says standard, the diagram matches the usual Xbox-style layout; otherwise only the raw list is reliable, because the browser does not know which physical button is which.

      Stick drift and deadzone

      A worn or dirty stick does not return exactly to the centre, so a game sees small movements you did not make. The tester records the largest value a stick reports while you are not touching it. Values under about 0.05 are normal. The suggested deadzone is that value plus a small margin: set a deadzone at least that large in your game to hide the drift.

      Update rate

      The browser reports a new timestamp whenever the controller sends a changed state. Move a stick continuously to see the approximate update rate. It is limited by the browser and the screen refresh rate, so treat it as a rough guide, not a lab measurement.

      Gamepad-Tester: Fragen und Antworten

      Why isn't my controller detected?

      Press a button first: browsers hide controllers until you press one. If it still does not show, reconnect the cable or re-pair Bluetooth, close other apps that use the controller (such as game launchers), and try a Chromium-based browser like Chrome or Edge. Some controllers need to be in the right mode (for example XInput) to appear.

      Does it work with PS5, PS4, Xbox and Switch Pro controllers?

      Usually yes. Xbox, DualSense (PS5), DualShock 4 (PS4) and Switch Pro controllers work in current desktop browsers over USB or Bluetooth. Whether the browser uses the standard layout depends on the browser and operating system; if it does not, the raw list still shows every button and axis.

      How do I test for stick drift?

      Move both sticks, then let go and wait a few seconds. The "max at rest" value is the largest reading while the stick was untouched. Around 0.05 or less is normal; a clearly higher value means drift, and the suggested deadzone tells you how large a deadzone to set in your game.

      Why doesn't vibration work?

      Vibration needs a controller with rumble motors and browser support for the Gamepad vibration feature. Chromium-based browsers such as Chrome and Edge support it for many controllers; support in other browsers varies. If the button is greyed out, your browser does not offer vibration for this controller.
