    WHY WE BUILT IT

    Less guessing.
    More getting back to the game.

    A character moves on its own. A trigger feels inconsistent. A new controller looks fine, but you want to check it before your next match.

    ControllerTester brings those first checks into one approachable place. See the input, understand the limits of the measurement and find a useful next step.

    Use it alongside DS4Windows and DualSenseX when checking how a controller or remapping profile appears to your browser.

    Controller testing questions, answered.

    How do I test my controller online?

    Connect it to your computer, open this page over HTTPS, focus the browser tab and press a controller button. When the browser exposes the gamepad, the tester displays its buttons and axes.

    Which controllers can I test?

    Any gamepad exposed through your browser’s Gamepad API can show raw inputs. Named stick and trigger diagnostics require the standard mapping. PlayStation, Xbox and Switch-style labels are provided; availability varies by browser and connection.

    Can this detect stick drift?

    The resting-stick test measures movement reported while you leave both sticks untouched. Firmware or remapping software may already filter that movement, so a zero reading is not proof that a physical stick is perfect.

    Can a website fix stick drift?

    This tester measures input. It does not repair hardware or change calibration. A deadzone in your game or controller software can hide small movements, but it also reduces sensitivity near the centre.

    Why is vibration unavailable?

    The browser may expose button and axis input without exposing a compatible vibration actuator. Try a supported browser or connection; lack of browser rumble does not by itself mean your controller is faulty.

    Does the tester measure controller input lag?

    No. Browser input snapshots cannot by themselves establish physical polling rate or end-to-end latency. This tester reports the inputs it observes and does not label animation timing as controller latency.

    Are my test readings uploaded?

    The tester code processes input on your device. It only saves a snapshot to browser storage when you choose, or creates a report for you to download. See the tester data page for the distinction between these readings and normal website requests.

    A LITTLE GUIDANCE GOES A LONG WAY

    Give your controller a checkup.

    Work through the buttons, triggers and sticks, then keep a record of what you observed.
