About stickdriftest

stickdriftest is an independent browser tool for observing controller sticks, buttons and triggers. It is not affiliated with Sony, Microsoft, Nintendo or any controller manufacturer.

How the resting stick drift test works

After a three-second countdown, we observe ten seconds of browser-visible axes. The mean offset is time-weighted; peak offset is the largest observed distance from center. A gap over 250 milliseconds, focus loss, invalid axes or a disconnection interrupts the check. We apply no deadzone, automatic centering or smoothing to those calculations.

What browser controller tests cannot tell you

The browser’s observations are not a hardware polling-rate measurement. Drivers, firmware and games can change the inputs before you see them. We cannot diagnose damage, repair a stick or guarantee how a controller behaves in a game.

Controller compatibility and current status

The drift and button tools are prototypes. Xbox, PS5 and PS4 pages provide setup guidance and the shared input tester, not verified device compatibility. Physical controller checks are pending. Their inclusion in search does not certify hardware support.
