Stick Snapback Test
This stick snapback test watches how an analog stick returns to center after you release it. Snapback/overshoot can matter in fighting games and precise camera control — this page keeps the check browser-side and honest.
Connect your controller
USB or Bluetooth. Press any button if nothing appears.
How to use this tool
- Connect your controller.
- Push a stick to an edge, then release cleanly.
- Watch the return path and overshoot readings.
- Repeat a few times for a fair comparison.
What the readings mean

Why snapback matters
If a stick overshoots past center, games can register opposite inputs. Results here are browser-side diagnostics, useful for comparison on the same machine — not laboratory-grade hardware measurement.
Next steps
Compare with the circularity test and joystick tester. For idle issues, use the stick drift test.
Compatibility and limitations
Requires analog sticks visible to the Gamepad API.
Hand release technique strongly affects outcomes. Keep method consistent when comparing controllers.
