Quick answer
What Controller Stick Drift Test tells you
Watch analog-stick values around center and compare them with an adjustable reference deadzone.
- Observed here
- Live X and Y axes, Center-position plot, Adjustable deadzone.
- How to interpret it
- Nonzero centered axis values show what the browser receives while the stick is at rest. A small offset is not automatically a fault; dead-zone and calibration behavior differ between applications.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Controller identity and input values are displayed locally and are not transmitted or stored.
Useful next comparison: Release the stick, repeat the centered observation and compare the same axis in the target application before adjusting its dead zone.
Understanding the result
What a result means
The resting X/Y offset is compared with an adjustable reference deadzone. Small non-zero values can be normal; drift becomes practically relevant when the repeated resting offset exceeds the deadzone used by a game.
Confirm the pattern by repeating live x and y axes. Results reflect events and values exposed by this browser.
How to use this test
- Read the privacy and compatibility notes.
- Start the test and interact only inside the marked test area.
- Repeat the action several times and compare the live indicators.
- Use the troubleshooting section before deciding that hardware is faulty.
What this test checks
- Live X and Y axes
- Center-position plot
- Adjustable deadzone
- Maximum observed offset
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
The result is a reference, not a warranty or repair decision.
Common problems and troubleshooting
Release the stick gently, collect several resting samples and rotate it through the full range before returning to center. Compare another browser, wired mode and the game’s own deadzone before considering calibration or service.
- Repeat the same observation. Focus the test surface and repeat “Live X and Y axes” three times under the same conditions.
- Change one condition. Compare “Center-position plot” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
Axis precision and mapping come from the Gamepad API and differ by controller firmware and browser. The page shows raw normalized values but cannot write calibration data back to the device.

Frequently asked questions
Is this Controller Stick Drift Test free?
Yes. The test works without an account, download or payment.
Is my test data uploaded?
Controller identity and input values are displayed locally and are not transmitted or stored.
Does this result prove my hardware is faulty?
No. It shows what the browser can observe. Repeat the test, compare another browser or device, and seek qualified support when the result matters.
