Test your controller for stick drift. Right in the browser.

The JoyCheck controller tester doubles as a stick drift test: rest the sticks, watch the live X and Y values, and a reading that sits away from 0.00 while your hands are off the pad is drift, read straight through the W3C Gamepad API with nothing sent to a server.

Stick drift is an analog stick that reports movement while you are not touching it, and a browser stick drift test is the fastest way to confirm it. The W3C Gamepad API[1] reports each stick axis on a fixed -1.0 to +1.0 scale where 0.0 is the neutral center, so a drifting stick has a clear signature: a steady nonzero value at rest. Connect the controller, rest it flat, and the number tells you what your hands cannot feel.

How do you test for stick drift?

You test for stick drift by reading the resting position of each analog stick on a browser tester. Set the controller flat, take your hands off both sticks, and watch the X and Y values: a steady reading away from 0.00 while you are not touching the pad is drift the game will read as movement.

Run it as a short protocol, not a single glance. Each step isolates a different way drift shows up, so together they separate a genuine fault from normal sensor noise.

1. Read the resting position. Rest the pad flat, hands off, and read X and Y. Healthy sticks flicker within about 0.02 of 0.00.
2. Check the deadzone crossing. Watch whether the resting value pushes past the neutral band. A value that crosses it is what a game reads as real input.
3. Hold for 30 seconds. Leave the sticks untouched for a full 30 seconds, because intermittent drift often appears only after the stick settles or warms up.
4. Re-verify after a fix. Once you clean, recalibrate, or replace the stick, read the resting value again to confirm it dropped back toward 0.00.

The online gamepad tester shows every value as it changes, so you can walk the four steps in under a minute.

How do I know if I have stick drift?

You know you have stick drift when the game moves without you: the camera pans on its own, a menu cursor slides, or your character walks while the sticks sit still. Those symptoms are the prompt to test, not proof on their own, because a low in-game deadzone can cause the same feel.

The confirmation is numeric. Rest the controller flat in a tester and read the resting value, and a steady offset above roughly 0.05 on either axis is drift rather than a game setting.

Test both sticks the same way. Drift usually starts on one stick, most often the left, so a clean right stick does not clear the left.

What resting value counts as stick drift?

As a rule of thumb on the normalized -1.0 to +1.0 scale, a resting stick within about 0.02 of 0.00 is healthy, 0.05 to 0.15 is treatable drift, and anything above 0.15 is a worn sensor. These are working bands from our own diagnostic testing, not a manufacturer specification, so read them as a guide rather than a hard line.

The single most useful number is not today’s reading but its trend. A value that holds steady is a calibration job; a value that climbs week over week is wear, and wear only ends with new hardware.

Can stick drift actually be fixed?

Stick drift can be masked, and sometimes cleared for a while, but rarely fixed for good in software. Recalibration re-centers the reported value, a deadzone bump hides a small offset, and compressed air with isopropyl alcohol occasionally revives a dirty stick.

Because drift is physical wear on the sensor, those fixes are temporary and the offset tends to return. The honest expectation is a few more weeks of play, not a cure.

A lasting fix is hardware. Replacing the stick module ends the drift, and a Hall-effect or TMR controller removes the wear mechanism entirely. The full repair ladder, cheapest to most durable, is in how to fix controller stick drift, and the mechanism behind it is covered in stick drift, explained.

Is there a website to check stick drift?

Yes. JoyCheck is a browser-based stick drift test: open the page, connect your controller, and it reads the live stick values through the W3C Gamepad API[2] with nothing installed and nothing uploaded. Because it reads the raw hardware report before any game applies a deadzone, it often shows drift earlier than an in-game screen does.

That is the difference from testing inside a game. A game shows you filtered input after its own deadzone, so a small drift stays hidden until it grows; the browser shows the unfiltered value the moment it appears.

It also runs anywhere a modern browser does, on Windows, macOS, Linux, and mobile, with no driver install, so the same test works across every device you play on.

What a browser test can and cannot tell you

A browser stick drift test reads exactly what your operating system reports for the controller, which is enough to confirm drift, measure how bad it is, and check whether a fix worked. What it cannot do is repair a worn sensor or open the controller, so it is a detection tool, not a repair tool.

Once the resting value confirms wear[3], the fix is hardware, and the path depends on your controller. Start with the platform calibration guides to rule out a soft center error, then move to a module swap if the offset returns.

For the platform steps, the PS4 controller calibration guide and the Xbox controller calibration guide cover the exact recalibration paths, PS5 controller stick drift covers the DualSense case, and the deadzone tester reads the resting and edge band you would tune around a mild offset.
