Test Your Controller in the Browser

About Stick Drift Check

Stick Drift Check is a free, no-signup set of controller tests that run entirely in your browser using the Gamepad API. Connect an Xbox, PlayStation, Nintendo Switch Pro, or generic USB/Bluetooth controller, press any button so the browser can see it, and every tool on this site comes to life — no driver, no download, no account.

The five tools split cleanly by what you're trying to find out. The stick drift test measures each analog stick's resting position over a three-second window and flags DRIFT when a released stick wanders outside a small threshold. The deadzone visualizer plots both sticks against an adjustable deadzone ring so you can see whether a game would swallow that drift or not. The button test shows live pressed state for every button the pad reports, the trigger test gives analog travel bars for LT/RT and L2/R2, and the rumble test fires a haptic pulse at both vibration motors.

If you know exactly which pad is in your hands, start from its own page instead: the Xbox controller test, the PS5 controller test, the PS4 controller test the Switch Pro controller test and the Joy-Con drift test each run the same drift, button and trigger engine, with the resting values a healthy example of that controller reports and what its manufacturer will do about a worn one. The Joy-Con page is the odd one out by design: a single Joy-Con reports one stick, so it is measured and reported as one.

All detection and analysis happen locally on your device. No controller data leaves your browser unless you press Save this check on a drift result, and the privacy policy lists what that stores.
