How do I test an Xbox controller for stick drift?

Release both sticks and watch the dots. Values that stay above about 0.05–0.1 without touching the stick point to drift.

Why do the triggers show as axes?

Some connections report LT and RT as analog axes instead of buttons. The raw axis list shows them either way.

Is the Xbox Controller Tester free to use?

Yes. Xbox Controller Tester is completely free with no sign-up, no install and no usage limits.

Is anything recorded or uploaded?

No. Xbox Controller Tester runs entirely in your browser — nothing is sent to a server, and nothing is saved unless you choose to download it.

Does it work on mobile?

Yes. It works in modern browsers on desktop, Android, iPhone and iPad. Allow access when your browser asks, and use the latest version of Safari, Chrome, Edge or Firefox.

Xbox controllers use the standard gamepad mapping in most browsers, so buttons are labeled A, B, X, Y, LB, RB, LT and RT, with View and Menu in the middle.

Xbox Controller Tester is part of a free, privacy-first toolkit. It uses your browser's built-in device APIs, so it starts instantly with nothing to install — and nothing you type, say or show ever leaves your device.

Because xbox controller tester works without any sign-up or installation, you can use it as often as you like and it's always available — on desktop or mobile, and even offline.
