A free bench tool for anyone with a controller
Controller Test is a free online gamepad tester for Xbox, PlayStation, Nintendo Switch and generic HID controllers. It runs entirely in your browser using the standard W3C Gamepad API and WebHID, so nothing you press ever leaves your device.
Why we built it
Most controller testers online are cluttered with ads, gated behind installs, or send your input somewhere you cannot see. We wanted a quiet workbench that competitive players, repair techs and buyers of used pads could open, use, and close without a second thought. Every diagnostic here focuses on one job so you can pinpoint exactly what is failing.
How it works
Your browser exposes controller state through the Gamepad API once you press a button. We read that state at up to your display refresh rate, render it live, and never transmit it. Advanced tools such as PS controller calibration use WebHID, which requires an explicit device permission you can revoke at any time.
What you can do here
- Run a quick full-pad check on the home tester.
- Diagnose stick drift, verify every button mapping, or measure polling rate and latency.
- Test rumble motors with the vibration test.
