Controller Test

What is Controller Test?

Controller Test is a free, local-only gamepad diagnostic tool that runs right in your browser. It helps you check buttons, stick drift, triggers, vibration, latency, polling rate, and more for Xbox, PlayStation, Switch, and generic controllers. The site is built for quick checks, repair work, and buying used controllers with confidence. Everything happens on your device, so nothing is uploaded or tracked. You can open focused test pages for each issue and get clear guidance on what the results mean and how to fix common problems.
