ControllerTest Quick Check

Test gamepad buttons, sticks, triggers, drift and export a local controller report.

ControllerTest Quick Check is a local gamepad diagnostic tool for Chrome. Open the toolbar popup for a fast button, trigger and stick check, or open the full tester tab for drift sampling, circularity coverage, polling-rate estimates, vibration capability checks and JSON/CSV report export. The extension is useful for checking Xbox, PlayStation, Switch Pro, Joy-Con and generic PC controllers before gaming, repair, resale or support troubleshooting. Results are browser-level diagnostics, not hardware-lab certification. Controller readings are processed locally in your browser. The extension does not upload controller diagnostic data.
