What we build
The tester reads the browser Gamepad API locally and turns raw input into practical checks: live button mapping, analog stick drift, deadzone guidance, trigger travel, circularity, polling-rate estimates and vibration capability detection.
The site is designed as a tool-first experience. The test panel appears before long explanations, while methodology, limitations and troubleshooting stay close enough for users who need to validate a result.
- Controller health reports for screenshots, resale checks and repair notes.
- Device-focused pages for Xbox, PlayStation, Switch and generic PC controllers.
- Transparent browser limitations instead of hardware-level precision claims.
How results should be used
ControllerTest is useful for comparing one setup against another, finding obvious hardware problems and producing repeatable notes. It is not a lab instrument, firmware tool or manufacturer calibration utility.
Polling-rate values are browser-visible estimates. Vibration support depends on browser, operating system, driver and controller model. DualSense adaptive trigger resistance is not controlled through the standard browser API.
Independence
ControllerTest is not affiliated with Microsoft, Sony, Nintendo, Valve or any controller manufacturer. Product names are used only to describe compatibility and search intent.
