About
Ultimate Controller is a free gamepad tester for checking PS5, PS4, Xbox Series X|S and Xbox One controllers right in your browser. No download and no account.
It's an independent project, built to be a cleaner, more useful controller tester. Along with showing every button, it measures stick drift and gives you real deadzone numbers to use in your games.
What it does
- Live view of every button, trigger and stick
- A checklist so you know every input has been tested
- Stick calibration with deadzone and range previews
- Rumble testing on controllers and browsers that support it, including the trigger motors on Xbox controllers where the browser allows it
- Automatic detection of PS5, PS4, Xbox Series X|S and Xbox One controllers
