ControllerTest

What is ControllerTest?

ControllerTest is a free browser tool for checking gamepads and controllers. It helps you see whether buttons, sticks, triggers, vibration, polling stability, and stick drift are working the way they should. You can connect a controller over USB, Bluetooth, or a 2.4G dongle, run a full health check, and review a simple report with useful metrics like deadzone suggestions and circularity. It also includes specialized tests for drift, polling rate, vibration, and trigger range, plus export options for sharing results or keeping repair notes. Everything runs locally in your browser, so there is no login required.

Key features

• Checks buttons, sticks, triggers, and vibration support.
• Measures stick drift and suggests a starting deadzone.
• Estimates polling rate, jitter, and connection stability.
• Tests circularity to spot uneven stick gate movement.
• Generates exportable health reports, JSON, CSV, and cards.
