About GamePad Gauge

GamePad Gauge provides free, browser-based tools for testing game controllers and analog sticks. There's nothing to install and no account to create — connect a controller, open a tool, and start testing.

The site currently includes a general-purpose Gamepad Tester, a focused Stick Drift Test, and a Controller Deadzone Test for measuring and tuning deadzone thresholds. All three share the same underlying browser Gamepad API implementation.

How it works

Every tool on this site uses the standard Gamepad API built into modern browsers to read your controller's button and analog stick state directly on your device. Testing happens entirely in your browser — no controller input is uploaded to any server.

Why we built this

Diagnosing a controller issue — a worn button, a drifting stick, an unclear deadzone setting — usually means digging through settings menus or installing extra software. This site aims to make that diagnosis quick and accessible from any browser, for free.
