Why this tool is useful
Use this tester to find a button that does not register, an analog stick that fails to return near zero or a controller that the browser cannot see.

Gamepad Input Tester
Inspect browser-visible gamepad buttons, analog axes and connection state during a short bounded local polling session.
Ready. Your working data stays in this browser.
How it works
The page polls navigator.getGamepads inside requestAnimationFrame, formats only the current button and axis values and stops after the bounded test window or when cleared.
Practical example
Connect a controller, press a face button and move both sticks. The report identifies the gamepad slot, pressed button indexes and signed axis values exposed by the browser.
Validation
The test reports only browser-observable events and measurements; it does not invent hidden hardware health, temperature or manufacturer specifications.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
