Gamepad Tester

Elegant Matter Gamepad Tester presents controller input through a browser. The page waited for a connected controller during this first look. Hardware input and measurement accuracy are Not reviewed. Connect an Xbox, PlayStation, Nintendo or generic USB or Bluetooth controller and press a button, since some browsers only expose a controller after you interact with it. The input map lights up each control as you press it, using a PlayStation/DualSense, Xbox, Switch Pro or generic layout chosen from the device name or picked by hand. The button test marks every input you've tried and keeps each trigger's peak value, so a missed control is easy to spot. If the browser doesn't report the standard mapping, the page says so and recommends trusting the raw button numbers instead.

The documentation describes a five-second resting-stick test and an optional full-range sweep. It explains center offset, a neutral envelope, and maximum movement without treating one percentage as a universal pass or fail. Browser mapping and a game's deadzone affect how a result should be interpreted. The full-range sweep asks you to push a stick to its edge and rotate it two or three times, then reports coverage across 24 directions with minimum, median and maximum reach. Diagonal values above 100% can be normal, because the browser normalizes the X and Y axes separately. A session summary lists untested inputs, drift and sweep results and vibration, and you can copy it, which can help when you need to describe a fault.

The page says its deadzone control is a visual reference, not calibration. Browser input also differs from physical stick travel and end-to-end latency. Missing web vibration support does not establish broken hardware. Compare a familiar controller over USB and Bluetooth to see whether the connection changes the result. Vibration behavior and the site's local-processing claim are Not reviewed. Vibration can be tested on the strong and weak channels separately, and the page asks whether you felt it. The tool is free, needs no account and says it runs in your browser with data staying on your device. It comes from Elegant Matter, an independent technology publication, whose privacy policy, updated October 20, 2026, says the policy would be updated if a future tool needed remote processing, an account or stored inputs.
