Gamepad Tester
Test controller buttons and analog sticks in your browser. Sample resting offset, compare two sessions and print a local report. No download or upload.
Connect your controller, then press a button to let your browser detect it. Choose one controller and start a test.
Live preview only; start a test to record observations.
The browser exposes normalized input after driver processing. Resting offset is an observation, not proof of a faulty stick. No raw sensor latency or true USB/Bluetooth polling rate is measured. Controller names, inputs and reports stay in this page session.
Check a used controller or compare the same device before and after a change. Choose USB or Bluetooth as a label for your test; the browser does not reliably identify the connection type.
A repeatable controller check
Start the test, release the sticks and record a three-second resting sample. Then press each button and move the sticks through their range. Repeat the same actions after a change and compare the observations.
Input values are normalized by your browser and driver. Stick ranges and resting offsets are not a hardware diagnosis, a calibration certificate, raw sensor latency or true polling-rate measurement. Drivers may already apply a deadzone.
Standard mapping provides the familiar left/right stick pairs. For non-standard controllers, axes and buttons are shown by index; check your physical controls. Support varies by controller, operating system and browser. Keep this page visible while testing.
Sources and method
Frequently asked questions
- Does an offset prove stick drift?
- No. It reports what the browser observed while you chose to leave the sticks at rest. Driver settings, movement and sampling conditions affect the values.
- Are controller inputs uploaded?
- No. Names, axis samples, button observations and reports remain in this page session. Analytics receives only the tool ID and action type.
- Can I compare USB and Bluetooth?
- You can run the same test twice and label the connection yourself. This does not measure connection latency or true polling rate.
