A complete guide to testing your game controller with Gamepad Tester. Press buttons, move analog sticks, pull triggers, and test vibration motors in real time, directly in your browser, with no downloads or sign ups needed.
Follow these four steps to thoroughly test every input on your controller and catch hardware issues before they affect your gameplay.
Connect your controller using USB or Bluetooth. The browser detects it automatically once you press any button, which is a privacy requirement of the Gamepad API rather than a bug.
Press each button one at a time in the Button Test and watch the matching indicator light up. Work through every face button, shoulder button, trigger, and D pad direction methodically.
Move each stick slowly through its full range and watch the live coordinate readout. A healthy stick at rest should read close to zero, any reading without touching it can point to drift.
Finish by checking vibration, reviewing your results, and using the deadzone and polling rate tools if you noticed anything worth a closer look.
Gamepad Tester works with any controller your operating system recognizes. Here are the most commonly tested controller families.
Full compatibility across Xbox controller generations over USB and Bluetooth, with buttons, triggers, and rumble motors accessible in Chrome, Edge, and Firefox.
Complete support for Sony controllers with full button mapping, analog trigger detection, and vibration testing. DualSense and DualShock 4 work best in Chrome and Edge.
The Switch Pro Controller and Joy Con pairs are recognized as standard gamepads over USB or Bluetooth, using the standard button layout for consistent testing.
Any HID compliant USB or Bluetooth controller is generally detectable, including popular third party brands. Feature availability depends on what the controller itself reports to the browser.

If your controller is not appearing or inputs are not registering correctly, work through these checks in order.
A controller connected before the page loaded may not be detected. Reload the page, connect your controller, then press any button.
Make sure your USB cable is firmly seated, or that Bluetooth is properly paired in your system settings. Try a different port or cable.
Chrome and Edge have the most complete Gamepad API support. Firefox works for most controllers, though vibration testing may not be available.
Some browsers prompt for gamepad access. If you see a prompt, allow it. If you denied it before, reset the permission in your browser site settings.
A low battery can cause intermittent disconnects and input lag. Charge fully or replace batteries, then reconnect and test again.
On Windows, open Device Manager and look for controller entries with a warning icon. Update the driver, or reinstall the manufacturer's software.
Compatible with all modern browsers. Chrome, Edge, and other Chromium based browsers offer the most complete support. All input data is processed locally in your browser, nothing is sent to any server.
