Guides

Practical help for controller testing — written for real troubleshooting, not keyword pages.

These guides explain how to test a gamepad in the browser, what stick drift and deadzone readings mean, and how to troubleshoot common detection and vibration issues. Use them with the live tools on this site— open a guide when you need context, then confirm what your controller is doing on the matching tester page.

Start with a full pass on the Controller Tester if you are not sure where the problem is. For idle stick movement, use the Stick Drift Test and the deadzone guide. If the pad never appears, read Controller Not Detected and check Controller Detection before you assume the hardware is broken.

What you will find here

  • Step-by-step browser testing for buttons, sticks, triggers, and rumble
  • Honest notes on Gamepad API limits (including when vibration may be missing)
  • PC connection tips and drift vs deadzone explanations without repair hype
  • Links from each guide to the live tool that matches the topic

How to Test a Controller in Your Browser

A clear checklist to verify buttons, sticks, triggers, and connection with a free gamepad tester.

How to use these guides with the tools

Read the guide first when you need a checklist, then keep the related tester open in another tab. Compare what the page shows with what you feel on the pad. If results look fine in the browser but a game still misbehaves, the issue may be game settings, drivers, or a platform overlay—not always the controller itself.
