From the tool guide: common questions about Gamepad & Controller Tester
The items below are not posts by community members. They come from the written guide for this tool and are here to get a conversation started. Use “Ask a follow-up” to open a thread about any of them.
Why does the tester not see my controller?
Browsers hide gamepads until you press a button. Press any button, then it appears. Also make sure no other app has exclusive control.
From the tool guide Ask a follow-upWhat is stick drift?
The stick reports movement at rest, so a character or camera creeps on its own. It is caused by dust, wear or a failing potentiometer.
From the tool guide Ask a follow-upHow much drift is normal?
Values within about ±0.05 of zero are normal. Larger resting values usually mean drift.
From the tool guide Ask a follow-upDoes it support PlayStation and Xbox controllers?
Yes — Xbox, DualShock 4, DualSense, Switch Pro and most generic pads using the standard mapping.
From the tool guide Ask a follow-upCan I test vibration?
Yes, in browsers that support it (Chrome and Edge). The button sends a short dual-motor rumble.
From the tool guide Ask a follow-upIs anything uploaded?
No. Input is read locally in your browser.
From the tool guide Ask a follow-upWhat this tool does
Plug in or pair a controller, press any button and this tester shows it instantly: every button lights up with its name, triggers show how far they are pressed, and both analogue sticks are drawn live with their exact axis values. It works with Xbox, PlayStation DualShock and DualSense, Nintendo Switch Pro and most generic USB or Bluetooth pads.
How to use it, step by step
- Connect your controller by USB or Bluetooth.
- Press any button so the browser reveals it.
- Press every button and move both sticks in full circles.
- Click Check stick drift with your hands off the controller.
Tips from the guide
- Pair the controller by cable first — Bluetooth adds delay and can drop inputs.
- Test with your thumbs off the sticks for the drift check.
- If the browser shows no controller, press a button and reconnect once.
- Some controllers have a mode switch (X / D / S) that changes how they appear.
Common mistakes to avoid
- Judging drift while a thumb rests on the stick.
- Assuming a controller is broken when it is in the wrong input mode.
- Testing through a wireless dongle that is far away.
Who uses it
- Gamers. Check a controller for drift or dead buttons before an important match.
- Buyers of used controllers. Verify every input works before you pay.
- Repair shops and streamers. Diagnose faults quickly on any platform.
How to ask a question people can answer
A good thread on the Gamepad & Controller Tester saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
