Why it's better
Why this gamepad tester is better
Most controller testers only show raw numbers. This one gives you a clear picture of your controller plus the checks that actually matter: drift, range and rumble.
Stick drift detection
Let go of the sticks and the tester measures where they rest, flagging drift beyond your chosen deadzone.
Circularity test
Rotate a stick around its edge to map its full range and get a circularity error score for each stick.
Vibration test
Test the strong and weak motors separately or together, set intensity and length, and try trigger rumble where supported.
Raw values and press counts
See the exact value of every button and axis, plus how many times each button has been pressed, to catch sticky or double-registering buttons.
Any controller, up to four
Xbox, PlayStation, Switch Pro, 8BitDo and generic gamepads, with matching button labels and up to four controllers at once.

How to use
How to test a controller online
A complete controller check takes about a minute.
Testing the rest of your setup? Try the keyboard tester, the mouse tester or the speaker test for your headset.
Connect and press a button
Plug in your controller or pair it by Bluetooth, then press any button so the browser can detect it.
Press every button
Each button should light up once per press. Check the press counter for buttons that don't register or register twice.
Check the triggers
Squeeze each trigger slowly. The bar should fill smoothly from 0 to 1 without jumps.
Test the sticks
Rotate each stick slowly around its edge, then let go. Look at the circularity score and the resting position for drift.
Test vibration
Press Rumble, then try each motor on its own. You should feel a strong, low buzz and a lighter, higher buzz.
Troubleshooting
Fixing common controller problems
Most issues can be fixed at home without replacing the controller.
Controller not detected
Press a button while this page is open, since browsers hide controllers until then. Try a data-capable USB cable, re-pair Bluetooth, close other apps using the controller, and use Chrome, Edge or Firefox.
Stick drift
Blow compressed air around the stick base and rotate it firmly several times. Recalibrate in Windows (search for Set up USB game controllers) or Steam, and raise the in-game deadzone slightly.
Buttons not registering
Watch the raw list while pressing. If a button never lights up or counts twice, clean around it and update the controller firmware through its official app.
No vibration
Browser rumble support varies. Use Chrome or Edge, connect by USB, and make sure vibration isn't turned off in the controller or system settings.
Button mapping
Standard gamepad button mapping
Browsers number buttons in a standard order. Here's how the numbers match each controller's labels.
| Index | Xbox | PlayStation | Nintendo Switch Pro |
|---|---|---|---|
| 0 | A | Cross | B |
| 1 | B | Circle | A |
| 2 | X | Square | Y |
| 3 | Y | Triangle | X |
| 4 / 5 | LB / RB | L1 / R1 | L / R |
| 6 / 7 | LT / RT | L2 / R2 | ZL / ZR |
| 8 / 9 | View / Menu | Create / Options | Minus / Plus |
| 10 / 11 | Left / right stick click | L3 / R3 | Left / right stick click |
| 12 to 15 | D-pad up, down, left, right | D-pad up, down, left, right | D-pad up, down, left, right |
| 16 | Xbox button | PS button | Home |
| 17 | Not used | Touchpad click | Capture (some browsers) |
FAQ
Gamepad tester FAQ
How do I test my controller online?
Connect it by USB or Bluetooth, open this page and press any button. Every button, trigger and stick then lights up on screen as you use it.
Why isn't my controller detected?
Browsers only show a controller after you press a button while the page is open. If it still doesn't appear, reconnect it, try a USB cable, and use Chrome, Edge or Firefox.
How do I check for stick drift?
Let go of both sticks and watch the readings. A healthy stick rests close to 0.00; if it stays above your deadzone, usually about 0.1, or moves on its own, the stick is drifting.
What is a good circularity error?
Rotate each stick slowly around its edge. Most controllers score under about 10%. Much higher values mean the stick doesn't reach its full range in some directions.
Does the vibration test work in every browser?
Vibration works in Chrome and Edge with most Xbox and PlayStation controllers. Firefox and Safari have limited or no support for controller vibration.
Does it work with PS5, PS4, Xbox and Switch controllers?
Yes. Any controller your browser recognises works, including DualSense, DualShock 4, Xbox Series and Xbox One, Switch Pro, 8BitDo and generic USB gamepads.
Can I test more than one controller at once?
Yes. Connect up to four controllers and switch between them with the tabs at the top of the tester.
What does standard mapping mean?
It means your browser recognises the controller layout and maps its buttons to a common order. Controllers without it still work, but buttons may appear in a different order.
Is anything installed or uploaded?
No. The test uses your browser's built-in Gamepad API and nothing leaves your device.
