Nintendo Joy-Con Controller Test
Check Nintendo Joy-Con stick and button input online. Test each connected device and understand pairing and browser limitations.
Local-only test
Connect with USB, Bluetooth, or a supported wireless adapter. Then press any controller button so your browser can expose it. Your readings are processed on this device.

Axes and mapping
Use these values to spot unusual layouts. A blank standard mapping does not automatically mean the controller is defective.

Reports are stored in this browser. Sharing is optional and puts only the selected result in the link.
Diagnostic readings describe what this browser receives, not electrical measurements from the controller. Confirm important findings in the game or device where you plan to use the controller.
What this browser check can reveal
Joy-Con controllers may appear to a computer as separate left and right gamepads instead of one combined controller. Select each detected device in the tester and check its analog stick, directional or face buttons, shoulder controls, and connection stability.
A browser cannot combine separate Joy-Con devices into a single virtual controller. Pairing behavior, SL/SR buttons, motion sensors, HD Rumble, rail connection, and system buttons depend heavily on operating-system and driver support.
For drift testing, place the selected Joy-Con on a flat surface and sample it without touching the stick. Save a separate report for the left and right device so the results remain clear.
Start with a known, stable connection.
- ✓Select and test each browser-detected Joy-Con separately
- ✓Measure small-stick center offset and range
- ✓Verify exposed face, direction, and shoulder buttons
- ✓Save clearly labeled left and right reports
A practical controller checklist.
- 01
Confirm the controller appears and the reported name or identifier is plausible.
- 02
Press and release every button, D-pad direction, stick click, bumper, and trigger.
- 03
Run the hands-off drift sample, then sweep both sticks through their full range.
- 04
Disconnect and repeat in the connection mode you actually plan to use.
- 05
Verify any fault inside a supported game or console before making a purchase or repair decision.
Compatibility is a chain, not a promise

Nintendo Joy-Con Controller Test questions
Can I test both Joy-Con as one controller?
Only if your operating system or a trusted compatibility layer already presents them as one gamepad. The webpage itself cannot merge two physical devices.
Why are my Joy-Con shown separately?
That is a common computer Bluetooth behavior because each Joy-Con is an independent wireless device. Nintendo Switch pairing handles combination at the system level.
Does the test check Joy-Con motion controls?
No. The browser Gamepad API generally exposes standard buttons and axes, not the complete motion-sensor or rail-feature set.
