Nintendo Switch Pro Controller

Detect exact analog stick metrics and polling rate for competitive Smash Bros matches.

Nintendo Joy-Con Controllers (Left & Right)

Both Joy-Cons can be tested independently via a Bluetooth connection to your PC or mobile device.

Nintendo Switch Lite Controls

Run the local browser tester directly on your Nintendo Switch to verify the built-in control pads.

Third-Party Nintendo Switch Controllers

Supports 8BitDo, PowerA, Hori, and PDP variants utilizing native Bluetooth or USB mappings.

Hold the small sync button on your Joy-Con or Pro Controller to enter Bluetooth pairing mode. Connect it to your PC, Mac, or phone. After connecting, return to this tab and press any button. The visual engine will immediately connect to your device.

Joy-Con Drift Test

The infamous Joy-Con drift occurs when dust or wear ruins the thumbstick sensor. Use the left/right stick precision analytics to monitor idle movement.

Button Response Test

Ensure the shoulder buttons (L/R) and triggers (ZL/ZR) register immediately without needing excessive force.

Analog Stick Accuracy Test

Rotate the thumbsticks along the circular boundary. An average circular error above 10-15% indicates significant hardware degradation.

Connection Problems

If your inputs are lagging or dropping, the "Signal Jitter" tool on the right will isolate your Bluetooth interference.

Calibration Issues

Verify whether the hardware needs factory recalibration through the Switch console menus or if it is purely mechanical failure.

This page serves as the ultimate diagnostic Joy-Con Drift Tester. By analyzing raw input axis data (X and Y coordinates) down to the decimal, you can undeniably prove whether your Joy-Cons are malfunctioning before submitting them for warranty repair.

Our layout mapping correctly mirrors the Nintendo format: X (Top), A (Right), B (Bottom), Y (Left), eliminating the confusion common with generic controller testers.

Stress-test the rotational range of your analog modules. Discover mechanical blind spots seamlessly.

Nintendo Switch triggers (unlike PlayStation or Xbox) are digital clicks. Our tool registers these instantaneous clicks perfectly via the LB/RB and LT/RT visualizer mappings.

Tested and fully optimized for Google Chrome, Brave, Microsoft Edge, and Safari using the w3c Gamepad API.

Works flawlessly on Windows 10/11 laptops, macOS desktops, iOS devices, Android smartphones, and directly within the Nintendo Switch's hidden browser app.

How do I test my Nintendo Switch Pro controller?

Use a USB-C wire to plug it into your computer, or pair it via your computer's Bluetooth settings (hold the sync button by the USB port on the controller).

How do I test Joy-Con on PC?

Joy-Cons represent two separate Bluetooth devices. You can connect them to Windows or Mac individually via Bluetooth Settings to test them independently.

Can this detect Joy-Con drift?

Yes. If the blue testing dot veers off the perfect idle crosshair (0.0000 X/Y), your controller is exhibiting unmistakable stick drift.

Does this tester work with Bluetooth?

Yes, any Bluetooth-connected Nintendo gamepad emitting standard HID events will be natively recognized without extra configurations.

Do I need special software?

No. Do not install unsafe drivers or mapping software (like BetterJoy or DS4Windows) before running this raw hardware diagnostic test.

• Xbox Controller Tester
• PlayStation Controller Tester
• Mouse Click Tester
• MacBook Keyboard Test
• Monitor / Dead Pixel Test
• Generic Gamepad Tester

This tool utilizes HTML5 requestAnimationFrame combined with the standard navigator.getGamepads() API, guaranteeing sub-millisecond data polling relative to your monitor's refresh rate.

If your controller is missing inputs, try a hard reset (hold the power button), unpair the Bluetooth device entirely from your PC/Console, ensure its battery is adequately charged, and reconnect.
