Gamepad Tester – Pro Diagnostic Tool

Free Online Gamepad Tester – Diagnosing PS5, Xbox & Switch Controllers

Welcome to the industry-standard free online gamepad tester. Whether you are a competitive FPS player checking for input lag or a casual gamer diagnosing a broken button, our tool provides a complete laboratory-grade analysis of your hardware. We support every major console, including the PS5 DualSense, Xbox Series X, and Nintendo Switch JoyCons, all directly in your browser with no download required.

Why You Need a Professional Controller Tester

Standard testing tools often miss critical hardware faults. Our online gamepad tester visualizes hidden data streams that the console itself won't show you. By running a controller button test here, you can identify issues like "Ghost Inputs," "Double Clicking," or "Sticky Triggers" before they ruin your ranked match.

Furthermore, we are one of the only tools that actively measures Polling Rate (Hz) in real-time. If you are playing on PC, ensuring your controller runs at 1000Hz (1ms delay) versus the standard 125Hz (8ms delay) gives you a mathematical advantage in fast-paced games like Call of Duty, Fortnite, and Valorant.

Complete Diagnostic Features

• Stick Drift Test & Visualization: Drift is the #1 killer of controllers. Our stick drift tester maps your analog stick's resting position to 5 decimal places. If your stick is "moving" (values fluctuating) while you aren't touching it, our tool will flag it immediately as hardware drift.
• Circularity Error Test: Pro gamers need precision. This test measures how perfectly circular your analog stick rotation is. Official DualSense Edge and Xbox Elite Series 2 controllers typically have an error rate under 10%, while generic pads may show 15-20%.
• Vibration & Rumble Motor Test: Check if your haptic feedback motors are dying. We allow you to test the "Heavy" (Left) and "Light" (Right) rumble motors independently using the browser's vibration API.
• Trigger Sensitivity Analysis: For racing game fans, we visualize the analog pressure of your L2/R2 triggers to ensure they reach 100% acceleration without needing to be pressed through the floor.

Troubleshooting: How to Fix Common Issues

1. Fixing Stick Drift (The "Ghost Movement")

If our Stick Drift Tester confirms drift, it means your potentiometer sensor is dirty or worn.
The Fix: Start by cleaning the joystick base with compressed air and isopropyl alcohol (90%). If the hardware is permanently damaged, use our Deadzone Calculator to create a software "mask" that hides the drift in-game.

2. Fixing Unresponsive Buttons

If a specific button (like 'A' or 'X') flickers during the controller button test, the conductive rubber pad underneath is likely worn out.
The Fix: You can open the controller and clean button contacts with alcohol. If the rubber is torn, you will need to buy a cheap replacement pad online.

3. Controller Not Connecting?

If you see "No Controller Detected," try these steps:

• Press any button to "wake up" the controller.
• If using Bluetooth, try connecting via USB-C cable.
• Ensure you are using a modern browser like Google Chrome or Microsoft Edge (Firefox has limited gamepad support).
• Update your controller firmware or PC drivers.

How to Test Microphone?

While this tool focuses on input testing, some controllers like the DualSense have built-in mics. You can usually test the microphone test functionality in your Windows Sound Settings, as browsers segregate audio input from gamepad input for privacy.
