Gamepad Tester & Debugger - Live Controller Diagnostics in Your Browser
Live via HTML5 Gamepad API
Using the HTML5 Gamepad API, it pulls live data from your inputs the moment you connect, giving you real feedback on every press, every axis shift, and every rumble.
All Supported Devices
Whether you're working with PS5 DualSense or DualSense Edge controllers, a PS4 DualShock controller, PS3 gear, Xbox One, Xbox Series, or even generic PC gamepads and experimental hardware like modded joycons, this tester handles them all across all supported devices.
Deep Test Suite
Run a button test to catch any weak button response, or fire up the joystick tester to map out joystick accuracy and expose stick drift before it costs you a match. The analog sticks are put through circularity tests to check how cleanly they trace a full circle , something most tools never bother with.
Microphone & Vibration
You can also run a controller vibration tester to judge vibration controls and motor strength, and even a microphone test for supported headset-enabled controllers.
Analog Calibration
For anyone serious about precision, the built-in analog calibration system lets you view and fine-tune dead zones, adjusting thresholds and improving overall accuracy without touching a single system setting.
Raw Numbers That Matter
This online gamepad tester surfaces those numbers , axis offsets, dead zones, vibration response curves , so you can make informed decisions about calibration, repairs, or replacements. From PS3 legacy gear to cutting-edge Xbox Series controllers, every input is captured and displayed with the kind of live precision that turns guesswork into a clear answer.
Stick Drift Fix - Diagnose Your Joystick with a Live Drift Tester
The moment your gamepad starts moves on its own, the first real step is to locate the source , and that's where our online gamepad tester comes in. Using the drift tester, you can verify joystick drift in seconds and identify whether the problem sits in the hardware or software.
- 1🔍Start by checking if a firmware or drivers update resolves the issue.
- 2⚙️Use the built-in calibration tools to calibrate your controller and adjust sensitivity.
- 3🧴If drift persists, clean the joystick carefully with isopropyl alcohol to clear debris affecting the contacts.
- 4🔧Should that fail, the next step is to replace the joystick modules entirely.
- 5🔘Run a controller button test to catch any faulty buttons, stuck buttons, or unresponsive inputs.
- 6🔌Check the button contacts and worn-out rubber pads, re-solder any damaged connections, replace degraded parts.
- 7💾Update your controller drivers.
- 8✅Retest everything using the controller tester to confirm all button issues are resolved before you call it done.

Button, Stick & Vibration - Full Controller Test in One Session
Button Response
During any controller test session, this Gamepad Tester lights up every face, shoulder, and trigger input the moment it registers, letting you confirm pressure, travel, and simultaneous presses with the kind of button response clarity that matters most on PC gaming controllers.
Stick Heatmaps & Deadzone Scan
Spin both thumb-sticks through their full range and the tool instantly plots heatmaps that reveal stick drift, drift amplitude, and deadzone thresholds in a single deadzone scan , something I've found cuts controller tester diagnostic time in half.
Vibration Motor Test
Activate a single burst or continuous rumble through the vibration controller test to check motor strength by feel, giving you a complete picture of how your controller performs across every layer of the test.

How to Use the Gamepad Tester - Connect, Test & Verify in Minutes
Connect Your Controller
Connect your controller via USB-C, Micro-USB, or Bluetooth pairing, then let the Gamepad API guide the rest , press any button and the Gamepad Tester updates the icon instantly, so if nothing changes, that switch is likely faulty.
Rotate the Joystick
Rotate the joystick and the Gamepad Tester traces a live path of every movement, letting you verify full range and smoothness without any guesswork — something I always do first when diagnosing a controller that feels slightly off.
Run the Vibration Test
Click the vibration test button, select infinite vibration, and the Gamepad Tester engages the motors so you can feel their operation immediately and confirm everything is working as it should.
Quick Fixes When Your Controller Won't Show Up
Close Exclusive-Mode Apps
If Gamepad Tester fails to detect your pad on Windows, close any exclusive-mode apps like Steam Big Picture that may be blocking access , this is the first thing I check and it resolves the issue more often than you'd expect.
Use Chrome or Firefox
On macOS, stick to Chrome or Firefox since Safari only exposes partial Gamepad API events, limiting what the tool can read from your controller.
Vibration Not Triggering
If vibration fails to trigger, make sure your browser tab is focused and that your system accessibility settings allow haptic feedback , a small tweak that's easy to miss but essential for the Gamepad API to deliver full results.
