Web-Based Gamepad Tester for PS4, PS5, Xbox and More

Our web-based gamepad tester is an online browser tool that helps you check if your game controller is working properly. It reads controller inputs, tracks real-time commands, measures latency, and shows how joysticks and triggers respond without installing any software or drivers. Just plug in your PS5, Xbox, Nintendo Switch, or PC controller, open the tool, and start testing.

Gamers, developers, and streamers use this gamepad controller tester. Gamers check for stick drift, unresponsive triggers, or faulty buttons. Developers use it to validate input across platforms. Streamers rely on them to display live inputs during gameplay. If you're diagnosing problems or checking calibration, our browser-based tester saves time and avoids unnecessary replacements.

How Online Gamepad Testers Work in Your Browser

The Gamepad API is a built-in feature in modern browsers that allows users to detect and communicate with connected controllers. It supports DualSense, PS3, PS4, PS5, Xbox controllers, and various third-party USB gamepads. Once a controller is plugged in via Bluetooth or USB, the browser automatically begins polling the device for input signals.

Each control element, like buttons, analog sticks, and triggers, sends numeric values that indicate its current state. For instance, a fully pressed trigger typically reads as 1.0, while a centered joystick rests at 0.0. This data is captured through a process called input mapping, which identifies and labels each input based on the controller's specific structure.

Why Choose Our Web Gamepad Tool Over Software

Traditional controller testing tools often require software installation, which can create compatibility issues or slow down performance. Here is a comparison table of our tester vs software to understand the differences:-

What Is Stick Drift?

Stick drift is when your controller's joystick moves your character or camera without you touching it. It happens due to wear in sensors, dirt buildup, or hardware fatigue, and affects most modern controllers, including PS5, Xbox, and Nintendo Switch.

How to Check for Stick Drift (PS5, Xbox, PC)

Follow these steps to test if your controller has stick drift:

Connect Your Controller
Plug your controller into your PC or console using a USB cable or connect it via Bluetooth.

Open a Gamepad Tester
Launch our web-based gamepad tester in a supported browser like Chrome, Firefox, or Edge.

Don't Touch the Sticks
Let the controller sit still. Watch the on-screen tester carefully.

Look for Movement
If the joystick marker (dot or crosshair) moves without any input, your controller is drifting. Also, check the X and Y axis values. They should both stay at 0.00 when untouched.

Even Small Values Matter
Numbers like X: 0.03 or Y: -0.02 may seem minor but still indicate early sensor wear or internal issues.

Confirm It's Not a Port/Device Problem
Try the same controller on a different USB port or another device to rule out external causes.

How to fix stick drift in PS5.

To fix stick drift on a PS5 DualSense follow these steps:-

Clean around the analog stick with isopropyl alcohol and a cotton swab.
Recalibrate the controller via Settings ⇒ Accessories ⇒ Controllers.
If drift persists, replace the stick module—especially easy on the DualSense Edge, which supports swappable thumbsticks without soldering.

How to Fix Drift on Xbox Controllers

Start with the Xbox Accessories App to recalibrate sticks and adjust dead zones.
Minor unintended input from idle analog sticks can be masked by increasing the deadzone range.
Switch between wired and wireless modes to rule out Bluetooth interference.
For Xbox Elite Series 2, replace the thumbstick module if needed.
Standard Xbox controllers may require soldering.
Also, install the latest firmware updates to improve input accuracy and reduce lag.

How to Fix Drift on PS4/PS3

On PS4, use Steam Controller Settings to recalibrate input.
For Windows, update drivers through Device Manager.
PS3 controllers need tools like DS3 Tool or ScpToolkit to test and remap inputs.
If cleaning doesn't help, replace the internal stick module using a repair kit.
Be cautious—PS4 and PS3 internals are compact. If you're not confident, visit a controller repair specialist.

How to fix Faulty and sticky Buttons on a Gamepad

Sticky or non-working buttons are usually caused by dirt, worn pads, or minor hardware faults. Follow these steps to fix your gamapad buttons:-

Use a cotton swab with isopropyl alcohol to clean around the buttons. If your controller can be opened, gently clean the rubber pads and contacts inside.

If cleaning doesn't work, check for worn-out rubber domes. These can be replaced with affordable kits available online for PS5, Xbox, or other models.

Still no luck? The issue might be with the internal solder points. Loose or broken connections need re-soldering, which is best done by someone experienced, or take it to a repair shop.

Make sure your controller's firmware and drivers are up to date, as software bugs can sometimes cause input issues.

Once done, test everything using our Online gamepad tester. Press each button and confirm it responds instantly on-screen.
