Built different.
Not just another tester.
Other testers show you one number and stop. We cover the whole lifecycle: measure the fault, diagnose it, fix it, and train the skill it broke.

How do I run a controller test online?
To run a controller test online: connect your controller via USB or Bluetooth, open the test page on ControllerTesting.com, and interact with your controller. The browser reads input through the standard Gamepad API. No download, no account, and no software installation is required.
Can I test a PS5 DualSense or PS4 DualShock controller online?
Yes. Connect your PS5 DualSense or PS4 DualShock 4 controller by USB or Bluetooth, then open the PS5 controller test or general drift detector. The browser exposes controller input through the Gamepad API on Chrome, Edge, and Firefox.
What does the gamepad tester check?
The gamepad tester suite checks: analog stick drift (to 0.1% precision), all buttons, trigger pressure curves, vibration motors, polling rate in Hz, stick circularity, deadzone thresholds, and input latency. Start with the Full Diagnostic for a complete 2-minute checkup.
Is ControllerTesting.com free to use?
Yes. All 39 diagnostic tools on ControllerTesting.com are free to use. No account is required, no data leaves your device, and no software needs to be installed — everything runs in your browser using standard Web APIs.
How do I know if my controller has stick drift?
Connect your controller, open the Stick Drift Detector at controllertesting.com/test/controller/drift, and let the sticks rest at center. A reading above 2% on either axis indicates drift. Values under 2% are typically within the clean range. The test shows drift to 0.1% precision in real time.
Does the controller test work on Xbox controllers?
Yes. Xbox Series X, Xbox Series S, and Xbox One controllers work with the gamepad tester on Chrome, Edge, and Firefox via USB or the Xbox Wireless Adapter. Bluetooth Xbox controllers also work on most modern browsers.
Your controller deserves a real diagnosis.
Takes 2 minutes. No downloads, no accounts, no data collection. Everything runs in your browser.
The Complete Browser-Based Controller Diagnostic Platform
Whether you're a competitive esports player looking to eliminate input delay on controller games, or a casual gamer verifying a secondhand console to play the best nintendo switch games, hardware reliability is critical. From preparing for upcoming nintendo switch 2 games on the much-anticipated nintendo switch 2 console to enjoying classics on a nintendo switch oled or nintendo switch lite, having a fully functional gamepad is non-negotiable. Our platform provides an instant, installation-free controller test directly in your browser. Utilizing the HTML5 Gamepad API, we read raw telemetry from your hardware, allowing you to visualize analog stick accuracy, button actuation, and trigger linearity across all major devices—including the playstation 5 controller, the nintendo switch pro controller, and the xbox elite controller series 2.
Precision Diagnostics: Visualizing Stick Drift and Wear
Analog stick degradation is the most common point of hardware failure in modern gamepads. Before you invest in a costly nintendo switch joy con repair or buy a new set of nintendo switch games, it is crucial to determine if your crosshair movement is caused by a software deadzone configuration or physical potentiometer wear. Our diagnostic suite measures resting axis variance down to a 0.1% margin of error. If you are experiencing unexpected camera movement on your DualSense, running our dedicated test will quickly confirm the presence of ps5 controller drift, empowering you to adjust your in-game settings or pursue a warranty claim.
Supported Hardware: From Next-Gen to Retro
Our testing engine is built for maximum compatibility. You can perform a rigorous xbox controller test to verify the adjustable tension thumbsticks on an xbox elite controller (including the xbox elite controller series models), or map the unique inputs of a switch 2 pro controller. We extensively support nintendo hardware; whether you are testing a standard nintendo switch joy con or mapping a legacy super nintendo controller switch setup via USB, our interface accurately reflects the nintendo controller layout. Even an old nintendo controller or an original nintendo controller paired with an adapter can be analyzed for input latency and ghosting. If you need to test a joy con controller, a switch controller, or verify nintendo switch controller drift, we have you covered.
Connectivity: Pairing Your Device
A frequent barrier to hardware testing and playing controller games for pc is establishing a stable connection. A common question we receive is how to connect ps5 controller to pc, how to connect ps5 controller generally, or how to connect ps5 controller to iphone. For PC, the most reliable method with the lowest latency is a direct USB-C connection. For wireless testing or iOS gaming, simply hold the Create and PS buttons simultaneously until the light bar flashes to initiate Bluetooth pairing. Once connected, your OS will expose the device to the browser, allowing you to instantly play online controller games (or pc controller games) or run our polling rate diagnostic on your ps5 controller pro or standard ps5 controller. We also fully support the xbox controller and ps4 controller for all these features.
Limitations and Browser Implementation
While our ps4 controller test and ps5 controller test suites are highly accurate, it's important to understand the limitations of the Gamepad API. Browsers normalize inputs differently depending on your operating system. For example, Windows may apply a hardware-level deadzone to Xbox controllers before the data ever reaches the browser. Similarly, testing a nintendo controller switch setup, a joy con 2, or a switch joy con wirelessly via Bluetooth can introduce artificial latency compared to a wired connection. We always recommend using a wired connection on a Chromium browser (like Google Chrome or Microsoft Edge) for the most accurate diagnostic results across all your nintendo switch and next-gen gaming hardware.
