What Does PS5 Controller Tester Check?
PS5 Controller Tester is a free browser-based tool that checks every input on your Sony DualSense controller in real time. It uses the browser Gamepad API to read button presses, analog stick movement, adaptive trigger pressure, and haptic feedback support without requiring any software download. The tool also runs a stick drift test by monitoring whether your thumbsticks stay off-center for more than two seconds without any intentional movement, helping you identify hardware issues quickly.
Supported Controllers
This tool is designed primarily for the PS5 DualSense controller connected via USB cable or Bluetooth wireless. It also works with the DualSense Edge and older DualShock 4 controllers on most browsers. Chrome and Edge offer the best compatibility with the Gamepad API, while Firefox also provides solid support. The tool works on Windows, macOS, and Linux desktops. Mobile browsers and Safari currently have limited or no gamepad support, so a desktop browser is recommended for accurate controller input testing.
How To Use This Tool
Plug your DualSense into your PC via USB or pair it over Bluetooth, then open this page in Chrome or Edge. Once connected, press any button on the controller to activate detection. The status badge at the top will switch to Connected. From there, press every button to confirm it registers, move both analog sticks to check axis response, and squeeze the L2 and R2 triggers gradually to see pressure values. Leave the sticks untouched for a few seconds to complete the thumbstick drift detection check.
Understanding Your Results
Every button should light up instantly when pressed with no delay. Analog stick values should return close to zero percent when released, and trigger pressure should scale smoothly from zero to one hundred. If a button fails to register, it may indicate a worn contact. Stick values that stay above five percent at rest for over two seconds will trigger a drift warning, which typically signals a worn-out potentiometer. Haptic feedback support depends on your browser, with Chrome currently offering the best DualSense vibration actuator detection.
Frequently Asked Questions
Q: Why is my PS5 controller not detected?
A: Make sure you are using Chrome or Edge on a desktop. Press any button after connecting via USB or Bluetooth to trigger gamepad detection in the browser.
Q: Can I test DualSense haptic feedback online?
A: This tool detects whether your browser supports the vibration actuator on the DualSense. Full haptic testing requires Chrome as Firefox does not yet support this feature.
Q: What causes PS5 stick drift?
A: Stick drift is usually caused by worn analog potentiometers inside the thumbstick module. It appears when the stick reports movement even while you are not touching it.
Q: Does this tool work without installing anything?
A: Yes, it runs entirely in your browser using the Gamepad API. No app, extension, or plugin is needed.
Q: Is the DualSense Edge supported?
A: Yes, the DualSense Edge works with this tool the same way as the standard PS5 controller. All buttons and sticks are detected through the standard Gamepad API mapping.
Q: Can I test my controller on a Mac?
A: Yes, Chrome on macOS supports the Gamepad API. Connect your DualSense via USB or Bluetooth and press a button to begin.
