Gamepad Tester

To test your gamepad, connect it to your computer via USB or Bluetooth, then open this page in Chrome, Edge, or Firefox. Press any button on your controller — the browser will detect it via the Gamepad API and our tool will display a visual controller layout with real-time button highlighting, analog stick positions, and trigger levels. You can test every button, both analog sticks, the triggers, and vibration. The tool works with Xbox, PlayStation, Switch Pro, and generic USB controllers.

Yes. If your controller supports vibration and your browser supports the Gamepad Vibration API, you can test the weak motor, strong motor, or both motors simultaneously using our vibration test section. Click "Weak Motor" for a gentle buzz (high-frequency rumble), "Strong Motor" for a heavy rumble (low-frequency), or "Both Motors" for the full dual-rumble effect. Note that not all browsers support the vibration API — Chrome and Edge have the best support. If your controller does not support vibration, the test buttons will be disabled.

The deadzone is a small area around the center of the analog stick where input is ignored. Without a deadzone, even tiny analog fluctuations would register as movement. Our tool displays a deadzone circle on each stick visualization — any movement within this circle is treated as "centered." If your drift extends beyond the deadzone, it will register as unwanted input in games. Understanding the deadzone helps you distinguish between normal analog noise and actual stick drift that affects gameplay.

Stick drift occurs when your analog sticks register movement even when you are not touching them. To test for stick drift, let go of both analog sticks and watch the stick visualizations in our tool. If the dot in the center moves away from the dead center position on its own, your controller has stick drift. The tool shows precise X/Y axis values so you can measure the severity. The deadzone is a small area around the center where input is ignored — if your drift extends beyond the deadzone, it will register as unwanted input in games. Stick drift is caused by wear in the potentiometer and is common in older PlayStation and Xbox controllers.

If your controller is not detected, try these steps: (1) Make sure the controller is connected via USB or Bluetooth before opening this page. (2) Press any button on the controller — the Gamepad API only activates after a button press for security reasons. (3) Try a different USB cable — some cables are power-only and do not transmit data. (4) Check if the controller is recognized by your operating system (e.g., Windows Game Controllers settings, macOS Bluetooth settings). (5) Try a different browser — Chrome and Edge have the best Gamepad API support. (6) If using Bluetooth, try disconnecting and reconnecting the controller.

If buttons register multiple presses on a single press, the button microswitch may be worn out (similar to mouse double-clicking). This is a hardware issue that worsens over time. If buttons don't register at all, the switch may be dead, or the button mapping may not be recognized by the browser. Try testing in a different browser to rule out software issues. Some controllers have non-standard button mappings that certain browsers may not recognize. If the issue persists across browsers, the button switch likely needs physical repair or replacement.

Input lag can be caused by: (1) Bluetooth interference — wireless connections add variable latency; try a wired USB connection for the lowest latency. (2) Low polling rate — some controllers poll at 125Hz (8ms) while others poll at 250Hz+ (4ms or less). (3) Browser extensions or high CPU usage slowing down event processing. (4) The controller's firmware may need updating. Our tool provides an estimated latency measurement by tracking the interval between input events and displays the estimated polling rate (Hz). For competitive gaming, use a wired connection and ensure your controller firmware is up to date.

No. This tool only verifies whether controller inputs reach the browser — it cannot determine the physical cause of a failure. If a button doesn't register or a stick drifts, the problem could be a worn potentiometer, a broken microswitch, a damaged ribbon cable, or a firmware issue, but our tool cannot tell you which one. What it can do is confirm which buttons are failing, how severe the stick drift is, and whether vibration motors are working, helping you isolate the problem. For physical damage diagnosis, consult the manufacturer.

No. This is a diagnostic tool, not a repair tool. It cannot clean potentiometers, replace analog stick modules, fix microswitches, or recalibrate hardware. What it can do is help you identify whether stick drift exists, how severe it is, and which buttons are affected. To fix stick drift, you can try: (1) cleaning the stick mechanism with contact cleaner, (2) recalibrating in the controller's software (if supported), (3) replacing the analog stick module (requires soldering), or (4) contacting the manufacturer for warranty service.

No. This tool cannot install, update, or flash controller firmware. Firmware updates must be done through the manufacturer's official software: Xbox Accessories app (Xbox controllers), PlayStation firmware update tool (DualSense/DualShock 4), or Steam (for some controllers). Driver issues are handled by your operating system. Our tool can help you verify whether a firmware update fixed an issue by retesting the controller after the update, but it cannot perform the update itself.

Our gamepad tester supports any controller that is recognized by the browser's Gamepad API. This includes: Xbox One and Xbox Series controllers, PlayStation 4 (DualShock 4) and PlayStation 5 (DualSense) controllers, Nintendo Switch Pro Controller, generic USB gamepads, arcade sticks, and retro controller adapters. Both wired USB and Bluetooth connections are supported. The standard button mapping (16 buttons + 4 axes) covers most modern controllers. Some controllers may have additional buttons or axes beyond the standard layout.

Yes. Xbox controllers (Xbox One, Xbox Series X/S, Xbox Elite) and PlayStation controllers (DualShock 4 for PS4, DualSense for PS5) are fully supported and are the most commonly tested controllers. Both work via USB wired connection and Bluetooth. Xbox controllers work natively on Windows and connect via Bluetooth on macOS. DualSense and DualShock 4 work via Bluetooth on macOS and Windows. All standard buttons, analog sticks, triggers, and vibration motors are detected. Press any button after connecting to start the test.

Yes. Bluetooth controllers work with this tool as long as they are paired with your computer and recognized by the operating system. The browser receives gamepad events regardless of the connection type. Note that Bluetooth adds some latency compared to wired USB connections — you can see this in the estimated latency and polling rate display. If you experience input lag or disconnections over Bluetooth, try moving closer to the computer, removing interference from other Bluetooth devices, or switching to a wired USB connection.

Yes. The Gamepad API supports up to 4 controllers simultaneously. If you have multiple controllers connected, a dropdown selector will appear in the tool header, allowing you to switch between them. Each controller is identified by its index (0-3). This is useful for testing multiple controllers before a gaming session or for comparing different controller models side by side.

Yes, our gamepad tester works on all operating systems — Windows, macOS, Linux, and ChromeOS — as long as you use a modern web browser (Chrome, Edge, Firefox, Safari, Opera). The test uses the standard Gamepad Web API, which is universally supported. Note that some controllers may require additional drivers on certain operating systems. For the best experience, use Chrome or Edge, as they have the most complete Gamepad API implementation including vibration support. Safari has limited Gamepad API support on some platforms.

Input latency (input lag) is the delay between pressing a button and the action registering in the game. Our tool provides an estimated latency measurement by tracking the interval between input events. While browser-based latency testing is not as precise as specialized hardware tools, it can help you compare different controllers or identify abnormally high latency caused by Bluetooth interference or low polling rate. For the most accurate results, use a wired USB connection, as Bluetooth adds variable latency. The estimated polling rate (Hz) is also displayed — higher polling rates (250Hz+) mean lower and more consistent latency.

No. This gamepad tester is 100% privacy-friendly. All testing happens locally in your browser using the standard Gamepad API. No button inputs, analog stick values, controller identification, or any other data are sent to any server. The controller state is read directly from the browser's gamepad polling loop and displayed on screen — nothing is logged, stored, or transmitted. You can verify this by checking your browser's network tab during testing.
