Gamepad Tester: check your controller online

Gamepad Tester is a free online gamepad tester for checking how your controller responds before you launch a game. Connect a compatible controller, press a button, and watch its inputs appear in your browser. You can inspect buttons, analog sticks, triggers, and supported vibration motors from one page. Whether you are investigating an unexpected movement or checking a recently purchased controller, the live readings help you understand what your browser receives. There is no account to create and no tester software to install.

How to use the gamepad tester online

Connect your controller with a data-capable USB cable, or pair it through your computer's Bluetooth settings. Open the tester, keep this tab active, and press a controller button to allow the browser to detect it. Choose the matching Gamepad slot if more than one device is connected. Start in Overview to see the controller illustration, stick coordinates, trigger values, and button grid together. The demo lets you explore the interface with simulated inputs, but you must exit demo mode to test your actual hardware.

Press and release each button individually, including the directional pad, shoulder buttons, and stick clicks. A tested button stays marked so you can track your progress. Squeeze each trigger gradually and look for a smooth response on controllers with a standard mapping. Rotate both sticks slowly around their edges, then let them return to rest. If your controller uses a non-standard mapping, use the numbered buttons and Raw data view instead of assuming the illustration matches its physical layout.

Gamepad tester for PS5 and PS4 controllers

Looking for a PS5 gamepad tester? Connect your DualSense controller to your computer and check whether your browser exposes it through the Gamepad API. This gamepad tester for a PS5 controller shows the buttons and axes that the browser makes available. Check both sticks, the directional pad, shoulder buttons, and triggers. A USB connection is a useful starting point when Bluetooth detection is inconsistent. Browser access does not guarantee support for every DualSense feature: adaptive trigger effects and advanced console haptics are outside this tool's standard vibration test.

You can also use the gamepad tester for PS4 DualShock 4 controllers when your operating system and browser recognize them. The standard layout pairs Xbox and PlayStation labels, such as LB / L1 and RT / R2, to make comparisons easier. Some system buttons or touchpad functions may not appear as ordinary inputs. A missing browser input alone does not establish a hardware fault; check the mapping and compare with another compatible application before drawing a conclusion.

Xbox gamepad tester and Windows setup

Use the Xbox gamepad tester to inspect a recognized Xbox controller's face buttons, bumpers, triggers, and analog sticks. Try USB first for a straightforward connection, then repeat over Bluetooth if your model supports it. Comparing both connections can help narrow down a detection problem. When using this as a Windows gamepad tester, first confirm that Windows recognizes your controller. Then return to this page and press a button. If detection fails, check the cable, pairing status, and whether another controller application is changing the device mapping.

Gamepad tester stick drift checks

Stick drift is unwanted movement reported while an analog stick is untouched. Open Stick & drift, place the controller on a stable surface, and run the three-second resting measurement. The tool reports average and peak center offsets for each stick during that sample. Watch the live X and Y values as well: a consistent offset and a value that jitters around the center can look different. Repeat the measurement after moving and releasing the sticks to see whether the behavior is consistent.

There is no single offset percentage that proves every controller is faulty. Games apply different dead zones, and controller designs vary. Compare the readings with the behavior you notice in your game. The visual dead zone slider changes the plot guide only; it does not repair drift, recalibrate hardware, or change your game's settings. If you adjust a dead zone in a game or manufacturer utility, test again there to judge the effect on aiming and movement.

Run a gamepad tester vibration test

Open Vibration to try the strong motor, weak motor, or both together. A gamepad tester vibration test works only when the controller, connection, operating system, and browser expose a compatible vibration actuator. If the controls report that vibration is unavailable, try a USB connection and another compatible desktop browser. No vibration in this website does not automatically mean the motors are broken. Compare with a game that supports your controller's rumble before deciding whether the problem is hardware or browser support.

How this HTML5 gamepad tester works

This HTML5 gamepad tester uses the browser's Gamepad API to read available controller snapshots and display them as live values. People also call this an HTML gamepad tester because it runs on a web page without a separate testing app. Features depend on what the browser exposes, so a controller that works in a native game may behave differently here. Use the site over HTTPS and keep your browser updated. The displayed updates are browser samples; they do not measure exact hardware input latency or USB polling rate.

A gamepad tester website for repeatable checks

If you searched for a hardware tester gamepad tester, this tool focuses specifically on controller inputs visible to your browser. Use the same sequence each time: check every button, rotate the sticks, measure resting drift, and try supported rumble. Export a JSON report to keep the current readings and button coverage, or reset the session before another test. This gamepad tester site processes controller readings locally, and reports download to your device. Start your controller test or visit connection help for detection troubleshooting.
