    Troubleshooting: not detected?

    1. Press any face button (A / ✕) to wake the pad. Browsers hide gamepads until first input.
    2. Prefer USB: some cables are charge-only. Try another cable or Bluetooth pairing.
    3. Use Chrome or Edge on desktop. Close Steam / DS4Windows overlays that capture the pad.

    How it works

    Three steps to a full health check

    1. 01

      Connect controller

      Plug in via USB (recommended) or pair over Bluetooth. Press any button to wake the pad. Browsers need this first input.

    2. 02

      Press every button

      Work through ABXY, bumpers, triggers, D-pad and stick clicks. Each press lights up on the visualizer and logs to history.

    3. 03

      Check sticks & rumble

      Rotate sticks fully to measure circularity, leave them centered to catch drift, then fire the vibration motors and calculate your health score.

    Glossary

    Controller terms, explained

    Stick drift

    Phantom movement signals at rest, usually from potentiometer wear or dust. Rest values above ±0.12 confirm hardware drift.

    Deadzone

    Center area ignored as input. A small software deadzone masks minor drift without hiding real faults.

    Polling rate

    How often the pad reports input. Bluetooth is typically 125 to 250 Hz; wired can reach 500 to 1000 Hz.

    Circularity error

    How perfectly circular full stick rotation is. Under 10% is excellent; over 25% means a worn module.

    Guide

    Gamepad tester online: the complete guide

    An online gamepad tester is the fastest way to answer one question: is my controller healthy? This free gamepad tester website reads your pad directly in the browser and visualizes every input in real time. Buttons light up as you press them, sticks trace their exact position, triggers show live pressure, and rumble motors fire on command. There is nothing to install, no account to create, and no waiting. If you just unboxed a controller, bought one used, or suspect yours is failing, this page gives you proof in under a minute.

    How this HTML5 gamepad tester works

    This site is an HTML5 gamepad tester, which means it uses the standard browser Gamepad API built into Chrome, Edge, and other modern browsers. When you press a button, the browser wakes the controller and exposes its state: 17 standard buttons plus extras, four stick axes, analog trigger values, and rumble actuators. Our game controller tester polls that state every animation frame and turns raw numbers into verdicts you can act on. Think of it as a hardware tester and gamepad tester combined with a debugger: the visualizer shows what your games see, the raw data grid shows exact values for fault finding, and the input history logs every press and release so double clicks, stuck buttons, and dead inputs cannot hide.

    How to test your controller in 30 seconds

    Using this controller tester online takes three moves. First, connect your pad with a USB cable, which is the most reliable option for any USB controller tester session, or pair it over Bluetooth. Second, press any button. Browsers hide gamepads until the first input, so that single press is what makes your controller appear on screen. Third, work through the checks: press every button once, pull both triggers slowly from rest to full pull, rotate each stick in a full slow circle, leave the sticks centered to catch drift, and fire the rumble motors. An online controller tester that runs entirely in the page means each result appears the instant you perform the input.

    Supported controllers: PS5, PS4, PS3, Xbox, Switch and PC

    As a PS5 controller tester, this page fully supports the DualSense and DualSense Edge, including touchpad clicks, Create and Options buttons, and trigger travel measurement. It works equally well as a PS4 controller tester for the DualShock 4 and as a PS3 controller tester for older Sixaxis and DualShock 3 pads connected over USB. On the Microsoft side, this Xbox controller tester covers Xbox One, Xbox Series X and S, Xbox Elite, and Xbox 360 controllers, with correct asymmetric stick layout and impulse trigger pressure display. That makes it a dependable Xbox controller tester online for both current and legacy pads. Nintendo players get a proper Switch Pro layout with minus, plus, Home and Capture buttons, and paired Joy-Cons appear as a testable pad in most desktop browsers. Because it reads the standard mapping, it also serves as a PC controller tester and PlayStation controller tester for generic XInput and DirectInput pads, fight sticks, and third party controllers. If your system sees the pad, this gamepad tester site can test it.

    Gamepad tester stick drift check

    Stick drift is the most common reason people open a gamepad tester stick drift check: the character walks or the camera creeps with thumbs off the sticks. Our tester samples each stick at rest and reports the offset to three decimals. Under ±0.05 is healthy, ±0.05 to 0.12 is minor offset you can mask with a small deadzone, and anything above ±0.12 is hardware drift that cleaning or a module replacement must fix. Pair the reading with the deadzone finder, which recommends the exact deadzone value to copy into your game, and thestick precision test, which maps full stick travel to expose worn modules that rest readings alone can miss.

    Gamepad tester vibration and trigger checks

    The built-in gamepad tester vibration check fires heavy and light rumble motors independently, plus burst and pulse patterns that expose sticking motors. Hold the pad while testing: a healthy motor hums cleanly, while grinding or silence on one side means failure. As a controller tester with vibration testing over a wired connection, it avoids the classic trap where Bluetooth drivers disable rumble and healthy motors look dead. For triggers, open the dedicatedtrigger travel test to verify smooth 0 to 100 analog travel, max reach at full pull, and left to right symmetry. And when input speed is the question, the reaction time test measures your pad with best of 5 scoring, which is the fairest way to compare wired against Bluetooth.

    Why test wired over USB first

    Every hardware gamepad tester gives the cleanest results over a wired USB connection. Bluetooth adds polling delay and jitter, can hide analog trigger pressure, and on Windows often disables Xbox rumble entirely. That is why each test on this gamepad tester website recommends USB with Chrome or Edge on desktop: it removes the connection as a variable, so any fault you see is genuinely the controller. Once a pad passes wired, repeating the same motions on Bluetooth tells you exactly what wireless costs on your setup. For buyers, sellers, and repair shops, the health score export turns those findings into shareable JSON proof.

    Is this controller tester safe and private

    Yes. A proper HTML gamepad tester never needs your data to leave the device, and this one does not. All polling, drift math, circularity analysis, and exports run locally in your browser tab. Pressing Start testing creates no account, sets no tracking beyond standard privacy friendly operation, and downloads nothing unless you explicitly export a JSON report. Whether you need an Xbox gamepad tester, a gamepad tester for PS5 controllers, or a general PC controller tester, you get the same guarantee: your inputs are read, visualized, and forgotten the moment you close the tab.

    FAQ

    Frequently asked questions

    How do I use the gamepad tester?

    Connect your controller with USB or Bluetooth, then press any button so the browser detects it. Work through every button, pull both triggers slowly, rotate each stick in a full circle, and fire the rumble motors. Use Chrome or Edge on desktop for the most complete results.

    What does a gamepad tester do?

    A gamepad tester reads your controller through the browser Gamepad API and shows every input live. It reports button presses, stick position and drift, trigger pressure, polling speed, and rumble output, so you can see exactly what your games receive.

    What does a controller tester do?

    A controller tester verifies that every input on your pad works correctly. It catches dead buttons, double clicking switches, drifting sticks, weak triggers, and silent rumble motors before they ruin a gaming session.

    Is a gamepad tester safe?

    Yes. This gamepad tester runs entirely in your browser tab. No controller data is uploaded, stored, or shared. Everything is forgotten when you close the page.

    How do I test my game controller?

    Plug it in over USB, open this page in Chrome or Edge, and press any button to connect. Test each input once, check sticks at rest for drift, confirm triggers reach 100 percent, and run the vibration check while holding the pad.

    Are controller testers necessary?

    They are not required, but they save money and arguments. Test before buying used, before a warranty claim expires, or after a repair. A two minute check beats guessing whether the pad or the game is at fault.

    Is the gamepad tester free?

    Yes, completely free with no account and no download. Every tool on this site, including the trigger, deadzone, precision, and reaction tests, is free to use as often as you like.

    Which controller tester is the best?

    The best controller tester is free, private, and needs no download. Look for live visualization, drift numbers, trigger and rumble checks, and support for Xbox, PlayStation, Switch, and PC pads. This site covers all of them in one place.

    How do I test a gamepad on Android?

    Pair your controller over Bluetooth or USB OTG, open this page in Chrome for Android, and press any button to connect. Buttons, sticks, and triggers test normally. Note that vibration support on mobile browsers is limited, so confirm rumble on desktop.

    What is a gamepad tester used for?

    Common uses include diagnosing stick drift, checking a used controller before buying, verifying a repair, comparing wired and Bluetooth performance, mapping buttons on third party pads, and testing rumble motors.

    What causes stick drift?

    Dust around the stick base and wear of the internal potentiometer are the top causes. Rest readings under ±0.05 are healthy, ±0.05 to 0.12 is minor offset a deadzone can mask, and above ±0.12 is hardware wear.

    How do I test if a controller is bad?

    Run the full check: every button must register once, sticks must rest under ±0.12 with circularity under 25 percent, both triggers should reach 100 percent, and both rumble motors should hum cleanly. Failures in more than one area mean the pad needs repair or replacement.

    Can I test my controller online for a game?

    Yes. Testing here prepares your pad for any game because games read the same inputs this page measures. Competitive players also use the reaction time test to compare connection speed before ranked sessions.

    My gamepad tester is not detecting my controller. How do I fix it?

    Press any button first, since browsers hide gamepads until first input. Then try a USB cable instead of Bluetooth, confirm the cable carries data, use Chrome or Edge on desktop, and close Steam or remappers that can capture the pad exclusively.

    Know your controller before game night.
