Gamepad Tester is a free, browser-based controller diagnostic platform trusted by millions of gamers worldwide. Connect any PS5, Xbox, Nintendo Switch, or PC gamepad and instantly test every input — buttons, analog sticks, triggers, vibration motors, and more — in real time, with no downloads, no sign-up, and complete privacy. Every test runs locally in your browser, so nothing is ever sent to our servers.
Gamepad Tester is the most trusted free controller diagnostic platform on the internet. built by gamers, for gamers. For over 13 years we have provided instant, accurate, private controller testing with no downloads, no accounts, and no cost. Whether you are diagnosing stick drift before a ranked match or verifying a new controller out of the box, Gamepad Tester gives you the honest, raw data your hardware is actually sending.
A complete guide to testing how it works your gaming controllers with Gamepad Tester. Press buttons, move analog sticks, pull triggers, and test vibration motors in real time — directly in your browser, no downloads or sign-ups needed.
Follow these four steps to thoroughly test every input on your gamepad and catch any hardware issues before they affect your gameplay.
Connect your gaming controller to your device using USB or Bluetooth. The browser will detect it automatically once you press any button — this is a security requirement of the Gamepad API.
Press each button one at a time and watch the corresponding indicator light up red in the interface. Test every face button, shoulder button, trigger, and D-pad direction methodically.
Move each analog stick slowly through its full range and observe the live X/Y axis values. A healthy stick at rest should read close to 0.000. Any non-zero reading without touching it indicates drift.
Complete your test by checking vibration, reviewing the input log for missed presses, and using the deadzone calibration tool if you notice any minor drift that's affecting your experience.
Gamepad Tester works with any controller that your operating system recognises. Here are the most commonly tested controller families.
Full compatibility with all Xbox controller generations via USB and Bluetooth. XInput support ensures all buttons, triggers, and rumble motors are fully accessible in Chrome, Edge, and Firefox.
Complete support for Sony PlayStation controllers with full button mapping, analog trigger detection, and haptic feedback testing. DualSense and DualShock 4 work best on Chrome and Edge.
Nintendo Switch Pro Controller and Joy-Con pairs are recognised as standard gamepads over USB or Bluetooth. Button mapping follows the standard layout for consistent testing across all inputs.
Any HID-compliant USB gamepad or Bluetooth controller should be detectable, including popular third-party brands. Feature availability varies depending on what the controller reports to the browser.
Connect your controller via USB or Bluetooth to your computer or device
Press any button — the browser Gamepad API activates and identifies your controller
Press buttons, move sticks, and pull triggers — all inputs update live at 60 frames per second
Review the input log, check for drift, test vibration, and identify any failing components
If your controller isn't appearing or inputs aren't registering correctly, work through these fixes in order.
Controllers connected before the page loads may not be detected. Reload the page, connect your controller, then press any button.
Ensure your USB cable is firmly seated, or that Bluetooth is properly paired in your OS settings before opening the tester. Try a different USB port or cable.
Chrome and Edge have the most complete Gamepad API implementation. Firefox works for most controllers, but vibration testing may not be available.
Some browsers ask for gamepad access permission. If you see a prompt, click Allow. If you previously denied it, reset permissions in your browser's site settings.
Low battery causes intermittent disconnections and input lag. Charge your controller fully or replace batteries, then reconnect and test again.
On Windows, open Device Manager and look for any controller entries with warning icons. Right-click and update the driver, or reinstall the manufacturer's software.
Compatible with all modern browsers. Best experience on Chrome 58+, Edge 79+, Firefox 55+, and Safari 16.4+. All input data is processed locally — nothing is sent to any server.
Instant diagnostics for every button, axis, and trigger. Connect a controller or watch the live simulation below.
Test your gamepad online quickly and easily right from your browser—no installs, no accounts, and no hassle. This guide shows you how to connect your controller, check live inputs, and spot common issues in just a few minutes.
Before anything appears on screen, your gamepad needs to be physically connected to your device. You have two options: plug it in via USB, or pair it wirelessly over Bluetooth. Either works. the browser doesn't care which method you use, as long as the controller is recognised by your operating system first.
Most wired controllers connect instantly. PS4, PS5, Xbox One, Xbox Series, and Xbox 360 controllers all work plug-and-play on Windows 10/11 and macOS without installing anything extra.
PS5 and PS4 controllers pair over Bluetooth on any modern device. Xbox controllers use Bluetooth on Series X/S and Xbox One S models. Hold the sync button until the light flashes, then pair from your OS settings.
Visit gamepadtester.co.uk in any modern browser. The tool runs entirely in your browser tab — nothing is installed on your computer and nothing is sent to any server.
The moment the browser detects your controller, the status indicator switches to green. You'll see your controller's full ID string, the number of buttons detected, axes available, and whether haptic feedback is supported.
If your controller doesn't appear, try pressing a button. If it still doesn't show, check your OS Bluetooth or USB device manager to confirm the controller is recognised at the system level first.
Press each button one at a time. A working button lights up red in the interface the instant it's pressed and goes dark when released. No light — something's wrong.

Move each joystick around and watch the X/Y axis values change in real time. A healthy stick at rest should read close to 0.000 on both axes. Drift is when the stick shows non-zero values while you're not touching it.
Once your controller is connected, every panel on the tester updates live at 60 frames per second. Here's what each part of the display means and what normal vs. abnormal readings look like.
Triggers are analogue — they register 0% when untouched and 100% when fully depressed. If a trigger reads non-zero at rest, the spring or sensor may be worn.
Stick drift is when your analog joystick registers movement without you touching it. It's one of the most common controller faults — and Gamepad Tester makes it instantly visible. Leave both sticks untouched and watch the X and Y axis values. Any reading above ±0.05 while the stick is at rest suggests drift. A reading above ±0.15 means the issue will definitely affect gameplay and the controller likely needs cleaning or replacement sticks.
Use the haptic sliders to independently control your controller's left and right rumble motors. Set intensity and duration, then hit "Test Rumble." If you feel nothing on one side, that motor may be failing.
Press every button systematically and watch the indicator grid. A button that never lights up is dead or stuck. A button that lights up without being pressed is physically stuck or the membrane is damaged.
The poll rate shows how many times per second the browser reads your controller's state. Most controllers report at 60Hz, but some USB controllers support 125Hz or higher. A low or erratic poll rate can indicate a USB cable issue, driver problem, or a controller nearing failure.
Bluetooth controllers typically add 8–30ms of additional latency compared to USB. If you're competitive gaming, use USB where possible. You can use the input log in Gamepad Tester to track how consistently your button presses register — large gaps between timestamps indicate dropped inputs.

Common Controller Problems & How to Diagnose Them
Stick drift occurs when a joystick registers movement even when you are not touching it, causing your character or camera to drift uncontrollably.
A button that does not light up when pressed, or one that stays lit without being touched, indicates a physical or electrical fault in the controller.
Analog triggers should smoothly read from 0% at rest to 100% when fully depressed. Anything less suggests wear, debris, or a mechanical fault.
The browser Gamepad API requires a physical button press before recognising a connected controller. This is a security requirement in all modern browsers.
If the rumble test produces no vibration, the issue may be with haptic support in your browser, driver compatibility, or the controller's motors themselves.
High input latency between pressing a button and seeing it register may be caused by Bluetooth interference, USB cable quality, or browser polling rate.
Pro Tips for Better Controller Testing
Low battery can cause inconsistent button response and reduced haptic feedback. Always test with a fully charged or wired controller for accurate results.
Dust and debris under button caps are a common cause of false positives and stuck inputs. A quick clean with compressed air can resolve many apparent faults.
Cold environments can cause analog components to behave erratically. Allow the controller to warm up to room temperature before running a stick drift test.
Bluetooth introduces variable latency. For the most precise input timing and polling rate readings, connect your controller via USB cable during testing.
Intermittent faults may not appear on every test. Run through the full button and stick test at least twice to confirm whether an issue is consistent or occasional.
The timestamped input log records every button press and axis event. Export or screenshot the log to document faults when contacting support or making a warranty claim.

Gamepad Tester was built from the ground up to be fast, private, and genuinely useful, not just another half-baked browser tool. Here's how we compare.
Every other controller testing solution asks you to install an app, create an account, or give away permissions you shouldn't have to. Gamepad Tester opens in your browser tab and starts working the moment you press a button — completely locally, completely privately.
Every button press, axis value, and stick movement is processed entirely within your browser. Nothing is transmitted to our servers. No telemetry. No analytics attached to your inputs. Your controller data is yours, full stop.
The input loop runs at up to 60 polls per second using the native Web Gamepad API — the same speed as a game engine. You see drift, button stutter, and trigger irregularities the instant they happen, not with a half-second delay.
PS5, PS4, PS3, Xbox Series X/S, Xbox One, Xbox 360, Switch controllers, and any generic USB HID gamepad. USB and Bluetooth. Windows, Mac, Linux, and Android. If your OS sees it, we can test it.
Most tools just show you an X/Y readout and leave you to figure out what's normal. We show you resting-state deviation, real-time offset tracking across both axes, and a deadzone calibration tool so you can filter minor drift without replacing your sticks immediately. You see the exact numbers, not just "your stick might have drift."
Test your rumble motors independently. Adjust low-frequency and high-frequency intensity separately, set the duration, and fire the haptic test on demand. You'll know instantly whether one motor is failing, both motors are healthy, or haptic feedback isn't accessible on your current browser and controller combination.
We've done the research so you don't have to. Other controller testing services — whether they're desktop apps, manufacturer tools, or rival browser utilities — all share the same recurring problems: privacy concerns, download requirements, narrow compatibility, and features that simply don't work. Here's an honest breakdown.
