Gamepad Tester: Check Your PS5, PS4, Xbox, and PC Controller
Test your controller directly in your browser and check buttons, sticks, triggers, and other inputs in real time.
Getting Your Controller Recognized
The tool detects controllers through two connection methods: USB and Bluetooth. Both are supported across desktop and mobile browsers.
USB
Connect the controller to any open USB port. This method works with wired pads, USB wireless receivers, and most third-party adapters. Detection happens at the operating system level, so any controller the OS recognizes will also be recognized by Gamepad Tester.
Bluetooth
Pair the controller through the device's Bluetooth settings first. Once pairing is confirmed, press any button on the controller to activate the tool's detection.
A Four-Step Walkthrough for Testing Any Controller
Gamepad Tester checks buttons, analog sticks, triggers, the D-pad, rumble motors, and stick drift. The following four steps cover a complete diagnostic pass.
Step 1 โ Get the Controller Recognized
Connect the controller over USB or Bluetooth. The Web Gamepad API only activates after a button is pressed, which is a browser security requirement rather than a limitation of the tool. Once a button is pressed, the controller's name and index appear automatically. Up to four controllers can be tested at the same time.
Step 2 โ Run Through Every Input
Press each face button, bumper, trigger, stick click, D-pad direction, and system button in turn, checking that the corresponding on-screen indicator activates. An Input History log records every press and release with a timestamp, so earlier results can be reviewed at any point. A built-in 60-second Quick Test provides a fast pass/fail summary for users who don't need a full session.
Step 3 โ Check the Analog Sticks for Drift
Move each stick through its full range while watching the live X/Y readout, then release it and observe where the values settle. A properly functioning stick should rest at 0.000 on both axes; a resting value beyond ยฑ0.05 indicates drift. The Drift Detection panel logs resting samples automatically over time, making intermittent drift easier to catch.
Step 4 โ Check Vibration, Latency, and Health Score
Cycle through Light, Medium, Heavy, and Pulse vibration presets, or use the intensity slider to test each rumble motor individually. The Latency Test measures average input response time. The Health Score, rated 0โ100, combines the results of every test into a single overall rating; a score of 90 or above generally indicates a controller in good working condition. Results can be exported as a text file for later comparison.
Controllers Supported by This Gamepad Tester
Any HID-compliant controller recognized by the operating system will work with Gamepad Tester. The following families receive the most complete feature coverage.
Xbox
Every generation is supported through XInput on Windows and as a standard HID gamepad on macOS and Linux. Button, trigger, and rumble data can be read over USB and Bluetooth where supported by the browser.
PlayStation
DualSense and DualShock controllers provide button mapping, analog trigger readings, and standard gamepad input through compatible browsers and operating systems.
Nintendo
The Switch Pro Controller connects through USB and Bluetooth on supported platforms. Joy-Con pairs can also register as a combined gamepad depending on the operating system and browser.
Third-Party and Generic Pads
USB HID-compliant controllers and paired Bluetooth controllers can be detected without extra setup when exposed through the browser Gamepad API. Compatibility depends on the input data reported by each device.

Controller Not Responding? Try These Fixes
If a controller isn't showing up, or inputs seem inaccurate, the following steps resolve most detection issues.
Reload the page
A controller connected before the page finished loading can be missed. Refresh and press a button to re-trigger detection.
Check the connection
Confirm the USB cable is fully seated at both ends and carries data. For Bluetooth, confirm pairing is complete before opening the tool.
Use Chrome or Edge
These browsers offer the most complete Gamepad API implementation, including vibration support.
Grant permissions
Some browsers prompt for permission before reading controller input. Reset permissions from browser settings if needed.
Charge battery
A low battery can cause disconnects, input lag, or phantom presses. Charge or replace batteries.
Update drivers
Check Device Manager for controller issues and update or reinstall official drivers.

Under the Hood: How Gamepad Tester Reads Your Controller
Gamepad Tester surfaces the live state of a connected controller: which buttons are pressed, where the sticks are positioned, and how hard a trigger is being pulled.
Establishing the connection.
Controllers connect by USB cable, Bluetooth pairing, or a 2.4GHz wireless dongle. Once connected, the controller sends a handshake signal, and the host device identifies the controller type โ Xbox, PlayStation, or generic.
Reading input signals.
Each input type reports a different signal range: digital buttons report 0 (not pressed) or 1 (pressed); analog triggers report a pressure value from 0 to 255; analog sticks report X and Y axis values from -1.0 to +1.0.
Processing on the controller.
A microcontroller inside the controller reads every sensor, converts analog signals into digital data, bundles the results into a controller report, and sends that report to the host device at roughly 1000Hz.
Reading the data.
Gamepad tester reads this data through the platform's available API: DirectInput and XInput on Windows, the HTML5 Gamepad API in the browser, and evdev or SDL on Linux. The software decodes each packet and maps it to the corresponding on-screen element โ buttons highlight when pressed, a dot tracks stick position, a bar fills to show trigger pressure, and D-pad arrows light up per direction โ all updated live, which makes faulty buttons, dead zones, or drifting sticks immediately visible.

Common Controller Problems & How to Fix Them
Identify controller issues faster with live diagnostics, practical troubleshooting steps, and gaming-focused hardware checks.
Analog Stick Drift
Signs include unprompted character or camera movement. Confirm in the tool by leaving the stick untouched, then rotate it through its full range. Clean around the stick base and recalibrate before considering joystick replacement.
Button Lag & Input Delay
Signs include delayed actions and inconsistent response. Try a wired connection, close background applications, swap the cable or port, and update firmware and drivers.
Connectivity Problems
Signs include a controller that isn't detected or disconnects randomly. Charge fully, try a different cable or port, re-pair Bluetooth, and reinstall HID drivers if needed.
Trigger Calibration Issues
Signs include triggers that won't reach full range or feel sticky. Check the live trigger values, recalibrate in system settings, clean the mechanism, and replace worn springs if necessary.
Vibration Problems
Signs include weak or absent rumble. Confirm vibration is enabled, run the vibration test, update firmware, and replace the motor if it stays unresponsive.
Controller Detected but Nothing Registers
Try switching input mode between XInput and DirectInput, enabling controller support in the game's settings, and reinstalling drivers.
Ongoing Maintenance
Run a monthly check, recalibrate after long sessions, keep the controller clean and dry, and use wired mode for competitive play.
When to Replace Rather Than Repair
Persistent drift after recalibration, buttons that won't register consistently, unstable axis readings, or repair costs exceeding a new controller's price all point to replacement.
Testing Across Platforms
Check how controller detection and input behavior can change across Windows, PlayStation, Android, and iOS.
| Platform | Input Method | What Gets Detected | Notes |
|---|---|---|---|
| Windows | XInput / HID | Drift / Lag / Vibration | Broadest feature support |
| PlayStation | Proprietary Protocol | Stick / Button | No adaptive trigger data |
| Android | Bluetooth / USB-OTG | Latency / Mapping | Varies by device |
| iOS | MFi / Bluetooth | Basic Input | No haptics or trigger data |
Because results can vary by platform, it's worth testing each device separately, recalibrating after switching platforms, and saving platform-specific calibration profiles where possible. Using a wired connection is recommended whenever accuracy matters most.
