About GamepadScan
The Story Behind the Tool
My name is Abdul Hanan, and I’m the developer behind GamepadScan. Like many of you, I’m a competitive gamer. My journey with this project started out of sheer frustration during a high-stakes match. I felt a slight delay in my movements and suspected my controller was failing, but I couldn’t find a lightweight, accurate tool that gave me the raw data I needed without forcing me to download bulky, suspicious software.
I realized that the gaming community didn’t just need a “button checker”—it needed a high-precision diagnostic suite that lived in the browser. So, I built gamepadscan.com.
Why I Built This
Most default windows testers (like the legacy joy.cpl) were designed decades ago. They aren’t built for the 1000Hz polling rates of modern PS5 DualSense controllers or the precision of Hall-Effect sensors.
At GamepadScan, I utilize the latest HTML5 Gamepad API to deliver sub-millisecond input detection. This allows you to visualize:
- True Stick Drift: See raw axis coordinates down to 5 decimal places.
- Input Latency: Measure exactly how long it takes for your signal to reach the browser.
- Vibration Diagnostics: Independent testing for heavy and light rumble motors.
- Trigger Precision: Tracking the “pull curve” for L2/R2 (LT/RT) inputs.
Our Mission: Zero Bloat, Total Accuracy
The mission is simple: Test. Fix. Play. I want to eliminate the “black box” of controller hardware. Whether you are a casual player checking if a used eBay controller works or a pro-gamer “overclocking” your polling rate for Apex Legends or Rocket League, this tool is designed to give you the truth about your hardware.
What Makes Us Different?
- Universal Compatibility: If it has a USB plug or Bluetooth, we can likely test it. From Xbox and PlayStation to Nintendo and generic PC pads.
- Privacy First: As a developer, I value privacy. Your controller inputs are processed locally in your browser; we never store or see your button presses.
- Built for 2026 Hardware: We are constantly updating the code to support new tech like the Switch 2 and the latest high-frequency gaming peripherals.
Looking Forward
GamepadScan is a passion project. My vision is to grow this site into the world’s most trusted hub for controller optimization. I’m constantly writing new troubleshooting guides and adding features based on feedback from the community.
