Our Mission

We built MyGpadTester because we were tired of buying "working" controllers that weren't actually working. Stick drift, dead buttons, and weak rumble are more than just annoyances—they cost money and ruin gaming sessions. We wanted to create a space where you don't have to guess if your hardware is failing.

Our tools utilize the W3C Gamepad API—the same standard trusted by browsers like Chrome and Edge—to read raw input from your PS5, Xbox, Nintendo, or PC controller directly. What you see on your screen is the unfiltered truth of what your hardware is sending, helping you decide whether to calibrate, repair, or replace your gear.

Hardware-Focused Precision

What makes MyGpadTester different? It’s our focus on verifiable hardware data. We don't just show you that a button works; we provide the tools to analyze the axial resolution of your analog sticks. This allows you to identify wear-and-tear in Alps Alpine potentiometers long before you notice it in-game.

Drift Analysis

We monitor stick center-return values to help you set the perfect deadzone for your specific hardware state.

Polling Stability

Our Polling Rate Tester checks the consistency of your controller's communication with your PC.

By understanding the physics of Hall Effect sensors versus traditional carbon-track components, we provide context for your results. Whether you're a competitive player calibrating for a tournament or a casual gamer checking a second-hand purchase, our diagnostic suite is designed for accuracy.

Privacy & Transparency

In an age of constant data collection, we believe your hardware performance is your business. MyGpadTester operates on a Zero-Telemetry Policy. All diagnostic calculations are performed locally on your machine. We do not store hardware IDs, button signatures, or session data. When you close the tab, the data is gone.

We are proud supporters of the Right to Repair movement. Our goal is to provide the data that empowers you to fix your own gear. For more details on how we protect your data, please visit our Privacy Policy.

Marcus Sterling

I am a Certified Hardware Analyst with over 12 years of hands-on experience in gaming peripheral diagnostics. My journey started in the competitive scene where I realized how often "skill issues" were actually hidden hardware failures.

I am professionally certified by iFixit as a Master Tech, and I've spent years analyzing Hall Effect sensors to solve the industry's stick drift crisis. I built MyGpadTester to give every gamer the same pro-level diagnostic tools I use on my own workbench.
