Precision Hardware Diagnostics, Redesigned for the Web
JoystickTester.com was built to replace slow, outdated, and ad-cluttered controller testing sites with a high-performance, dark-mode hardware laboratory.
Our Engineering Mission
Competitive gaming and esports require controllers operating with millimeter precision. Whether diagnosing potentiometer stick drift on an Xbox Series X controller, verifying adaptive trigger travel on a PS5 DualSense, or tuning deadzones for FPS shooters, gamers deserve clean, instantaneous, 3-decimal float readouts without downloading suspicious third-party executables.
Zero-Telemetry & 100% Client-Side Privacy
Unlike other platforms that log device serials or track user metrics, JoystickTester.com processes 100% of joystick coordinate math, button actuation loops, and haptic vibration triggers directly in your browser's local JavaScript execution context.
No controller input strings, timestamps, or hardware signatures are ever saved, stored, or transmitted to any server. Your inputs remain completely private to your local computer.
