Empowering Gamers With Zero-Latency Diagnostics
ControllerTesting.com was built to solve a simple problem: diagnosing stick drift, input delay, and button wear should never require installing heavy software, creating user accounts, or paying for basic checkups.
100% Client-Side Processing
All hardware signals, analog coordinates, and button press telemetry are computed live inside your browser using standard HTML5 APIs. Zero data ever leaves your device.
Sub-Millisecond Precision
Engineered with 60Hz/120Hz canvas render loops and 0.1% axis sampling threshold for professional esports players, speedrunners, and hardware repair technicians.
Universal Peripheral Coverage
Instant native support for PS5 DualSense, PS4, Xbox Series X/S, Nintendo Switch Pro, Joy-Cons, Fight Sticks, Flight HOTAS, WebMIDI keyboards, and 8KHz gaming mice.
Empirical Reliability Database
Modeled reference baselines for comparing Hall-Effect vs potentiometer degradation across 12-month wear cycles — every consenting tester adds a real data point to the community curve.
Our Technical Architecture & Philosophy
Modern controllers rely on complex potentiometer micro-sensors and Hall-Effect magnetic sensors that deteriorate over thousands of gaming hours. Standard operating systems provide basic game controller test panels, but lack precise circularity calculation, drift timeline telemetry, and pressure linearity curve visualization.
We developed a lightweight, standard-compliant browser suite utilizing HTML5 Gamepad API polling loops capable of running up to 1000Hz (1ms interval sampling). By computing mathematical range-of-motion maps directly on your GPU/CPU thread, we guarantee instant response times with total privacy.
