Complete Online Controller Test & Hardware Diagnostics
Whether you are calibrating a brand-new PlayStation 5 DualSense edge controller, testing a custom SCUF controller, or troubleshooting an older Xbox One gamepad with stick drift, having an instantaneous browser-based gamepad tester is essential. Our online gamepad tester leverages the HTML5 W3C Gamepad API to stream sub-millisecond polling data directly from your controller drivers without installing third-party software or executables.
Modern competitive gaming in titles like Rocket League, Apex Legends, Call of Duty Warzone, EA FC 24, Fortnite, and Street Fighter 6 requires razor-thin input precision. Even a slight 2% deadzone offset or a sticky bumper button can cause dropped inputs, false directional directional inputs, or erratic camera panning during intense clutch moments.
Analog Stick Precision Telemetry
The left and right analog stick modules measure coordinate displacement across X and Y Cartesian axes from -1.000 to +1.000. Our live stick visualizer displays both digital floating-point values and a 2D position crosshair, allowing you to detect stick drift, circularity error, and non-linear outer deadzones.
Analog Trigger Pressure Sensitivity (LT / RT)
Analog triggers (L2 and R2 on PlayStation, LT and RT on Xbox) feature magnetic Hall effect or resistive potentiometers that output granular 0% to 100% force values. Our trigger pressure bars display exact activation depth so you can verify trigger stop triggers and hair-trigger mods.
