Honest Browser Methodology<br>ControllerTest reads the Gamepad API locally. It can reliably show input state, stick center offset, trigger values and browser-exposed haptics.<br>Polling rate is estimated from browser timestamps, so use it for setup comparisons rather than hardware-lab certification.

Complete Controller Diagnostics<br>Run input checks, drift sampling, deadzone guidance, circularity, polling estimates, trigger reads and vibration capability checks from one local browser tool.
Button Input Mapping<br>Press face buttons, bumpers, stick clicks, menu buttons and D-pad directions while the visualizer highlights the browser-visible input.<br>Stick Drift Sample<br>Keep both sticks untouched for a timed sample and review center offset, drift severity and a practical in-game deadzone suggestion.<br>Deadzone Helper<br>Translate idle stick noise into a realistic game setting without claiming to recalibrate or repair controller hardware.<br>Circularity Test<br>Rotate the stick around the full gate to visualize travel coverage, max radius and circularity error.<br>Polling Rate Estimate<br>Compare wired, Bluetooth and 2.4G modes with browser-level Gamepad timestamp sampling and stability notes.<br>Vibration Capability<br>Detect browser-exposed haptic support and run weak or strong rumble pulses when the controller, browser and driver allow it.
Controller Health Report<br>Summarize drift, polling stability, trigger range, vibration capability and export-ready notes in one workflow.
Built For Real Controller Checks<br>A controller tester should do more than flash buttons. This MVP is designed around buying used controllers, diagnosing repairs and exporting repeatable results.
Used Controller Check<br>Run a quick condition pass before buying or selling. Check button responsiveness, stick drift, triggers, vibration support and overall health score.
Repair Technician Export<br>Download JSON or CSV for service notes, warranty claims, before/after repair comparisons and customer screenshots.
Device-Specific Testing<br>Use the same diagnostic engine for Xbox, DualSense, DualShock, Switch Pro, Joy-Con and generic PC controllers.
How To Test A Controller<br>Use the same repeatable flow for a new controller, a used marketplace purchase or a repair before-and-after check.
01Connect and wake<br>Connect by USB, Bluetooth or adapter, then press any controller button so the browser can expose the Gamepad API device.
02Check raw inputs<br>Press every button, move both sticks and pull both triggers slowly. Watch for missing input, stuck values or jitter at rest.
03Run health diagnostics<br>Sample drift, estimate deadzone, rotate for circularity and compare polling stability under the same browser and system.
04Export the report<br>Copy a concise health summary or export JSON, CSV and a share card for resale checks, repair notes or support tickets.
Accuracy And Browser Support<br>Browser controller testing is useful, but not every result has the same precision. Use this matrix to understand what is measured directly and what should be treated as an estimate.
