About Gamepad Test App
Browser controller testing made simple and accessible
Our Mission
Gamepad Test App was created to help players check their controllers before problems show up the hard way during a match or after a trip to a repair shop. The goal is simple: make browser-visible controller checks easy to run and easy to interpret without pretending that a web page is an electrical lab.
Who Runs This Site
Gamepad Test App is built and maintained by Furqan, a web app developer who has also developed two Android apps. I built this tool because controller problems are often noticed too late: when a stick starts drifting in-game, a trigger does not reach full range, or a button starts behaving oddly.
I personally use a PS5 DualSense controller, though lately I have had less time to play than I would like. That is part of why this project matters to me: when gaming time is limited, a quick browser test can help confirm whether the controller is ready before the session starts.
The repair and troubleshooting guides are reviewed when the tester or its evidence limits change, and they begin with repeat tests, official tools, and reversible checks before suggesting invasive work.
What We Offer
Evidence-Based Testing
- - Documented checks with required actions and minimum evidence
- - Repeated stick-center and sweep sampling
- - Per-control button and per-side trigger results
- - Repeated per-axis snapback observations
- - Supported vibration commands with user confirmation
- - Browser input timeline and extra-axis activity
- - Pending health until eligible evidence coverage is sufficient
- - Live comparison without repair or health verdicts
Advanced Features
- - Session Isolation: Disconnects and controller changes cannot inherit old evidence
- - Shared Sampling: Visualization and tests consume one timestamped input stream
- - Audio Assist: Sound feedback for inputs
- - Semantic input-profile calibration for nonstandard mappings
- - Browser-observed cadence with confidence and contamination notes
- - Versioned local history with deletion controls
- - Immutable JSON, text, CSV, and final PNG exports
- - Explicitly associated experimental DualSense and DualShock 4 WebHID output
- - Registry-driven methodology and measurement limits
