Questions & Answers

As answered by people managing JoyCheck.
  1. What makes JoyCheck unique?

    JoyCheck (Gamepad tester) reads your controller through the W3C Gamepad API and shows the raw input value on every animation frame, with no smoothing or averaging applied on top. It runs entirely client-side, so nothing you do leaves your browser. No install, no account, no telemetry. It reads stick-drift severity in about 30 seconds and covers buttons, sticks, triggers, and vibration in a single pass.

  2. Why should a person choose JoyCheck over its competitors?

    Most controller testers make you install software, create an account, or run your inputs through a server. JoyCheck does none of that. It is free, works in any modern browser on any controller the Gamepad API recognizes, and keeps your data on your own machine. It also pairs the tester with plain-language guides on drift, deadzones, calibration, and repair, so you can act on what the numbers tell you.

  3. How would you describe the primary audience of JoyCheck?

    Gamers troubleshooting a controller they suspect is drifting or faulty, hardware reviewers measuring stick behavior, and anyone who wants a quick, no-install way to confirm that every button, stick, trigger, and motor works before or after a repair.

  4. What's the story behind JoyCheck?

    JoyCheck was built by Taimoor Bamazai, founder of Elites Algorithm Limited, out of frustration that every gamepad tester either bundled ads, required an install, or sent controller data to a server. The goal was a fast, privacy-first tool that reads the controller directly in the browser and tells you the truth about your hardware in under a minute.

  5. Which are the primary technologies used for building JoyCheck?

    JoyCheck is built on the W3C Gamepad API, including the Gamepad Extensions haptics interface for vibration. The site is a static, dependency-free build made with Astro, and all controller reading happens client-side in vanilla JavaScript with no backend processing of your input.
