Questions & Answers

As answered by people managing Mouse Tester and Eloquent JavaScript.

What makes your product unique?

Mouse Tester's answer

Mouse Tester combines a visual button map (left/right/middle/side buttons) with targeted diagnostics for two of the most common real-world issues: unintended double-clicks and scroll wheel jumping/direction problems. It’s designed to be fast, simple, and instantly understandable—so users can confirm what’s happening within seconds.

Who are some of the biggest customers of your product?

Mouse Tester's answer

Mouse Tester is currently aimed at the general public and support use cases rather than enterprise accounts. Users typically include individuals troubleshooting peripherals, gamers, and IT/helpdesk staff who need quick browser-based verification. (If you have specific customer names or logos later, you can add them here.)

Why should a person choose your product over its competitors?

Mouse Tester's answer

Mouse Tester focuses on the checks people actually need when a mouse feels “off”:

  • Clear visual feedback for every button press (including side buttons)

  • Practical double-click issue detection to spot unintended repeats

  • Scroll wheel jump/direction checks to catch erratic scrolling

It’s also lightweight and straightforward—no installs, no accounts, and a clean UI that gets you to a result quickly.

How would you describe the primary audience of your product?

Mouse Tester's answer

Mouse Tester is built for:

  • Everyday users troubleshooting mouse issues at home or work

  • Gamers who want to verify clicks, side buttons, and scroll behavior

  • IT/support teams who need a quick way to validate mouse input in a browser

  • Anyone buying/repairing peripherals who wants a simple verification tool

What's the story behind your product?

Mouse Tester's answer

Mouse Tester started as a practical fix for a common problem: when a mouse begins double-clicking or the scroll wheel starts jumping, it’s hard to prove the issue quickly. The goal was to create a browser-based tester that makes mouse input visible and easy to diagnose—so users can confirm the problem before changing settings or replacing hardware.

Which are the primary technologies used for building your product?

Mouse Tester's answer

Mouse Tester is a web app built with a modern front-end stack:

  • Next.js (static export / no-backend deployment)

  • React + TypeScript

  • Tailwind CSS and shadcn/ui for UI components
    Core diagnostics are implemented with standard browser mouse and wheel events.
