Questions & Answers

As answered by people managing Codewars and HardwareTest.org.

Who are some of the biggest customers of your product?

HardwareTest.org's answer:

Members of the r/pcmasterrace community

Competitive FPS Gamers (CS2, Valorant, Apex Legends players)

PC Hardware Reviewers and Tech Enthusiasts

IT Support Professionals

Why should a person choose your product over its competitors?

HardwareTest.org's answer:

The main competitors are native driver suites like Razer Synapse or Logitech G-Hub, which are often criticized for being "bloatware" (requiring 500MB+ storage, mandatory logins, and background processes). Hardware Test Pro offers a lightweight alternative: it loads instantly in your browser, requires no account, and collects no user telemetry. Compared to other web-based testers, it offers superior accuracy for high-performance gaming gear and includes a comprehensive suite of tools (Dead Pixel, Stick Drift) rather than just a single function.

How would you describe the primary audience of your product?

HardwareTest.org's answer:

Our primary audience consists of competitive PC Gamers (FPS/MOBA), Esports enthusiasts, and PC Builders who need to verify their hardware performance. It is also widely used by IT professionals and hardware reviewers for quick troubleshooting (sanity checks) to diagnose if a mouse sensor is spinning out, if a controller has stick drift, or if a new monitor has dead pixels, without modifying the system software.

What makes your product unique?

HardwareTest.org's answer:

Hardware Test Pro is the first privacy-first, browser-based diagnostic suite that solves the "1000Hz limitation" of web browsers. Unlike standard web tools that are capped by monitor refresh rates, we utilize advanced APIs (like getCoalescedEvents) to capture raw high-frequency input data. This allows users to accurately test 1000Hz, 4000Hz, and 8000Hz mouse polling rates and visualize sensor stability without installing a single byte of software. It combines Mouse, Gamepad (Stick Drift), and Screen diagnostics in one zero-install, zero-login package.

What's the story behind your product?

HardwareTest.org's answer:

The project started from a personal frustration: I bought a new gaming mouse and wanted to check its polling rate, but realized I had to install a 500MB driver suite just to see a single number. I decided to build a "No-Install" solution. After launching the MVP on the r/pcmasterrace subreddit, it went viral, resonating with thousands of gamers who were tired of invasive driver software. It has since evolved from a simple mouse tester into a complete hardware diagnostic hub driven by community feedback.

Which are the primary technologies used for building your product?

HardwareTest.org's answer:

Hardware Test Pro is built with a modern, performance-focused stack:

Frontend: React & Next.js for a fast, reactive UI.

Styling: Tailwind CSS for a clean, responsive design.

Core APIs: High Resolution Time API (performance.now) and Pointer Events API (getCoalescedEvents) to bypass the browser event loop for microsecond-precise input tracking.
