Requestly is a modern and powerful companion for API Development and Testing. It is an open-source tool purpose-built to speed up and simplify API development workflow for developers and QAs. It is a combination of API Client and HTTP Interceptor that helps create and share API Contracts, testing APIs, and easily mock and integrate them into web and mobile apps.
Hardware Test Pro is a privacy-first, browser-based hardware diagnostic suite designed to replace invasive driver software.
Gamers and PC builders often have to install heavy "bloatware" (like Razer Synapse or Logitech G-Hub) just to check if their devices are working. Hardware Test Pro solves this by providing a professional testing hub that runs entirely in your browser. It requires no installation, no login, and zero data collection.
Unlike standard web tools, we utilize advanced APIs (like getCoalescedEvents) to bypass frame-rate limitations. This allows for accurate visualization of high-performance mouse sensors (1000Hz+) and precise stick drift analysis previously only possible with native apps.
Key Features:
๐ฑ๏ธ Mouse Polling Rate Test: Accurately measure Hz stability (125Hz to 8000Hz). Detects sensor spin-outs and jitter in real-time.
๐ฎ Gamepad Tester: Visualize analog stick drift, test deadzones, and verify vibration on Xbox, PS5 (DualSense), and generic controllers.
๐ฅ๏ธ Dead Pixel Tester: Professional screen cycle tool (RGB/CMYK/White/Black) to detect dead pixels, stuck pixels, and backlight bleeding.
โจ๏ธ Keyboard Tester: Verify N-Key Rollover (NKRO) and check for ghosting or chattering keys on mechanical keyboards.
โก Click Speed Test (CPS): Benchmark your clicking speed with 10s/30s/60s timers and detailed CPM analytics.
๐ฑ๏ธ Mouse Button Tester: A dedicated tool to check for "double-click" switch failures and verify scroll wheel steps.
๐ Audio Tester: Verify Left/Right channel separation, frequency response, and microphone clarity.
Why Use It? Perfect for Esports gamers, PC builders checking used hardware, or IT pros troubleshooting peripherals. Diagnose hardware glitches instantly without cluttering your system with driver software.

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.
Requestly's answer
Requestly is an open-source API development and testing tool that combines the capabilities of an API Client and HTTP Interceptor, making it a better alternative to Postman + Charles Proxy. It simplifies API mocking, request modification, and debugging with an intuitive no-code interface, enabling developers and QAs to test APIs efficiently.
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.
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.
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.
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.
Perfect for quickly testing peripherals. I buy and sell a lot of used controllers and mice, and this site saves me so much time. No login, no downloads, just plug and test. The gamepad tester instantly showed me the stick drift on my old Xbox controller. Clean interface and privacy-focused. 10/10
