Speed-Check is a free, open, and privacy-first internet speed test that measures your download speed, upload speed, ping, and jitter directly in your browser โ€” no signup, no app install, and no tracking of personal data.

Unlike most mainstream speed tests, Speed-Check runs on the M-Lab NDT7 protocol (the same open measurement standard used by Google Search and independent researchers) combined with Cloudflare edge endpoints for global coverage. Results are typically within 2โ€“5% of Ookla Speedtest, but without the heavy ads, account walls, or invasive analytics.

Key Features

  • โšก Full metrics by default โ€” download, upload, ping, and jitter (no hidden upload like Fast.com)
  • ๐Ÿ”’ Privacy-first โ€” no cookies, no personal data stored, GDPR-compliant
  • ๐ŸŒ Global server network โ€” M-Lab + Cloudflare endpoints worldwide
  • ๐Ÿงฉ Free embeddable widget โ€” add a speed test to any website in 3 sizes (no paid tier)
  • ๐Ÿงช Open methodology โ€” protocol and code logic publicly documented
  • ๐Ÿ“ฑ Apps & extensions โ€” Progressive Web App (PWA), Chrome extension (Manifest V3), Firefox extension (140+)
  • ๐Ÿ“Š Country rankings โ€” broadband and mobile speeds for 200+ countries
  • ๐Ÿ“š Knowledge hub โ€” in-depth guides on WiFi, VPN, gaming ping, streaming, and more

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of Speed-Check

Overall verdict

  • Speed-Check.net is a simple, no-frills internet speed testing tool that provides quick and accessible measurements of download, upload, and ping speeds without requiring installation or account creation.

Why this product is good

  • Free and easy to use with no signup required
  • Provides quick results for download, upload, and ping speeds
  • Accessible directly from a web browser on multiple devices
  • Lightweight interface that doesn't require heavy bandwidth to run the test itself
  • Useful for basic troubleshooting of internet connectivity issues

Recommended for

  • Casual users wanting a quick check of their internet speed
  • People troubleshooting basic connectivity issues at home
  • Users who prefer a simple, ad-light testing experience
  • Those who don't need advanced diagnostics or detailed historical data tracking

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing Speed-Check and React Engine.

How would you describe the primary audience of your product?

Speed-Check's answer

Privacy-conscious internet users, remote workers, gamers, and streamers who want a fast, accurate, no-nonsense speed test โ€” plus webmasters, bloggers, and ISPs looking for a free, embeddable widget. Secondary audiences include journalists and researchers who use the global country rankings and the open M-Lab methodology for citations.

What makes your product unique?

Speed-Check's answer

Speed-Check is an open-source, privacy-first internet speed test built on the M-Lab NDT7 protocol (the same standard Google uses) combined with Cloudflare endpoints. Unlike most competitors, it requires no account, stores no personal data on public pages, runs only a single light ad placement, and offers a completely free embeddable widget โ€” features that are paywalled or hidden elsewhere. It also ships with dedicated Chrome and Firefox extensions, a PWA install option, and detailed country-level rankings, glossaries, and guides.

Why should a person choose your product over its competitors?

Speed-Check's answer

Because it combines accuracy with transparency: M-Lab NDT7 results within 2โ€“5% of Ookla, but without the heavy ads, tracking, video pre-rolls, or mandatory accounts. The embeddable widget is free in three sizes (Ookla charges $300+/month for Speedtest Custom), upload/ping/jitter are shown by default (unlike Fast.com, which hides them), and the entire methodology is open and verifiable. Ideal for users, webmasters, and ISPs who value privacy, fairness, and full metrics.

What's the story behind your product?

Speed-Check's answer

Speed-Check was launched in August 2025 as an independent alternative to the ad-heavy, account-gated speed tests that dominate the market. The goal was simple: build a speed test that respects user privacy, uses open measurement protocols (M-Lab NDT7), and gives back to the web by offering a free embeddable widget and browser extensions โ€” without ever asking for a signup.

Which are the primary technologies used for building your product?

Speed-Check's answer

React 18, Vite 5, TypeScript 5, Tailwind CSS, M-Lab NDT7 (measurement protocol), Cloudflare (CDN and edge measurement endpoints), Supabase (backend/edge functions), and PWA standards. Browser extensions are built on Manifest V3 (Chrome) and the WebExtensions API (Firefox 140+).

Who are some of the biggest customers of your product?

Speed-Check's answer

As a privacy first speed test this is unknown to us. None of our users are being tracked by size and they don't need to sign up on our website.
