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 — 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 2–5% of Ookla Speedtest, but without the heavy ads, account walls, or invasive analytics.

Key Features

  • Full metrics by default — download, upload, ping, and jitter (no hidden upload like Fast.com)
  • 🔒 Privacy-first — no cookies, no personal data stored, GDPR-compliant
  • 🌍 Global server network — M-Lab + Cloudflare endpoints worldwide
  • 🧩 Free embeddable widget — add a speed test to any website in 3 sizes (no paid tier)
  • 🧪 Open methodology — protocol and code logic publicly documented
  • 📱 Apps & extensions — Progressive Web App (PWA), Chrome extension (Manifest V3), Firefox extension (140+)
  • 📊 Country rankings — broadband and mobile speeds for 200+ countries
  • 📚 Knowledge hub — in-depth guides on WiFi, VPN, gaming ping, streaming, and more

Who It's For

Privacy-conscious users, remote workers, gamers, streamers, webmasters, ISPs, journalists, and researchers who need accurate, transparent, and ad-light speed measurements.

React Server features and specs

  • Server-side rendering built-in
    React Server provides built-in server-side rendering (SSR) out of the box, which improves initial page load performance and SEO without requiring complex custom setup.
  • Fast page transitions
    React Server supports fast client-side page transitions after the initial server render, giving users a smooth single-page application experience while retaining SSR benefits.
  • Built on React
    Since it is built on top of React, developers already familiar with React can leverage their existing knowledge and the vast React ecosystem of components and libraries.
  • Code splitting and lazy loading
    React Server supports automatic code splitting and lazy loading of components, which helps reduce the initial bundle size and improves page load times for end users.
  • Simplified SSR configuration
    Compared to setting up SSR manually with React, React Server abstracts away much of the complexity involved in server rendering, routing, and hydration, making it easier to get started.

Possible disadvantages of React Server

  • Small community and ecosystem
    React Server has a relatively small community compared to mainstream frameworks like Next.js or Remix, which means fewer tutorials, third-party plugins, and community support resources are available.
  • Limited maintenance and updates
    The project has seen limited active development and maintenance over time, raising concerns about long-term viability, bug fixes, and compatibility with newer versions of React.
  • Sparse documentation
    The documentation for React Server is not as comprehensive or well-maintained as that of more popular alternatives, making it harder for new developers to learn and troubleshoot issues.
  • Fewer features compared to alternatives
    Compared to mature frameworks like Next.js, React Server lacks many modern features such as API routes, built-in image optimization, incremental static regeneration, and a rich plugin ecosystem.
  • Risk of project abandonment
    Given the low activity on the project's repository and the dominance of competing frameworks, there is a risk that the project may become abandoned, leaving adopters without future support or updates.

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 Server

Overall verdict

  • React Server (react-server.io) is a specialized framework for building server-rendered React applications with a focus on performance and simplified architecture, but I don't have verified, up-to-date information confirming its current status, adoption, or quality compared to alternatives like Next.js or Remix. I'd recommend researching current reviews and documentation directly before making a decision.

Why this product is good

  • Claims to offer server-side rendering capabilities for React applications
  • May provide an alternative approach to SSR compared to more established frameworks
  • Specific technical merits would depend on your project requirements and current documentation

Recommended for

  • Developers researching alternative SSR solutions for React
  • Teams willing to evaluate niche or less mainstream frameworks
  • Projects where established frameworks like Next.js don't fit specific architectural needs
  • Users who should verify current features, community support, and maintenance status before adopting

Questions & Answers

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

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 — 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 — 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 2–5% 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 — 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.
