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.

  • 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)

Analysis of Code Flex

Overall verdict

  • I don't have verified, specific information about 'Code Flex' at codeflex.pages.dev, as it appears to be a lesser-known or newly launched site hosted on Cloudflare Pages, and I cannot confirm its legitimacy, content quality, or safety without direct access to browse and verify it.

Why this product is good

  • Cloudflare Pages (.pages.dev) is a free hosting platform, meaning this could be anyone's personal, hobby, or unfinished project rather than an established product
  • No verifiable reviews, reputation data, or track record exists in available knowledge to assess trustworthiness
  • The name suggests it may be a coding practice, tutorial, or developer tool site, but its actual purpose, features, and quality are unconfirmed
  • Sites on free hosting subdomains generally warrant extra caution regarding data privacy and content reliability until proven otherwise

Recommended for

  • Users should independently verify the site by checking for an About page, contact information, HTTPS security, and third-party reviews before use
  • Not recommended for entering sensitive personal or payment information without further verification
  • Best approached with caution until legitimacy and purpose are confirmed through direct inspection or trusted reviews

Questions & Answers

As answered by people managing Code Flex and Speed-Check.

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.
