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.

  • Link Control and Security
    Users can set permissions on shared links, including password protection, email requirements, and the ability to disable downloads or revoke access at any time, enhancing document security.

  • No Software Installation Required
    ShareDoc.co is a cloud-based platform that requires no software downloads or installations for either the sender or recipient, making it accessible from any device with a web browser.

Possible disadvantages of ShareDoc.co

  • Limited Free Plan
    The free tier of ShareDoc.co comes with restrictions on the number of documents, links, or tracked views, which may force individuals or small teams to upgrade to a paid plan relatively quickly.
  • Relatively Niche Tool
    ShareDoc.co serves a fairly specific use case around document sharing and tracking, which means it may not replace broader document management or collaboration platforms that teams already use.
  • Dependency on Internet Connectivity
    Since ShareDoc.co is entirely cloud-based, both senders and recipients need an internet connection to upload, share, or view documents, which can be a limitation in low-connectivity situations.
  • Limited Integrations
    Compared to more established platforms, ShareDoc.co may have fewer integrations with popular CRM, productivity, and workflow tools, potentially requiring manual workarounds for some users.
  • Lesser Brand Recognition
    As a smaller platform compared to competitors like DocSend or Google Drive, ShareDoc.co may be less familiar to recipients, which could cause hesitation or trust concerns when clicking shared links.

Analysis of ShareDoc.co

Overall verdict

  • I don't have verified, up-to-date information about ShareDoc.co specifically, so I can't confirm its quality, reliability, or legitimacy.

  • Cannot confirm pricing fairness or value compared to established alternatives

Recommended for

  • Users should independently verify this service's legitimacy before use

Questions & Answers

As answered by people managing Speed-Check and ShareDoc.co.

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.
