Questions & Answers

As answered by people managing Speed-Check and GitHub Skyline.

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.
