Lite Speed Test
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 2โ5% of Ookla Speedtest, but without the heavy ads, account walls, or invasive analytics.
Privacy-conscious users, remote workers, gamers, streamers, webmasters, ISPs, journalists, and researchers who need accurate, transparent, and ad-light speed measurements.
No account. No payment. No compromises.
Speed-CheckSpeed-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.
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.
Speed-Check's answer:
Because it combines accuracy with transparency: M-Lab NDT7 results within 2โ5% 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.
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.
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+).
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.
