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.

Key Features

  • โšก Full metrics by default โ€” download, upload, ping, and jitter (no hidden upload like Fast.com)
  • 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)
  • ๐Ÿงช Open methodology โ€” protocol and code logic publicly documented
  • ๐Ÿ“ฑ Apps & extensions โ€” Progressive Web App (PWA), Chrome extension (Manifest V3), Firefox extension (140+)
  • ๐Ÿ“Š Country rankings โ€” broadband and mobile speeds for 200+ countries
  • ๐Ÿ“š Knowledge hub โ€” 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.

SuperCoder features and specs

  • Automated Coding Assistance
    SuperCoder leverages AI agent capabilities to automate coding tasks, potentially speeding up development workflows by handling repetitive or boilerplate coding work.
  • Built on SuperAGI Framework
    As an agent template within the SuperAGI ecosystem, it benefits from the underlying framework's infrastructure, tooling, and community support for autonomous agents.
  • Customizable Template
    Being a template, it provides a starting point that developers can adapt and configure for their specific coding project needs rather than building an agent from scratch.
  • Open Source Nature
    SuperAGI and its agent templates are typically open source, allowing developers to inspect, modify, and extend the code to fit their specific use cases without vendor lock-in.
  • Integration Potential
    Being part of a broader agent ecosystem, SuperCoder can potentially integrate with other tools, APIs, and agents within the SuperAGI platform for more complex automated workflows.

Possible disadvantages of SuperCoder

  • Learning Curve
    Users unfamiliar with the SuperAGI framework or agent-based architectures may face a steep learning curve to effectively configure and use SuperCoder for their projects.
  • Limited Documentation
    As a relatively newer or niche tool, documentation and community resources may be less mature compared to more established coding assistants, making troubleshooting harder.
  • Dependency on SuperAGI Ecosystem
    Being tied to the SuperAGI platform means users must adopt or work within that ecosystem, which could be a constraint if they prefer standalone tools.
  • Potential Reliability Issues
    AI coding agents can sometimes produce inconsistent or incorrect code suggestions, requiring careful human review and validation before deployment.
  • Setup Complexity
    Configuring an autonomous coding agent template may require more technical setup (API keys, environment configuration, model access) compared to simpler code completion tools.

Questions & Answers

As answered by people managing Speed-Check and SuperCoder.

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.
