What each product offers, as listed by its team.

Fast.com 5 features
Blitz.js 5 features
  • Simplicity
    Fast.com has a clean and straightforward interface, making it very easy for users to test their internet speed without any distractions or complications.
  • Ad-Free
    The website does not contain any advertisements, providing a seamless and uninterrupted user experience.
  • Integration with Netflix
    Fast.com is created by Netflix, which ensures that the speed test results are optimized for streaming services, giving users a reliable indicator of how well they can stream content on the platform.
  • Quick Results
    The speed test begins automatically as soon as the website loads, providing users with rapid results without the need for additional clicks or inputs.
  • Mobile-Friendly
    Fast.com is optimized for mobile devices, making it easy for users to test their internet speed on smartphones and tablets.

Possible disadvantages

  • Limited Metrics
    Fast.com primarily focuses on download speed and does not provide as comprehensive a range of metrics as some other speed test websites, such as upload speed, latency, and jitter.
  • No Server Selection
    Users cannot choose which server to run the speed test against, which can sometimes result in less accurate measurements for specific network conditions.
  • No Historical Data
    Fast.com does not offer features to save or track historical speed test results, limiting users' ability to monitor their internet performance over time.
  • Lack of Customization
    There are no options to customize the test parameters, such as test duration or concurrency levels, which might be relevant for more advanced users.
  • Geared for Streaming
    Since Fast.com is tailored for Netflix streaming, it may not fully represent other usage scenarios, such as gaming or file downloads, which require different network performances.
  • Fullstack Framework
    Blitz.js provides a cohesive experience by integrating both frontend and backend, enabling developers to focus more on building features than managing infrastructure.
  • Built on Next.js
    Being built on Next.js, Blitz.js benefits from the mature, well-maintained foundation of Next.js including its advanced routing, rendering optimizations, and powerful features.
  • Zero-API Data Layer
    Blitz.js eliminates the need for REST or GraphQL for client-server communication by allowing direct database access across the app, simplifying data management.
  • Community and Plugins
    A vibrant community and a growing ecosystem of plugins make it easier to extend and customize Blitz.js applications.
  • Authentication
    Blitz.js comes with built-in authentication and authorization, reducing the time and effort needed to implement security features in applications.

Possible disadvantages

  • Learning Curve
    For developers coming from traditional REST or GraphQL backgrounds, adjusting to Blitz.js's paradigm, especially the data layer, may take some time.
  • Early Stage
    As Blitz.js is relatively new, it may lack the stability, full-fledged documentation, and extensive community support found in more established frameworks.
  • Opinionated
    Blitz.js follows specific conventions and patterns, which might limit flexibility for developers wanting to deviate significantly from its architecture.
  • Compatibility
    Some existing libraries or tools might not yet fully support or integrate seamlessly with Blitz.js, potentially requiring additional effort or workarounds.
  • Performance Overhead
    The zero-API approach, while simplifying development, might introduce unanticipated performance overheads in certain scenarios, especially with large-scale data operations.

    That is exactly how fast.com works for internet speed tests. You open it, it runs, you see a number. Done. - Source: dev.to / 5 months ago
  • Streaming the 2026 Winter Olympics: A Developer's Guide to Live Sports IPTV
    Pro tip: Run a speed test immediately before the event. Don't trust your "up to 100 Mbps" ISP claim. Use fast.com or speedtest.net to get real numbers. - Source: dev.to / 8 months ago
  • Downdetector, Speedtest sold to IT service provider Accenture in $1.2B deal
    Speedtest has always seemed incredibly sketchy to me, I don’t know if others share this sentiment. https://fast.com completed the test faster than speedtest loads the site. - Source: Hacker News / 9 months ago
