Features and specs

What each product offers, as listed by its team.

Fast.com 5 features
Lightly 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.
  • Efficient Data Curation
    Lightly uses active learning and self-supervised learning techniques to help teams select the most valuable and diverse subset of data for labeling, reducing the amount of data needed for training while maintaining model performance.
  • Reduces Labeling Costs
    By intelligently selecting which images or videos to label, Lightly can significantly cut down on the manual annotation costs and time required for building computer vision datasets.
  • Self-Supervised Learning Integration
    The platform leverages self-supervised learning methods to extract meaningful embeddings from unlabeled data, enabling better understanding of dataset structure and redundancy before labeling.
  • Scalable for Large Datasets
    Lightly is designed to handle large-scale image and video datasets, making it suitable for enterprises dealing with massive amounts of visual data in computer vision projects.
  • Integration with ML Workflows
    Lightly offers APIs and integrations that allow it to fit into existing machine learning pipelines, working alongside popular annotation tools and cloud storage solutions.

Possible disadvantages

  • Learning Curve
    Teams new to active learning and self-supervised learning concepts may face a learning curve in understanding how to best utilize Lightly's data curation capabilities.
  • Narrow Use Case Focus
    Lightly is primarily focused on computer vision data curation, which may limit its usefulness for teams working with other data types such as text, audio, or tabular data.
  • Dependency on Data Quality
    The effectiveness of Lightly's curation algorithms depends heavily on the quality and representativeness of the initial dataset, which can limit results if the source data is poor.
  • Pricing for Smaller Teams
    Depending on the pricing tier, smaller teams or individual developers might find the cost of enterprise-level data curation features less accessible compared to open-source alternatives.
  • Requires Technical Expertise
    Effectively leveraging Lightly's advanced features like self-supervised learning models may require a certain level of machine learning expertise, which could be a barrier for less technical teams.

  • I Built a Fast.com for LLMs: Introducing iamspeed.dev
    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 / 8 months ago
