GrandSpeed goes far beyond the traditional speed test tools which usually only test upload/download speeds. GrandSpeed tests for these and also checks the idle latency, loaded latency (latency while other activities are happening), jitter, packet loss, bufferbloat. Amazingly, GrandSpeed also automatically determines the maximum video resolution that you can watch as well as maximum video resolution at which you can livestream on your internet!. What is more, GrandSpeed also automatically provides an indication of the degree of suitability of your connection for gaming and audio/video calling or conferencing, based on the measured upload speed, latencies and packet loss. Furthermore, the tool also indicates how much data you can download in an hour and also in 24 hours over your connection, which is useful when planning to bulk download files. There is also a Speed Budget calculator to help you determine the minimum internet service that you should subscribe to, based on the variety of devices on your network. In short, this is simply the best internet quality assessment tool on the planet.

Possible disadvantages of Fast.com

    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.

  • Insufficient Information
    I do not have verified, up-to-date information about GrandSpeed (grandspeed.net) in my training data, and I am unable to browse the internet to access the website directly. Therefore, I cannot provide accurate, specific pros for this service.

GrandSpeed's answer:

GrandSpeed came about as a result of difficulties we were experiencing with getting smooth video livestreams and we could not find any tool that provides useful information regarding the suitability of the often unstable internet connection that we were using for livestreaming video. hence, we decided to come up with a tool for this purpose. However, this tool is useful for many other purposes including gaming, VoIP calls etc.
