LibreSpeed features and specs

  • Open Source
    LibreSpeed is open-source software, meaning anyone can view, modify, and distribute the code. This transparency helps in auditing the code for security issues and allows for community-driven improvements.
  • Free to Use
    LibreSpeed does not require any licensing fees, making it a cost-effective solution for both personal and commercial use.
  • Customizable
    Users can modify the source code to suit their specific needs, whether it is the user interface or the functionality of the speed test.
  • Self-Hosted
    Being self-hosted, LibreSpeed provides more control over data privacy and security, as users can run it on their own servers.
  • No External Dependencies
    LibreSpeed is built to work without relying on third-party services or external dependencies, enhancing reliability and independence.

Possible disadvantages of LibreSpeed

  • Technical Expertise Required
    Setting up and customizing LibreSpeed may require a good degree of technical knowledge, particularly in web development and server management.
  • Maintenance
    Self-hosting LibreSpeed implies that the user is responsible for maintaining the server and updating the software, which could be cumbersome for some.
  • Limited Community Support
    Although it is open source, LibreSpeed may not have as large a user base or as robust community support as more established, proprietary solutions.
  • No Built-In Analytics
    LibreSpeed does not come with built-in advanced analytics or reporting capabilities, so users might need to integrate it with other analytics tools for deeper insights.
  • Initial Setup Complexity
    Configuring the server and ensuring that it works optimally can be complex, particularly for users who are not familiar with server-side configurations.

Ably features and specs

    Due to its wide range of advanced features, the initial learning curve can be steep for new users.
  • Cost
    For large-scale applications or extensive use of advanced features, the costs can add up, making it potentially expensive.
  • Vendor Lock-in
    Relying heavily on Ably’s platform-specific features may result in vendor lock-in, making it challenging to switch to other services in the future.
  • Dependence on Internet Connection
    As a cloud-based service, Ably’s performance is highly dependent on the quality and reliability of the internet connection.
  • Third-party Integration
    While Ably offers various integration options, integrating certain third-party services may require additional custom development or may not be as seamless.

  • Ask HN: Is Comcast ripping me off and how can I prove it?
    Try hosting a DIY speed test on a cloud server (like Google colab or the free oracle instances or whatever): https://github.com/librespeed/speedtest. - Source: Hacker News / about 3 years ago
  • SSLVPN - Fluctuating bandwith
    It should be DIA. They provide the internet connection to the company since 2 decades and it's a very small ISP, so it's very vague in terms of contract. Iperf was giving me very terrible results with TCP, UDP was giving me a couple of Gbit/s throughput, definitely a wrong result. We are using this self hosted speedtest. All my results above are based on this software: Https://github.com/librespeed/speedtest. Source: over 3 years ago
  • Speedtests
    Put a copy of Librespeed on a web server that's accessible through the VPN and told them to use that. For (our) convenience, it's logged into a database that's correlated with the VPN login/logout times so the users don't even need to log in to use it, but we still know whose test result it is.

  • Fooling My ISP
    There is a selfhosted solution for speed testing called LibreSpeed. You could try it and see the results. Source: over 3 years ago
  • How much are you 'trusting' a docker image from hub.docker.com?
    In this particular instance though, adolfintel appears to be the developer of Librespeed. The official documentation in that GitHub repo points to that docker image by adolfintel. Therefore, it counts as the official docker image in my book. Source: over 3 years ago

  • AWS us-east-1 outage: How Ably’s multi-region architecture held up
    During this week’s AWS us-east-1 outage, Ably maintained full service continuity with no customer impact. This was our multi-region architecture working exactly as designed; error rates were negligibly low and unchanged throughout. Any additional round trip latency was limited to 12ms, which is below the typical variance in any client-to-endpoint connection, and well below our 40–50ms global median; this is... - Source: dev.to / 10 months ago

  • Curiosity: Using Ably.io Realtime Messaging as a Lightweight Database
    Ably offers various solutions for developers, with their most popular being realtime messaging based on the pub/sub model. When you publish a message to a channel, all devices connected to that channel receive it instantly. - Source: dev.to / over 1 year ago
