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.

Cal.com features and specs

  • Customizable
    Cal.com allows extensive customization to fit various branding and scheduling needs, which makes it adaptable for different types of users including businesses and individuals.
  • Open-source
    Being an open-source platform, Cal.com provides the flexibility for developers to modify and extend the software as per their specific needs, fostering a collaborative development environment.
  • Integrations
    Cal.com offers a wide range of integrations with other software tools like Google Calendar, Microsoft Outlook, and Zoom, enhancing its functionality and making it easier to fit into existing workflows.
  • User-friendly Interface
    Cal.com has an intuitive and clean interface that makes it easy for users of all technical skill levels to set up and manage their scheduling.
  • Privacy-focused
    Cal.com emphasizes data privacy, ensuring user information is handled securely, which is crucial for users who need to comply with regulations like GDPR.

Possible disadvantages of Cal.com

  • Learning Curve
    Although it is highly customizable, the plethora of options and features may result in a steeper learning curve for new users who are not familiar with such scheduling tools.
  • Limited Free Version
    The free version of Cal.com comes with limitations that may not be sufficient for growing businesses or advanced users who require more comprehensive features.
  • Dependency on Integrations
    Cal.com's effectiveness heavily depends on its integrations. Without these integrations, some users might find the tool less useful or incomplete, especially if their primary tools are not supported.
  • Support
    While open-source has many benefits, it may also mean that immediate, personalized support could be limited compared to fully commercial solutions. This might pose a challenge for users needing quick resolutions.
  • Performance
    As an open-source platform, the performance might vary depending on how it is hosted and managed. Suboptimal configurations could lead to slower performance or downtimes.

Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling โ€” you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own โ€” Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning. If you're leaving for a narrower reason, match it precisely: SimplyBook.me for...

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • 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. Source: over 3 years ago
  • 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

  • "You Wouldnโ€™t Steal a DIV": How I Built My Portfolio
    Then for the component library, I was really into coss ui. I stumbled upon it randomly one day and loved it so much. My Nathan's AI project already had a UI heavily inspired by cal.com: send button, message suggestions... So when I saw they had a shadcn/ui library with that kind of style, it was perfect for what I needed. - Source: dev.to / 4 months ago
  • AI Almost Sold Me a Subscription I Didn't Need
    I keep coming back to what would have happened if I didn't have a strong technical understanding of how calendar technology works โ€” the difference between local and cloud calendars, what an ICS feed is, why enterprise auth blocks third-party integrations. If this was many years ago before I gained all this experience, I would have stopped at the first confident answer from my search tool, installed one of those... - Source: dev.to / 5 months ago
