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.

Jekyll features and specs

  • Speed and Performance
    Jekyll generates static websites, which means they load faster compared to dynamic websites. No database queries are required, reducing server overhead and improving performance.
  • Security
    Static sites have a smaller attack surface compared to dynamic sites because they don't rely on databases or server-side code. This means fewer vectors for potential compromises.
  • Simplicity
    Jekyll setups are relatively straightforward, especially if you are comfortable writing in Markdown and HTML. This can make it easier to manage and maintain your website.
  • Integration with GitHub Pages
    Jekyll is designed to work seamlessly with GitHub Pages, allowing you to host your website for free with automatic deployment directly from your GitHub repository.
  • Customizability
    Jekyll allows for extensive customization through its support for plugins, themes, and templates. This can be helpful to create a unique look and functionality for your website.

Possible disadvantages of Jekyll

  • Learning Curve
    While Jekyll is simpler than some other static site generators, it does require some familiarity with the command line, version control (Git), and YAML configuration.
  • Build Time
    For large websites, the build times can become lengthy, which can slow down the development process, especially if you are making frequent updates.
  • Lack of Real-time Content Updates
    Since Jekyll generates static sites, real-time content updates (e.g., comments, dynamic forms) aren't natively supported and require third-party services or additional tooling.
  • Dependence on Ruby
    Jekyll is built with Ruby, so you will need to have Ruby installed and occasionally deal with Ruby-specific issues. This might be a drawback for developers who are not familiar with the Ruby ecosystem.
  • Limited Built-in Functionality
    While Jekyll is very flexible, it doesn’t have built-in support for many features out of the box, which might require you to manually implement or rely on plugins.

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

10 static site generators to watch in 2021
Perhaps most conveniently described as Jekyll implemented with JavaScript rather than Ruby, Eleventy has now moved beyond that while retaining a clear and simple on-ramp, and only shipping to the browser what you tell it too. As with Jekyll and Hugo, no JavaScript frameworks are auto-baked in.

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago

  • Building PicoSSG: 'Just Enough Code'
    The static site generator (SSG) landscape is crowded with feature-rich but increasingly complex solutions.
