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.

Possible disadvantages of Flexbox Froggy

  • No Customization
    Users can't modify the exercises or explore additional scenarios beyond what is provided, limiting opportunities for creative problem-solving.

    While interactive, the game provides minimal explanatory content or theory, which might not be sufficient for users who prefer detailed explanations of how Flexbox works.

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

  • My Journey into Open Source: First Contributions and Lessons Learned
    Then, I came across Cal.com, a fantastic open-source project for scheduling meetings and managing tasks (super useful for productivity!). I knew the basics of Git but wasn’t quite there with forking, merging branches, and all the intricate Git processes. After some YouTube tutorials, I started to get the hang of things. 😅. - Source: dev.to / 8 months ago

  • 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
