Possible disadvantages of Cal.com

  • 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.

    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.

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

  • "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

  • Alternatives to cron jobs
    I did end up going with AWS EventBridge to trigger the events, it was not as bad to configure as it seemed at first, but still I am surprised that there isn't a simpler solution. I did find https://posthook.io/ but that actually seemed even more complex than EventBridge. Source: over 4 years ago
