Possible disadvantages of Cal.com

    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.

    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.

  • Initial Setup
    Setting up a Symfony project can be daunting, especially for developers who are new to the framework, due to the amount of configuration and dependencies needed.
  • Documentation Overload
    While extensive documentation is beneficial, the sheer volume can be overwhelming for new developers trying to find specific information quickly.
  • Dependency Management
    Symfony requires careful management of dependencies, and keeping track of updates and compatibility can be burdensome, especially in large projects.

The Most Popular PHP Frameworks to Use in 2021
The best way to interact with your databases is via the Doctrine ORM. Symfony uses data mappers to map objects to the database. This keeps your object model and the database schema separate, meaning that if you change a database column you don’t need to make many changes in your codebase.

    Then, I came across Cal.com, a fantastic open-source project for scheduling meetings and managing tasks (super useful for productivity!).

  • 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
