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.

Node.js on App Engine features and specs

  • Scalability
    App Engine provides automatic scaling, which means your Node.js application can handle increased traffic by scaling up and scales down when the traffic decreases.
  • Fully Managed
    App Engine manages the infrastructure for you, including server configuration and management, allowing developers to focus on code rather than infrastructure.
  • Integrated Google Cloud Services
    Node.js on App Engine can easily integrate with other Google Cloud services like Cloud Datastore, Cloud SQL, and more, fostering rich and scalable application development.
  • Built-in Security Features
    App Engine provides built-in security features to protect your Node.js application including Identity and Access Management (IAM) and integration with Google’s security infrastructure.
  • Cost Efficiency
    The pay-per-use model ensures that you only pay for what you use, which can be cost-effective for applications with variable workloads.

Possible disadvantages of Node.js on App Engine

  • Cold Start Latency
    Like many serverless environments, Node.js applications on App Engine might experience latency due to cold starts, especially after periods of inactivity.
  • Vendor Lock-In
    Deploying on App Engine might lead to a certain level of dependency on Google Cloud’s ecosystem, making it challenging to migrate to another cloud provider without significant changes.
  • Limited Customization
    Being a fully managed service, there are limits to how much you can customize the runtime environment compared to traditional server instances.
  • Complex Pricing Model
    Understanding App Engine's pricing model can be complex, which could make cost estimation difficult, particularly without a clear forecast of usage patterns.
  • Resource Constraints
    Given that App Engine standard environment has specific resource constraints and quotas, this might not be suitable for applications with high memory or CPU demands.

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 / 7 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
