  • Instant Collaboration
    The platform supports real-time collaboration, enabling multiple developers to work on the same project simultaneously.
  • Pre-configured Environments
    It provides a variety of pre-configured templates for popular frameworks like React, Vue, and Angular, which saves time on setting up development environments.
  • Integrated Development

    Seamless integration with GitHub allows importing and exporting repositories, making it easier to manage version control and workflows.
  • Accessibility

Possible disadvantages of CodeSandbox

  • Performance Issues
    Some users experience lag and slower performance, particularly with larger projects, compared to local development environments.
  • Limited Customization
    While convenient, the pre-configured environments might limit advanced customization options available in local IDEs.
  • Dependency on Internet
    As an online platform, a stable internet connection is required to use CodeSandbox effectively, which could be a limitation in areas with poor connectivity.
  • Free Tier Limitations
    The free version comes with certain restrictions on resources and functionality, which might not be sufficient for larger or more complex projects.
  • Security Concerns
    Storing code in an online platform can raise security concerns, especially for sensitive or proprietary projects.
  • Learning Curve
    Despite its ease of use, developers new to online IDEs might face a learning curve in adapting from traditional, local development environments.

Cal.com features and specs

    Cal.com allows extensive customization to fit various branding and scheduling needs, which makes it adaptable for different types of users including businesses and individuals.

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.

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

  • Thankful for CodeSandbox
    I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / 2 months ago

    I have, it's called Visual Studio Code and I ditched my old native editor(s) for it. I'd even suggest that the fact that it's JS based has significantly changed the tech world because the editor itself will run in a browser so it's here https://godbolt.org/ , and here https://codesandbox.io, and here https://www.postman.com/, and here https://aws.amazon.com/pm/cloud9/ and 100s or 1000s of other sites. - Source: Hacker News / 4 months ago

    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
