Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

What's the story behind your product?

Belly Clock's answer:

As a Muslim, I fast a few times throughout the year. However, I've never come across an app that caters to Islamic fasting or more especially, tracks the different times of the Islamic Calendar when a person should fast. I wanted something comprehensive for myself with the hope of helping other Muslims enjoy their journey too and encourage them to fast beyond the obligatory days. Why not throw in other fasting methods that most apps and websites don't cover?

Which are the primary technologies used for building your product?

Belly Clock's answer:
