Possible disadvantages of CodePen

    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.

ReadEra mentions (1)

  • A few smaller things to celebrate
    I can answer question 1. To read downloaded fanfiction, or any other pdf/epub, you need a reader app. I personaly use the free version of ReadEra because it's the best I've found in terms of range of file formats, general functionality, and ease of use. I like it enough that I plan to spring the $10 for the paid version eventually. Source: about 3 years ago
