โญ๏ธ Mark commented on our Reddit: โ€œI've been like a kid in the candy store as I'm building extensions on almost everything... Here are a few of my latest: * Added a button that will summarize the main question and give the "vibe" of the group's answers for questions posted on a financial advisor message board * Grabbing data from website tables and saving in a CSV file format * Add a button that finds and saves all phone call recordings (GoTo) that are more than seven minutes long (requires clicking into various areas) * Added a button on a financial graphing program that creates an email that summarizes the chart in plain language, and copies the summary to the clipboard My prompting has been very relaxed, but I've been happy with the generated tools. I'm sure my prompting will get more specific over time. I've not had too many ideas that were complete flops.โ€

โญ๏ธ Piknockyou left a 5-star review on the Chrome Web Store: โ€œAbsolutely brilliant extension. It worked like a charm in 1-shot to scrape comments and replies on MyDealz.โ€

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.
