  • Performance Issues
    Users have reported that the software can be slow or laggy, especially with complex diagrams or longer usage periods.

  • Limited Online Resources
    There are fewer tutorials, plugins, and extensions available compared to more popular commercial alternatives.
  • No Cloud Storage
    The software does not offer built-in cloud storage or synchronization options, which can be a drawback for users needing secure storage solutions.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

  • Uizard: Figma alternative with low learning curve
    I am a software developer, so doing UX is never my strength. From time to time though, I would resort to using the open source tool Pencil (https://pencil.evolus.vn/) to get a low fidelity mock-up. Lately I've been encountering bugs where images would come out broken when I re-open my wireframe in Pencil. Frustrated of the issue on Pencil, I tried out uizard yesterday, and have been really happy with it. It's... - Source: Hacker News / over 3 years ago
  • Quick UI-design tool for mockups?
    Thanks for your replies. I checked some of them out, but I found one on my own that fits me perfectly: Pencil. Source: over 3 years ago
  • Best practice to draw/describe UIs in plain text?
    I wouldn't use text to illustrate a GUI. We use Pencil with the crayon-styled stencils to make quick mockups. The crayon styling makes it clear that they're just mockups so people don't poke at the style aspects of the design. We've gotten great feedback from our clients that these are effective illustrations too. Source: almost 4 years ago
  • Simple tool for network documentation?
    I use MS Visio at work and Pencil (free) at home. Source: about 4 years ago
  • A blog web design with Inkscape, what do you think about it?
    Thank you ! Of the ones I have tested, the only one that really works is Pencil, unfortunately, it lacks a lot of functionalities, and it is still far from being as practical as Figma, adobe xd etc. I think Inkscape is much more practical and powerful, but maybe it's just because I'm used to it :).
