KeystoneJS features and specs

  • GraphQL API
    KeystoneJS automatically generates a GraphQL API based on your schema, providing modern API capabilities and powerful querying options.

Possible disadvantages of KeystoneJS

  • Development Community
    While active, the development community is smaller compared to other popular frameworks, which might limit the availability of third-party plugins and resources.
  • Documentation
    Some users have reported gaps in the documentation, which can pose challenges when trying to implement advanced features or debug issues.
  • Performance Overhead
    Like many CMS solutions, there can be significant overhead, and performance might not match solutions built from scratch for high-performance demands.
  • Learning Curve
    Though easy to start with, mastering its full potential requires a deep understanding of GraphQL and Node.js, which might be a hurdle for some developers.
  • Limited Built-in Features
    KeystoneJS provides a basic set of features out of the box, meaning additional functionality may often need to be custom-developed, increasing development time.

Okular features and specs

  • Open Source
    Okular is an open-source software, which means the source code is freely available. Users can modify and distribute it according to their needs.

    The interface is highly customizable, enabling users to tweak the appearance and functionality to match their preferences.
  • Tabbed Browsing
    Okular supports tabbed browsing, allowing users to open multiple documents in a single window, enhancing multitasking.

Possible disadvantages of Okular

  • Limited Advanced PDF Editing
    While Okular provides basic annotation features, it lacks advanced PDF editing capabilities like modifying text and images within a PDF.
  • Learning Curve
    New users might find the extensive range of features and settings overwhelming, leading to a steeper learning curve compared to simpler document viewers.
  • Performance Issues
    Some users have reported performance issues when handling very large files, which can result in slower operation and responsiveness.
  • Dependency on KDE Libraries
    To get the best experience, Okular requires KDE libraries, which might not be ideal for users who prefer not to integrate KDE components into their system.
  • Mobile Support
    Okular does not have a dedicated app for mobile platforms like Android and iOS, limiting its usability on tablets and smartphones.

    Also, there are lots of exciting web frameworks that use Prisma as their default ORM layer (like RedwoodJS which is built by the founder of GitHub, Amplication which recently raised $6.6M in seed funding, Wasp (YC W21) or KeystoneJS) which should give you some more validation that Prisma is being used in a lot production applications :).
