    Some users may find the customization options within Close to be somewhat limited, which can be a drawback for businesses with highly specific needs.
  • Learning Curve
    Despite its overall ease of use, some features can have a steeper learning curve, potentially requiring additional time for new users to become fully proficient.
  • Mobile App Limitations
    The mobile application currently offers fewer functionalities compared to the desktop version, which can be restrictive for users who need to manage workflows on the go.

    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
