Possible disadvantages

Smaller Community
Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
Learning Curve
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.
Rapidly Evolving
Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.
