The word progressive refers to its MVVM architecture (model-view-view model). Unlike the monolithic architectures, Vue-based applications can be easily adapted to your needs. You can scale it up or down, add new features and integrations with third party services.
In software development, time is money. Vue.js allows for a faster development, offering you high-performing, scalable solutions for less. The scalability also means that you can start small and build up whenever you want to do.
