Many web server UI solutions are based upon Jakarta (Java) Server Faces ("JSF") which is a hybrid approach to supplying dynamic content to be displayed in a static web browser (see ).

For applications developed for JSF, it has been difficult to keep up with the changing landscape of client side JavaScript frameworks and HTML changes. PrimeFaces is a commercial solution that runs on most Java web server engines, including Apache Tomcat (see ).

PrimeFaces insulates the developer from worrying about what the latest flavor-of-the-month is for UI frameworks. Instead of worrying whether React, Angular, Vue.js, or some other solution will become dominant in the future, you can focus on building quality solutions (see ).
