PrimeFaces is an open-source user interface component library for JavaServer Faces (JSF). It provides a large collection of reusable UI components that simplify the development of web-based enterprise applications built on the Java platform. The framework extends standard JSF capabilities by offering advanced components such as data tables, charts, dialogs, forms, file uploads, dashboards, and theming support. It integrates into existing Java EE and Jakarta EE environments and works within standard JSF lifecycle and configuration mechanisms. PrimeFaces is distributed as a software library that developers include in their Java web applications. In addition to the open-source edition, commercial editions and support services are available, providing extended features, long-term support, and professional assistance. The PrimeFaces ecosystem also includes related UI libraries targeting other frontend technologies, forming a broader component suite for different development stacks.
