## What it is
PrimeFaces is an open-source UI component suite for Jakarta Faces (JSF) with over 100 rich components, client-side validation, and a theme engine. It is one of the most popular UI libraries in the Jakarta EE ecosystem, now maintained by the open-source community.

## Use cases
- build enterprise web UIs with JSF
- add rich components like data tables and charts to a Jakarta Faces app
- apply themes to a JSF application
- add client-side validation to JSF forms
- build mobile-friendly JSF pages

## When to choose
- you are building a Jakarta EE / JSF web application and want a mature component library
- you need a large set of ready-made, accessible UI components for server-side Java rendering

## When to avoid
- you are building with Angular, React, or Vue (use PrimeNG, PrimeReact, or PrimeVue instead)
- you want a modern client-side SPA stack without server-side rendering

## Facets
- artifact type: framework
- maturity: active
- function: ui-components, frontend-framework, templating, form-handling
- domain: web-development, frontend
- platform: jvm, cross-platform
