## What it is
OpenJFX is the open source mainline development project for JavaFX, a next-generation client application platform for building rich desktop, mobile, and embedded applications on the JVM. It provides a modern, fully featured UI toolkit licensed under GPL v2 with the Classpath exception, governed under the OpenJDK project.

## Use cases
- build rich desktop applications in Java
- develop cross-platform GUI apps on the JVM
- create JavaFX-based mobile or embedded clients
- contribute to the JavaFX platform source code
- build modern UI toolkits on top of JavaSE
- port JavaFX to new platforms or devices

## When to choose
- you are building rich client applications in Java or another JVM language
- you need a mature, fully featured UI toolkit with hardware-accelerated graphics
- you want to target desktop, mobile, and embedded systems from one codebase
- you need an open source, GPL-with-Classpath-exception licensed Java UI framework

## When to avoid
- you are building server-side or web-only applications with no rich client UI
- you need a pure web/HTML frontend rather than a native client toolkit
- you require a permissive license like MIT or Apache rather than GPL with Classpath exception
- you are not working on the JVM platform

## Facets
- artifact type: framework
- maturity: active
- function: ui-components, graphics, animation, gui, mobile-framework, desktop-framework
- domain: cross-platform, desktop-applications, mobile-development, web-development, graphics
- platform: cross-platform, jvm, windows, embedded
- tags: javafx, openjfx, java, client-toolkit, rich-client-applications, openjdk, desktop, mobile, linux, macos
