FXGL is a Java/JavaFX/Kotlin game development framework (engine) built on top of JavaFX, offering a high-level entity-component API for 2D games with experimental 3D support. It runs out of the box on desktop, Android, iOS, and web, and games can be packaged into a single executable jar or native image.

Use cases

• build a 2D platformer or side-scroller in Java
• make an arcade or RPG game with JavaFX
• prototype a game idea quickly without engine setup
• teach game development in a university course
• build a business app with complex UI animations
• create a cross-platform game that runs on Android and iOS

When to choose

• you want a JVM-based 2D game engine with no installation or setup
• you already know JavaFX and want a superset API
• you need hobby, academic, or commercial 2D games packaged as a single jar
• you want fast prototyping with a simple, clean, high-level API

When to avoid

• you need production-grade 3D game development
• you want the largest ecosystem and asset store of Unity/Unreal
• you need maximum runtime performance for AAA-style games
• you are not working on the JVM
