You are a Java developer who wants to write 3D games that run on Windows, Mac, Linux, the web, and Android platform? Then you have come to the right place. The jMonkeyEngine framework (jME) is a high-performance, 3D scenegraph-based graphics API with state-of-the-art features.

The jMonkeyEngine 3 is a bunch of JAR files that you place on the Java classpath. The software is written in Java and uses LWJGL for OpenGL access. The jMonkeyEngine open-source community releases these libraries under the BSD license, which makes them free to use in any way that you see fit – be it hobby, educational, or commercial.

The third release of jMonkeyEngine is now in Beta. Still tied up with jME2? Please read our jME2 or jME3 choice rationale and jME2 vs jME3 feature comparison and start porting to jME3.

The jMonkeyEngine3 SDK is a preconfigured Software Development Kit, tailor-made for Java game developers. The SDK combines all jME3 libraries and some unique development tools that make your life easier when writing Java code and managing projects. The SDK includes project and file wizards, an advanced code editor, Asset Pack management, file converters, scene viewer and composer, code palette, terrain editor, and more.

Before installing, check the license, features, and requirements. Then choose one of these options:

	Recommended	Optional	Optional
You want to…	Get started with jMonkeyEngine	Use jMonkeyEngine in another IDE	Build custom engine from sources
Then download…	jMonkeyEngine SDK	Binaries	Sources (Subversion)
You receive…	Sources, binaries, javadoc, SDK	Latest nightly binary build, sources, javadoc.	Sources

(*) The SDK creates Ant-based projects that any Java IDE can import. We recommend users of other IDEs to also download the jMonkeyEngine SDK and choose "File→Import Project→External Project Assets" to create a codeless project for managing assets only. This way you can code in the IDE of your choice, and use the SDK to convert your models to .j3o format.

After downloading and installing, bookmark the jME Documentation page and start writing your first game!
