The modern game engine for Java developers.
Code-first. Flexible. Built for creators who want full control.
jMonkeyEngine 3.10 is now in beta! This release rewrites the platform backends from the ground up, improves iOS support, adds better compatibility and DPI handling, refreshes input support, improves lighting and PBR behavior, fixes shader issues, improves glTF support, and much more.

A featured project from the jMonkeyEngine community.
Rapid Escalation is a fast-paced incremental space arena game built around short, explosive battles, permanent upgrades, and exponential growth.
View projectA code-first Java engine with one rendering model, cross-platform targets, networking, audio, UI, assets, and room to build your own pipeline.
Write against one stable GLES 3.0 backend, powered by modern Vulkan, Metal, or DirectX through ANGLE for better portability and testability; or use OpenGL directly from 3.2 up to 4.5.
Coming soon
Build Java games for Windows, macOS, Linux, Android, and iOS, targeting modern x86_64 and ARM64 machines with one engine architecture.
Bring the Java ecosystem into your game: Java 11 through Java 21, Gradle builds, JVM tooling, and the huge world of Java libraries you can use directly in your app.
Real-time multiplayer foundations with TCP, UDP, RPC, synchronization patterns, and room to choose the network model your game needs.
Rigid body, soft body, and vehicle simulation with Bullet, Box2D, or Jolt Physics integration.
Build HUDs, menus, debug panels, and editor interfaces directly inside the engine, using built-in GUI support or community UI toolkits.
Use built-in PBR, custom materials and shaders, plus post-processing effects like bloom, FXAA, SSAO, and tone mapping. Customize the pipeline when your game needs its own look.
Cross-platform positional audio for games and simulations, with listener-relative sound, attenuation, and spatial scene integration.
Heightmap terrain, paged worlds, voxel environments, iso-surface techniques, and procedural generation can all be built on top of the scene graph.
Built-in particle emitters cover common effects, while the engine remains open enough for custom particles and community extensions.
The engine does not force a single development architecture. Use scene graph controls, app states, ECS-style systems, custom frameworks, or your own hybrid stack.
jMonkeyEngine can be extended for VR and XR projects, with community toolkits covering headset interaction, hand input, and immersive application structure.
Use jME as a foundation for your app, editor, toolchain, or engine, with access to GLES and GL calls plus internals when special requirements need to bend the flow.
Import glTF assets with a workflow aimed at Blender parity, so materials, lighting choices, and scene setup transfer predictably into the engine.
More than 21 years of development and an international dedicated community have grown modules, libraries, plugins, examples, and community projects around a BSD-licensed core.
