Spec score 8.8 #12 of 92 in Game Engine Software

What it is

jMonkeyEngine is a free, open-source Java game engine for developers. It targets Windows, macOS, Linux, Android, and iOS, with mobile export and multiplayer foundations. Rendering includes a GLES 3.0 backend and direct OpenGL support from versions 3.2 through 4.5. Java 11 through Java 21, Gradle builds, JVM tooling, and direct Java-library use are listed. Networking foundations cover TCP, UDP, RPC, and synchronization patterns. Physics options include rigid-body, soft-body, and vehicle simulation through Bullet, Box2D, or Jolt Physics integration. Graphics features include PBR, custom materials and shaders, bloom, FXAA, SSAO, and tone mapping. A glTF workflow is described for moving Blender materials, lighting choices, and scene setup. The BSD 3-Clause License includes no runtime fees, royalties, splash-screen requirement, or requirement to mention the engine. Setup uses an initializer, NetBeans-based SDK, or direct Java-library configuration. SDK integrations are maintained separately and may lag engine features.
