In their own words
Bevy
Bevy is a free, open-source game engine built in Rust for 2D and 3D games, visualizations, interfaces, and other graphical applications. It uses a custom Entity Component System, with components represented as Rust structs and systems as Rust functions. The engine includes 2D and 3D rendering, a composable render graph, skeletal and morph-target animation, scene loading, hot reloading, UI, and audio playback. Its 2D renderer supports sprites, texture atlases, cameras, materials, custom shaders, and render pipelines. The 3D renderer includes lights, shadows, meshes, materials, cameras, and glTF loading. The ECS-driven UI framework uses flex-box layout and can be composed in code or scenes. Scene changes can update running applications; hot reloading currently covers scenes, textures, and meshes. Bevy targets Windows, macOS, Linux, web, iOS, and Android, and is available through crates.io with cargo add bevy. Users choose MIT or Apache 2.0 licensing, with no license fees or sales cuts. It remains in development, with possible missing features, sparse documentation, and breaking API changes about every three months.
jMonkeyEngine
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.
