In their own words
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.
Ren'Py
Ren'Py is a free visual novel engine for making interactive stories and life simulation games with words, images, and sounds. Its script language handles visual-novel writing, while Python can be used for more complex game logic. Default games include menus, automatic saves, rollback, predictive image loading, and mouse, keyboard, or gamepad controls. Creators can customize screens and styles using the screen language and Python. The launcher builds Windows, Mac, and Linux games from any of those desktop systems. Ren'Py also supports Android export and can package games for WebAssembly browsers, though web support is beta and lacks networking and multithreading. It targets Windows 10 or later, macOS 10.10 or later, Linux x86_64 or Arm, Android 5.0 or later, and iOS 11 or later. Building for iOS requires a Mac and Xcode, and that support remains a work in progress. The engine is free for commercial and non-commercial use; most is MIT-licensed, with some LGPL components whose terms distributors must meet.
