## What it is
KlayGE is a cross-platform, open-source 3D game engine with a plugin-based architecture, developed in C++ since 2003. It aims to bring cutting-edge graphics technology to game development, testing, and porting across desktop and mobile platforms.

## Use cases
- build a cross-platform 3D game
- develop a game engine with cutting-edge graphics technology
- port a game to Windows, macOS, Linux, Android, and iOS
- prototype 3D rendering techniques with a plugin-based engine
- learn how a full open-source game engine is architected

## When to choose
- you need a free, open-source C++ game engine with permissive deployment across desktop and mobile
- you want a plugin-based architecture to swap rendering or audio backends
- you are comfortable with GPL 2.0 licensing for your project
- you want to study or extend a mature engine with modern graphics APIs like D3D12 and OpenGL

## When to avoid
- your project cannot be released under GPL 2.0
- you need a commercial license or proprietary game development
- you prefer engines with large asset stores and extensive tutorials like Unity or Unreal
- you need official console platform support

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, graphics
- domain: graphics, cross-platform
- platform: windows, cpp, python
- tags: 3d-engine, plugin-based-architecture, opengl, d3d12, openal, gpl-2.0, game-development, macos, linux, android, ios
