Castle Game Engine

A free, open-source, cross-platform framework for building 2D and 3D games and interactive applications, featuring a powerful visual editor and support for open standards such as glTF, X3D, and IFC, enabling deployment across desktop, mobile, console, and web. It addresses multi-platform development challenges by delivering a fast, clean codebase in a modern Object Pascal language, a feature-rich scene graph with 3D and 2D assets, physics, lighting, shaders, animation, and UI components, plus tooling and integrations with popular IDEs, Blender workflows, and asset repositories, along with extensive tutorials and release-ready documentation, making it ideal for developers, hobbyists, educators, indie studios, and teams creating prototypes, games, simulations, or interactive experiences.

Castle Game Engine can be found in Game Development & Asset Creation categories.
