A Modern Cross-Platform Low-Level 3D Graphics Library and Rendering Framework

Diligent Engine is a lightweight, high-performance graphics API abstraction layer and rendering framework for cross-platform development. It leverages the power of modern graphics APIs such as Direct3D12, Vulkan, Metal, and WebGPU, while also maintaining robust support for legacy platforms through Direct3D11, OpenGL, OpenGLES, and WebGL. Providing a consistent front-end API, Diligent Engine uses HLSL as its universal shading language and also supports platform-specific shader formats (GLSL, MSL, DirectX bytecode, SPIR-V) for optimized performance. Ideal for game engines, interactive simulations, and 3D visualization applications, Diligent Engine is open-source and distributed under the permissive Apache 2.0 license.

¹ Vulkan API is not natively supported on MacOS, iOS and tvOS platforms and requires a Vulkan portability implementation such as MoltenVK or gfx-portability.

² Available under commercial license - please contact us for details.

³ Requires a native implementation of WebGPU, Dawn is recommended.
