BRUTAL

BRUTAL is a free open source C# framework for building games or custom game engines.

BRUTAL is a free, open source C# framework designed for making games or building custom game engines from the ground up. It features a custom interop layer for direct access to native APIs, along with libraries for mathematics, memory management, strings, collections, job scheduling, logging, and localization. Developers write their own stack and choose their own NuGet packages instead of relying on a preset editor, scene graph, or renderer. The framework includes bindings for Vulkan, OpenGL, GLFW, SDL, Dear ImGui, FMOD, RakNet, Jolt, and Box2D. It suits developers who want complete independence and low-level control over their tools, supporting Windows and Linux platforms with the .NET 10 SDK.
