    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. ...

    Mach Engine

    Mach Engine

    Zig game engine & graphics toolkit

    ...The engine supports a broad set of target platforms — desktop OSes and in principle, future expansion — and tries to simplify the pain of dependency management and cross-compilation, making it easier to build and deploy across systems without complex toolchains. Mach’s philosophy emphasizes composability and modularity: rather than pushing a “big engine with everything included,” it gives developers the building blocks to create exactly what they need.
