Arch
A high-performance C# Archetype & Chunks Entity Component System (ECS) for game development and data-oriented programming.
What is Arch?
Arch is a high-performance Entity Component System (ECS) library written in C# that uses the Archetype & Chunks pattern. It is designed for game development and data-oriented programming, providing exceptional cache efficiency, fast iteration, and low memory allocation to handle massive worlds of entities and components.
Game developers and software engineers working on performance-critical applications in C#, especially those using or integrating with game engines like Unity, Godot, or MonoGame.
Developers choose Arch for its balance of simplicity and raw performance, offering a minimal API without hidden costs while competing with the speed of ECS libraries in lower-level languages like C++ and Rust.
