Flecs
A fast and lightweight Entity Component System (ECS) for building games and simulations with millions of entities in C and C++.
What is Flecs?
Flecs is a fast and lightweight Entity Component System (ECS) framework for C and C++ that enables developers to build scalable games and simulations with millions of entities. It organizes code and data using entities, components, and systems to create complex, extensible applications efficiently. The framework solves performance and scalability challenges in game development by optimizing data layout and parallel execution.
Game developers and simulation engineers working in C or C++ who need a high-performance, portable ECS for building large-scale, data-oriented applications. It's particularly suited for projects requiring efficient multicore utilization and complex entity relationships.
Developers choose Flecs for its combination of speed, portability, and modern features like full entity relationship support and integrated reflection. Its zero-dependency design, cache-friendly storage, and lockless scheduler offer a unique blend of performance and simplicity compared to other ECS libraries.
