About:
EnTT is a header-only, fast and modern C++ entity-component system (ECS) designed for performance and ease of use. It leverages compile-time mechanisms to minimize runtime overhead, making it ideal for game development and other performance-critical applications requiring data-oriented design.

Key Features:

High performance with minimal memory footprint
Header-only library, no compilation required
Modern C++11/14/17/20 support with intuitive API
Stable and well-tested in production environments

Use Cases:

Game development for managing game entities and components
High-performance simulation software
Architecting complex systems using data-oriented design

Alternatives:

EntityX – EnTT is generally faster and more memory-efficient due to its sparse set implementation.
OpenECS – EnTT offers a more modern C++ API and better compiler compatibility.
