A high-performance, fully managed C# Entity Component System library focused on simplicity, reliability, and developer experience.
Friflo.Engine.ECS is a high-performance Entity Component System (ECS) library for C# that enables developers to build highly decoupled and efficient data-processing applications. It focuses on simplicity, reliability, and a smooth developer experience while avoiding unsafe code to prevent memory corruption. The library is designed for cross-platform use, supporting game engines like Unity and Godot, as well as web and desktop environments.
C# developers building high-performance applications, especially in game development (using Unity, Godot, or MonoGame) or data-intensive systems requiring efficient entity management and data processing.
Developers choose Friflo.Engine.ECS for its combination of top-tier performance, fully managed safety, and a clean, simple API. It is the only fully managed C# ECS that avoids unsafe code while matching the speed of C/C++/Rust alternatives, making it both reliable and highly efficient.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Fully implemented in managed C# with no unsafe code, preventing memory corruption and crashes, as emphasized in the README's reliability focus.
Achieves C/C++/Rust-like speed with continuous memory layouts and SIMD support, backed by benchmarks showing it outperforms many other C# ECS libraries.
Supports .NET Standard 2.1 to .NET 10, WASM, Unity, Godot, MonoGame, and Native AOT, enabling deployment across diverse environments with minimal changes.
Clean, type-safe API with minimal boilerplate, query generation to reduce code, and extensive documentation with examples for smooth onboarding.
Includes system performance monitoring for execution times, memory allocations, and entity counts, aiding in optimization and debugging without external tools.
As a newer library, it has a smaller community and fewer third-party tools compared to established ECS frameworks like Unity DOTS or Arch, which may limit resources and integrations.
While the API is simple, ECS itself represents a paradigm shift from OOP, so developers unfamiliar with ECS concepts might face a steeper learning curve despite good documentation.
The fully managed approach, while safe, could introduce slight performance overhead in edge cases compared to unmanaged alternatives, though benchmarks generally show top performance.
