Entitas is a fast Entity Component System (ECS) framework built specifically for C# and Unity, optimized for garbage-collected environments. It includes an optional code generator and Unity visual debugging integration, and also works in pure C# standalone projects.

Use cases

• build a Unity game with an ECS architecture
• structure game logic with entity component system in C#
• reduce boilerplate in Unity game code with code generation
• debug entity systems visually inside the Unity editor
• use an ECS framework in a pure C# project without Unity
• write testable game logic with TDD

When to choose

• you are building a C# or Unity game and want a battle-tested, popular ECS
• you need a garbage-collector-friendly ECS with strong performance
• you want visual debugging of entities and systems in Unity
• you want an ECS that works outside Unity in plain C#

When to avoid

• you are not using C# or Unity
• you prefer a full game engine with built-in ECS rather than a framework
• you need a framework with frequent recent updates and active maintenance
