    Since it's a header-only library, with a lot of templates, only the used code will be compiled. So yes, this is tiny. Tinier than Unity, CryEngine, Unreal Engine, or other huge frameworks of that kind.

      A comparison to those engines is a bit much isn’t it? It’s not like it provides comparable features.
      • linkdd 5y ago
        IIRC, all those engines provide an ECS that could be compared to entt. Also, there is Hazel[0] which is based on entt and is the subject of an amazing youtube series[1]. IMHO, tinier means less features, at that point what could be considered comparable?

          To be comparable in size we should look at what they do. The three game engines originally mentioned have everything from physics to an entire visual IDE. A comparable smaller project is Godot not entt. A comparable ECS implementation is what you’re after. Is entt tiny in comparison to similar projects.
