Project mention: Using Jolt with flecs & Dear ImGui: Game Physics Introspection | dev.to | 2024-04-17EnTT is a popular alternative to flecs for C++, which has different performance/memory characteristics.

Project mention: Zero-k: A libre sci-fi RTS game, with an economy based on metal and energy | news.ycombinator.com | 2023-11-19Seems the support would be a realistic feature, though, because it's based on https://springrts.com/ that does support MacOS X.
