Flecs – A fast entity component system for C and C++

Could this be used to implement an efficient backend server for an Unreal Engine game?

Doesn't Unreal have its own entity system yet?

It does and it is called Mass Entity.

(not a game dev, don't quote me :) )

Unless I'm mistaken, Unreal hasn't had an official blessed ECS system relying on other things: from just having regular objects to reading data from data tables.

They did introduce an ECS with (currently experimental) Mass Entity in Unreal 5: https://docs.unrealengine.com/5.0/en-US/mass-entity-in-unrea...

i dont think it's tied to any particular engine or renderer, because an ECS is merely a mechanism to organize data so that it can be accessed fast.

It could be yep. One of the things that makes it a good fit for this use case is that Flecs has a query language that supports things like graph traversal and joins. Combined with either the builtin REST API or some custom protocol you could use it as a realtime in-memory database (which is what I use it for).
