I know it’s very efficient and small (I believe it needs less than 80mib of ram with nothing else running) and that they leave out some of the basic commands like man to save space. Maybe they wrote more minimal versions of some coreutils?

RAM usage depends on what you run inside the container not on the image size. If the container runs a single small program it will use a small amount of RAM regardless of the image it’s based on.
