Share variables among builds on different machine

hi everyone, I need a tips for figure it out a good strategy to solve this problem: I have different builds of different projects that have to share simple common variables (int, float, strings). For exemple I need to modify a value on a machine and see that value change for everyone. All the builds run on machine under the same wi-fi network.

My initial thought was to explore the built-in network services on Unity but I think they are too advance for this situation and my knowledge is very poor about that.

Any thought about a possible strategy or good documentatio/tutorial to follow?
