I wonder if there is some server that can admin several Screenly OSE systems?

I wonder if there is some open source server that can admin several Screenly OSE systems? I know the Screenly commercial version already do that, but i suppose some open source alike Screenly servers are under development, been able to admin several Raspberries, maybe already are some around out there? I only found a old system but it is discontinued since a while, do anyone knows of “screenly-manager”:
