Out of the box there is no manager provided. The core ark server is a .exe that you run, and to configure the server you are changing 2 different txt files. There are 3rd party apps that make life a LOT easier (Ark server launcher and Ark server manager) these also handle restarts, updates, backups and the likes. I have hosted numerous servers using ark server manager, without it, it would be very difficult.
As you state, community members provided these two launchers, who knows how long it will be until we have an Atlas one
Thanks Cybinja, i checked the forum earlier but he hadn't replied. That doesnt look very promising
