License for more then a 25 nodes

Hi,

I am completely confused about licensing and ChefServer. From this page, I do not understand what is the price for ChefServer https://www.chef.io/pricing/

In general, my plan is to use ChefServer Standalone and have more than 25 nodes.
https://docs.chef.io/install_server.html#standalone

Do I need to buy a license somewhere? Is there any option to run ChefServer without paying for more than 25 nodes.

Thanks
Milos

Run an older version of the Chef Server that doesn't require a license for more than 25 nodes is the best answer I know of; the 12.19 version should work just fine.
