Is netcode for gameobjects fully free? When unity relay says pay as your game grows does that mean I have to pay when a certain amount of players start playing or does it mean I have to pay when my game starts making money?
Unity cannot charge for NetCode because it is free under the MIT licence. However, they do charge when you go above a certain number of CCUs (concurrent users). According to this page, you get a certain number of CCUs for free but pay per CCU after that. I guess that’s the CPU cost. You also pay bandwidth cost for data leaving their server. Please note I’m not including the actual cost in this reply because it’s likely to change. Best refer to the official Unity page
