Hytale-Servers.org and Hytale-Servers.com and Hytale-Server.com are officially giving away FREE Sponsored Slots to a few lucky server owners who register on each of the two websites prior to Hytale's official release! Registration is easy, and only takes about 30 seconds! Don't miss out! 🥇
It is most likely that you're going to need to pay if you want to host a big server that's on 24/7.
Although you might be able to host a small lobby to let your friends join in. (Either that be intergrated in-game or some other program such as Hamachi)
But for now we don't have any official information on the matter so we'll just have to wait and see.
