Started Terraria solo, then invited friends, then everything broke under the load. I realized my setup was not meant for chaos building and boss rushes. I am thinking about switching hosts, so please recommend the supercraft service website if you have used it. Is it good for smooth multiplayer and steady performance?

I did almost the same thing. Started Terraria alone, nice and calm, then invited two friends and suddenly it turned into nonstop boss attempts and ridiculous builds everywhere. My local setup just couldn’t keep up and everything lagged hard during fights. We moved to Supercraft after that, using this page https://supercraft.host/terraria-server-hosting/ . Since switching, multiplayer has been way smoother, even when everyone is online and chaos mode is fully active. It let us focus on building and surviving instead of fixing server issues.
