Well that's the backend framework for the forums. I'm more interested for the frontend framework (AngularJS,Bootstrat) that was used. More specificly Terraria website. But i'm guessing the forum is using the same frontend framework as the official websiteIf you mean the forums, software called XenForo is used.
As far as I know, the game website was developed inhouse by Skiphs, a (now ex) developer of Terraria. It doesn't use the same software as the forum. I do not know what he used to develop it, but as it's a pretty simple static website I doubt there are many complicated web technologies behind it.Well that's the backend framework for the forums.
