CraftStudio

[4] The successor to CraftStudio is Superpowers, a collaborative HTML5 game development environment,[5] which was fully released in July 2016.

[5] CraftStudio allows users to work collaboratively on projects in real-time to create voxel-based video games in both 2D and 3D, with assets stored in the cloud.

[1][7] The tool encompasses the entire video game development workflow, allowing users to manage models, animations, Lua scripts, and maps obtained from pre-made assets or created from scratch.

[1] Games can be published for Windows, macOS, Linux, or the web browser.

This toolkit became the Hytale Model Maker, and is used to create all of the items, NPCs, and animations in the game.
