Rostar is an open source command-line tool that unpacks/packs Roblox rbxl/rbxlx places into model files and .lua scripts in the filesystem, for use with Rojo.

Useful both to developers that prefer Roblox Studio, but also to Rojo users that would like a fully managed workflow without a hassle.

Developing Rostar was a great exercise in making a CLI with Node, file management, serialization, and graph traversal algorithms.

Originally made as a commission, Rostar has been open sourced and publicized for anybody that finds it useful.
