WindUI is an open-source Luau UI library for Roblox script hubs. It gives you a fully-featured window system, a set of interactive elements, multiple built-in themes, a config/flag system for persisting state, and a key system for access control — everything a modern script hub UI needs, packaged as a single loadstring call.
WindUI is currently in Beta. This project is still under active development. Bugs, issues, and unstable features may occur. Report any problems you encounter on GitHub or in the Discord server.
