    nunuStudio

    nunuStudio

    Web powered cross-platform 3D, WebXR game engine

    nunuStudio is an open-source editor + game development environment — a “studio” rather than just a library — designed to let developers create interactive 2D and 3D content through a user-friendly interface. It provides visual tools for scene editing, asset management, materials, and possibly scripting, aiming to reduce the friction of hand-coding every aspect from scratch. As an accessible entrypoint to game or interactive content creation, nunuStudio is well-suited for artists, designers, or developers who prefer a WYSIWYG (what you see is what you get) workflow instead of fully coding everything. Because it is open source, users can inspect, modify, or extend the system as needed — adding custom behaviors, plugins, or export options. It’s ideal for rapid prototyping, small games or interactive demos, or educational purposes: you can build scenes, tweak visuals, test interactivity without deep diving into all low-level rendering details.
