Web Wide Worlds
Web Wide Worlds is an open, modular framework for building and exploring interoperable digital worlds. Itβs designed to empower creators, developers, and communities with tools that scale from personal sandboxes to planet-sized simulations.
From initial concept to live deployment, Web Wide Worlds streamlines the development process with intuitive tools, powerful APIs, and seamless integration between components.

Technology Stack
An open and modular architecture for building scalable digital worlds
π₯οΈ Scene Viewer
The rendering interface through which users access virtual environments. World Browsers, such as WebVerse, are software applications at the Scene Viewer layer.
π World Definition Layer
Defines the structure and behavior of a world through declarative markup (using VEML) and modular scripting (using JavaScript) components.
π Networking Layer
Enables synchronized presence and interaction across clients using open protocols and flexible multiplayer architectures (using protocols like WorldSync and Mirror Networking).
π§ Tooling & APIs
Provides extensibility and developer-facing interfaces for rapid prototyping to studio-scale integration. The ecosystem includes WorldOS, a NodeJS-based scaffold for runtime tools. The entire system is designed to be modular and non-prescriptive, allowing developers to choose their preferred tools and integration patterns.
π Publishing Layer
Governs how worlds are distributed and hosted with flexible ownership models and scalable distribution options.
