What is WorldKit?
WorldKit is a suite of advanced tools for creators and developers who want full control over how worlds are built, synchronized, and extended. It provides the runtime, pipelines, and adapters needed to create sophisticated, interoperable Web Wide Worlds.
In short: WorldKit is the power-user toolkit for building, orchestrating, and integrating worlds at any scale.

WorldOS
The modular, distributed runtime at the core of WorldKit
Inspired by ROS
WorldOS treats each world as a system of coordinated apps and services. Apps can be written in different languages, deployed across containers, and communicate through topic-based, event-driven messaging.
MQTT Message Bus
At its core, WorldOS uses an MQTT message bus for low-latency, pub/sub-style communication between world components, enabling flexible and scalable architectures.
WorldSync
Lightweight real-time synchronization for multiplayer experiences
Presence & Transform Sync
WorldSync delivers real-time presence and transform synchronization, enabling smooth collaborative interactions across devices.
MQTT over TCP/WebSocket
Built on MQTT over TCP/WebSocket for reliable, low-latency multiplayer state management across your worlds.
Creation Tools
Build worlds locally and export them into WebVerse-ready VEML
World Builder
A visual tool for constructing and editing worlds, allowing creators to design immersive environments with intuitive controls.
VEML Blender Plugin
Export your Blender scenes directly into WebVerse-ready VEML format, bridging professional 3D workflows with Web Wide Worlds.
