Structure your architecture into organizations, projects, and subprojects to keep systems and diagrams organized and easy to navigate. Uxxu lets you organize diagrams into projects and subprojects, making it easier to manage large and complex architectures. Teams can maintain a shared object model between parent and child projects to keep architecture elements consistent, while still allowing projects to evolve independently. At the same time, object models can be separated between projects when needed, helping teams maintain clear boundaries between systems, domains, or products.

Key Objectives
Organization Structure
Shared Architecture Model
Project Boundaries
Separate Object Models
Projects can maintain independent object models when systems belong to different domains, products, or teams. This helps keep boundaries clear and prevents architecture models from becoming overly coupled.
Diagram Organization
Diagrams can be grouped within projects and subprojects, making it easier to navigate large architectures and find relevant views quickly.
Scalable Architecture Management
As systems grow, projects and subprojects help maintain a clear structure so teams can manage hundreds of diagrams and architecture elements without losing visibility.
Team Ownership
Different teams can manage their own projects while still contributing to a shared organizational architecture model.
Uxxu is a collaborative software architecture platform built around the C4 model. Teams use Uxxu to design, document, analyze, and evolve complex systems. Move beyond static architecture diagrams with connected views, dependency intelligence, technology lifecycle management, and real-time collaboration.
Start modeling your architecture today. Organize systems into projects, create C4 diagrams at multiple levels of detail, connect diagrams together, and explore architecture insights that help your team understand complexity and manage technical debt.
The C4 model is a lightweight approach to software architecture documentation created by Simon Brown. It describes architecture using four levels of diagrams: Context, Container, Component, and Code. Each level provides a different level of detail, allowing teams to communicate architecture clearly to different audiences. Uxxu is built around the C4 model and supports Context, Container, and Component diagrams out of the box.
Traditional diagram tools like Draw.io, Lucidchart, or Miro treat architecture diagrams as collections of shapes and arrows. Uxxu treats architecture as a structured model. Architecture elements such as systems, actors, applications, containers, components, and stores are defined once and reused across multiple diagrams. This means diagrams stay consistent, relationships are tracked, and the architecture can be analyzed to produce insights about complexity, dependencies, and technology usage.
Yes. Uxxu is designed for team collaboration. Organizations can invite collaborators as Viewers, Editors, or Administrators. Multiple users can work on diagrams and architecture elements simultaneously. Architecture is organized into organizations, projects, and subprojects so different teams can manage their own sections while still contributing to a shared organizational architecture model. This makes Uxxu suitable for both small engineering teams and large organizations managing multiple products and domains.
Uxxu is built to scale with architecture complexity. Large systems can be broken down into organizations, projects, and subprojects. Diagrams are connected together so teams can navigate from a high-level system context down to detailed container and component views. Architecture elements are shared across related projects to maintain consistency. Built-in analytics provide metrics such as architecture size, diagram density, and dependency concentration to help teams understand how their architecture is growing and where complexity is accumulating.
Technology lifecycle management in Uxxu allows teams to tag architecture elements with the technologies they use and assign each technology a lifecycle status: Future, Production, Deprecated, or Removed. This makes it possible to track which technologies are actively used, which are being phased out, and which are planned for future adoption. Teams can then generate reports showing the distribution of technology lifecycle stages across the entire architecture, helping them prioritize modernization efforts and manage technical debt proactively.
Yes. Every organization in Uxxu includes a free plan that supports up to 100 architecture items. This is enough to model a meaningful architecture and explore all the core features of the platform before committing to a paid plan. Architecture items include systems, actors, applications, containers, components, stores, and groups. Diagrams are not counted toward the item limit. Paid plans unlock higher item limits, advanced analytics, real-time collaboration features, and priority support.
