Architecture knowledge is fragmented

Most software teams document architecture using a mix of diagrams, documents, and wikis.

Over time this creates problems:

  • Architecture diagrams that are not linked together
  • Documentation that quickly becomes outdated
  • Teams working in isolation
  • Difficult onboarding for new engineers
  • Limited visibility into system dependencies

Architecture knowledge becomes scattered across tools and teams, creating silos and making it harder to understand how the system actually works.

Uxxu keeps your architecture connected

Instead of isolated diagrams, Uxxu creates a living architecture model where everything is linked.

With Uxxu you can:

  • Create C4 diagrams and deployment diagrams
  • Organize architecture into projects and organizations
  • Define systems, actors, applications, stores, and domain objects
  • Link diagrams together and drill down into deeper architecture levels
  • Attach documentation and technology information
  • Annotate relationships between architecture elements

Your architecture becomes navigable, structured, and shared across teams.

The C4 Model for Software Architecture

The C4 model is a simple and structured way to describe software architecture using a small set of diagrams that show different levels of detail. It helps teams understand systems from a high-level overview down to the individual components that make them work. Uxxu supports the full C4 model, allowing you to navigate architecture from the big picture to the technical implementation.Here are the diagrams that UxxU can help you with.

1
C4 context diagram showing a system and its interactions with users and external systems

Context Diagram

Shows the system from a high-level perspective and how it interacts with users and external systems. It helps stakeholders understand what the system does and how it fits into the larger environment.

2
C4 container diagram showing applications, services, and databases inside a system

Container Diagram

Zooms into the system and shows the main applications or services such as web apps, APIs, and databases. It explains how the system is structured internally and how its main parts communicate.

3
C4 component diagram illustrating internal modules and components within an application

Component Diagram

Provides a deeper view inside a container, showing the main components or modules that implement the functionality. It helps developers understand how the code is organized.

4
C4 deployment diagram showing infrastructure, servers, and runtime environments

Deployment Diagram

Shows how the system is deployed across infrastructure such as servers, containers, and cloud services, helping teams understand how the software runs in production.

How UxxU Works?

Organise
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.
Organise
Model
Create context, container, and component diagrams to represent your system architecture at multiple levels of detail. Uxxu follows the C4 approach, allowing teams to move from a high-level system view down to detailed application and component structures. Define architecture elements such as actors, systems, applications, containers, components, stores, and groups, and organize them clearly within diagrams. Workflows and interactions between elements can be modeled to show how systems communicate and how data flows through the architecture. By modeling architecture in a structured way, teams can build diagrams that are clear, consistent, and easier to maintain as systems evolve.
Architecture Model
Connect
Uxxu diagrams are interconnected, allowing teams to navigate architecture from high-level system views down to detailed internal structures. Starting from a context diagram, you can drill down into container and component diagrams by creating subdiagrams that explain how systems work internally. Each level reveals more detail while remaining connected to the overall architecture. This navigation works similarly to Google Maps: begin with a broad view of your system and progressively zoom into deeper layers to explore services, components, and workflows.
Connected Architecture Diagrams
Collaborate
Uxxu enables teams to collaborate on architecture in a shared environment. Organizations can invite collaborators as viewers, editors, or administrators to participate in building and maintaining architecture models. Teams can work together to define systems, diagrams, and workflows while sharing a common understanding of how the architecture evolves. Real-time collaboration allows multiple teams and groups to design and update architecture diagrams together, making Uxxu ideal for organizations where architecture knowledge must be shared across many contributors.
Collaborate on architecture
Analyze
Uxxu transforms architecture diagrams into measurable insights that help teams understand the structure, complexity, and evolution of their systems. Because architecture elements are modeled as structured data, Uxxu can automatically generate metrics about architecture size, diagrams, dependencies, and technology usage. These insights help architects identify complexity, understand system relationships, and detect potential risks as the architecture evolves.
