UxxU

Connected C4 Architecture Modeling

Create linked System Context, Container, Component, and Deployment diagrams that allow teams to navigate architecture from high-level overviews down to implementation details. Architecture elements are reusable across diagrams, ensuring consistency throughout the model.

Living Architecture Documentation

Replace static diagrams with a structured architecture model that evolves alongside the codebase. Changes to systems, containers, or dependencies automatically propagate across related diagrams and views.

Architecture Analytics & Dependency Intelligence

Analyze architecture complexity, dependency concentration, technology usage, and structural risks such as circular dependencies or single points of failure. Built-in metrics help teams understand and manage architectural growth over time.

Real-Time Collaboration

Collaborate with architects, developers, and stakeholders in a shared workspace with real-time editing, role-based access, and organization-wide visibility into architecture decisions.

AI & MCP Integration

Connect AI coding assistants and MCP-compatible tools like Claude Code, Codex, and OpenAI workflows directly to Uxxu. Generate C4 diagrams from specifications and keep architecture artifacts inside a centralized architecture platform.

Automatic C4 Generation from Code

The upcoming codeToC4 capability can generate context, container, and component diagrams directly from repositories, enabling architecture documentation to evolve with Git branches and releases.

Embeddable Architecture Diagrams

Embed live architecture diagrams into documentation platforms, blogs, internal wikis, Notion pages, and websites while maintaining a single source of truth.

Technology Lifecycle Tracking

Track technologies used across systems and classify them as Future, Production, Deprecated, or Removed to manage modernization and technical debt more effectively.

Organizational Architecture Management

Structure architecture into organizations, projects, and subprojects for large engineering teams and multi-domain systems.

Free Plan for Small Teams

Includes a free tier supporting up to 100 architecture items with no credit card required.

Software Architecture Documentation

Maintain clear, navigable architecture documentation that stays current as systems evolve.

Engineering Team Collaboration

Enable developers, architects, and stakeholders to work from a shared architectural source of truth.

C4 Model Adoption

Help teams implement the C4 model with structured Context, Container, Component, and Deployment diagrams.

Technical Onboarding

Accelerate onboarding by giving new engineers a navigable understanding of systems, dependencies, and workflows.
