About Uxxu

Uxxu helps teams model, understand, and evolve their software architecture. We believe architecture should be connected, collaborative, and measurable.

Our Story

Modern software systems are becoming increasingly complex. Architecture knowledge is often fragmented across diagrams, documents, and teams, making it difficult to understand how systems truly work together.

Uxxu was created to solve this problem. Instead of disconnected diagrams, Uxxu provides a collaborative platform where teams can model architecture, connect diagrams, and explore systems from high-level context down to detailed components.

Goal

Uxxu transforms architecture diagrams into a living architecture model.

Teams can explore systems, understand dependencies, and keep architecture documentation synchronized with the evolution of their software.

Founder

Guillermo Quiros is a software architect and entrepreneur with more than 20 years of experience building large-scale platforms and leading engineering teams.

During his career he has led cross-functional teams of up to 40 engineers and delivered complex cloud-native and SaaS platforms used by companies around the world.

Guillermo founded Uxxu to help engineering teams better understand and manage the architecture of their systems through connected diagrams, collaboration, and architecture analytics.

Our Vision

Architecture should not live in static diagrams or outdated documentation. It should be something teams can explore, analyze, and evolve together.

Our Mission

Uxxu is building the next generation of tools for software architecture — where diagrams are connected, knowledge is shared across teams, and architecture becomes measurable and actionable.

How Uxxu Works

Model Architecture

Define your systems, containers, components, and actors using the C4 model. Uxxu guides you through each level of abstraction, from the high-level system context down to detailed container and component views.

Connect Diagrams

Link related diagrams together so your team can navigate from a system overview into detailed service views without losing context. Architecture becomes explorable rather than a collection of disconnected files.

Analyze and Evolve

Use built-in analytics to understand architecture complexity, track technology lifecycle status, and identify where dependencies are concentrated. Keep architecture documentation aligned with how the system actually evolves.

Why the C4 Model

The C4 model, created by Simon Brown, is a lightweight and widely adopted approach to software architecture documentation. It describes software using four levels of abstraction: Context, Container, Component, and Code. Each level provides a different perspective, making it easy to communicate architecture clearly to technical and non-technical audiences alike.

Uxxu is built around the C4 model because it provides the right balance between structure and flexibility. Teams can document complex distributed systems without getting lost in implementation details, and they can communicate architecture decisions consistently across the organization.

Unlike generic diagramming tools, Uxxu treats architecture elements — systems, actors, applications, containers, components, and stores — as first-class entities. This means diagrams stay consistent, relationships are tracked, and the architecture model can be analyzed to surface insights about complexity, dependencies, and technology health.

Who Uses Uxxu

Engineering Teams

Software engineers use Uxxu to document microservices, understand system boundaries, and onboard new team members faster. Architecture diagrams become a shared reference that evolves alongside the codebase rather than lagging behind it.

Software Architects

Architects use Uxxu to maintain a living architecture model across multiple teams and domains. Dependency intelligence and technology lifecycle management help architects track technical debt and prioritize modernization work.

Engineering Managers

Managers use architecture analytics to understand system complexity, identify bottlenecks, and make informed decisions about where to invest in refactoring and simplification.

Platform Teams

Platform and infrastructure teams use Uxxu to document deployment architectures, service dependencies, and infrastructure components. Connected diagrams make it easy to see how platform services relate to product systems.
