Pricing Questions

What is included in the free plan?

Every organization in Uxxu includes a free plan that supports up to 100 architecture items. This lets you start modeling your architecture, create C4 diagrams, and explore the platform before committing to a paid plan.

Can I switch plans later?

Yes. You can upgrade or change your plan at any time as your team and architecture grow. Each organization manages its own license independently.

What is an architecture item?

An architecture item is any element in your architecture model, including systems, actors, applications, containers, components, stores, and groups. Diagrams themselves are not counted as items.

Is Uxxu suitable for large teams?

Yes. Uxxu supports organizations of all sizes. The Team and Enterprise plans include real-time collaboration, shared architecture workspaces, and role-based access so multiple teams can work together on architecture diagrams and models.

What is the difference between Starter and Team?

The Starter plan is designed for individual developers who want to model and explore software architecture on their own. The Team plan adds real-time collaboration, shared architecture workspaces, architecture analytics, and dependency intelligence so multiple engineers can design and evolve systems together.

What does the Enterprise plan add?

The Enterprise plan includes everything in the Team plan plus technology lifecycle tracking to monitor deprecated and legacy technologies across your architecture, advanced architecture analytics, priority support, and enterprise integrations for larger organizations managing complex systems across multiple teams and products.

How does Uxxu compare to other architecture tools?

Unlike traditional diagram tools that treat architecture as static drawings, Uxxu models architecture as structured data. Diagrams are interconnected, architecture elements are reusable across projects, and built-in analytics provide insights into complexity, dependencies, and technology usage. This makes Uxxu a living architecture model rather than a collection of isolated diagrams.

Why teams choose Uxxu

Engineering teams use Uxxu to maintain a shared understanding of how their systems are structured. Instead of architecture knowledge being scattered across wikis, documents, and outdated diagrams, Uxxu provides a single platform where teams can design systems using the C4 model, connect diagrams together, track technology usage, and measure architectural complexity over time.

Whether you are a solo architect modeling a new system or a large engineering organization managing dozens of services and teams, Uxxu scales with your architecture. Start with the free plan and upgrade as your projects and team grow.
