codeToC4 by Uxxu
Your Codebase Already Knows Its Architecture. Now Your C4 Diagrams Can Too.
Uxxu's codeToC4 analyzer reads your repository and automatically generates up-to-date C4 context, container, and component diagrams so your architecture documentation is never stale again.
Be among the first to sync your architecture with your code.
Quick Answer
What codeToC4 gives you
A short version for buyers, readers, and AI systems.
- Generate a code to C4 diagram directly from your repository.
- See your C4 model from code at any commit, release, or branch.
- Compare structural changes visually instead of relying only on line diffs.
Why teams care
code to C4 diagram
Turn a live repository into structured context, container, and component views.
C4 model from code
Start from what the system actually is, then refine it with human judgment.
Automatic architecture diagram from codebase
Keep architecture current even when AI coding tools speed up change across the entire stack.
The problem
C4 Diagrams Are Brilliant. Keeping Them Current Is a Nightmare.
If you've invested in C4 model documentation, you already know the value. It gives your team a clear, layered map of the system that a new engineer, an architect, and a CTO can all read. Context to container to component. Zoom in, zoom out. Architecture as a shared language.
The problem is not the model. The problem is time. In a world where a single afternoon of AI-assisted coding can reshape ten services, diagrams are outdated before you finish drawing them. Nobody has time to update them manually, and nobody trusts documentation they know is behind the code.
That is exactly when expensive architectural decisions start happening without a map. Vibe coding is fast. Architecture diagrams are slow. The gap between them is where technical debt is born.
The solution
Introducing codeToC4: Architecture Documentation That Stays in Sync with Your Code
Uxxu's codeToC4 analyzer connects directly to your Git repository and does what used to be impossible: it reads your actual codebase and generates accurate, structured C4 diagrams automatically. No manual updates, no silent drift, and no more architecture diagrams that developers distrust and eventually ignore.
Automatic diagram generation
Point it at your repository. codeToC4 analyzes structure, service boundaries, and dependencies, then generates context, container, and component diagrams inside Uxxu.
Architecture at any point in time
Because the analyzer understands Git history, you can inspect architecture at a commit, release tag, or branch and answer questions like what the system looked like before a refactor.
Branch-aware architecture
Switch branches and see different structural views. Compare a feature branch to main and understand what changed in components, dependencies, and boundaries.
Visual architecture diffs
Review architecture changes the way you review code: with a visual diff of what was added, removed, and modified at the container and component levels.
Why now
Architecture Documentation for the Age of AI Coding
We are at a turning point. AI coding tools are making developers dramatically more productive, but they are also making codebases change faster than any human documentation process can keep up with.
The teams that thrive in this world will not be the ones who write the most code. They will be the ones who maintain the clearest picture of what they are building and why their architectural decisions were made.
codeToC4 is our answer to that challenge: a bridge between the living reality of your Git repository and the structured clarity of C4 architecture models.
Features at a glance
Everything you need to keep architecture and code in sync
Who it's for
Built for the people who care most about architectural quality
For software architects
You designed the system. Now you can see exactly how it has evolved and catch architectural drift before it becomes a refactoring crisis.
For engineering managers and CTOs
Onboard faster, make decisions with current information, and understand what changed in the last sprint at a structural level instead of only at a ticket level.
For senior developers
Stop updating diagrams by hand and stop building from docs you already know are wrong. Work with a real-time picture of the system you are changing.
Vision
The future of software development is architectural, not syntactic
For most of software history, the hard part was writing code. The future looks different. AI systems are handling more and more of the syntax. The high-value work that remains human is architectural: what to build, how the pieces should relate, where the boundaries should be, and how the system should evolve.
At Uxxu, we believe the developers who shape that future will be the ones who think in systems, not lines. codeToC4 is our first step toward making that way of working accessible to every team, not only the ones with the luxury of dedicated architecture time.

FAQ
Common questions
What languages and frameworks does codeToC4 support?
We are starting with the most common backend and frontend stacks. Join the waitlist to tell us which language you need first. We are prioritizing early access demand.
Does it replace manual C4 diagramming?
No. codeToC4 generates a baseline that reflects your actual code. You can then edit, annotate, and extend it inside Uxxu with the context that cannot be inferred from source alone.
How does it handle private repositories?
We take security seriously. codeToC4 can run as a local analysis step that sends structural metadata to Uxxu without sending raw source code. Full self-hosted options are planned.
What if my codebase is a monolith, not microservices?
C4 works for monoliths too. codeToC4 is designed to help teams understand both monoliths and distributed systems, especially at the container and component levels.
