Uxxu

What is Uxxu?

Uxxu is a software architecture platform built for C4 models. It helps teams map systems, containers, components, and dependencies in one shared workspace, so architecture stays clear and connected over time. You can create linked C4 diagrams, collaborate in real time, and move from high-level context down to detailed component views without losing the thread. It also analyzes your model to surface complexity, dependencies, and structural risks like single points of failure. For AI workflows, Uxxu includes an MCP server so tools like Claude Code, Codex, and OpenClaw can turn written specs into C4 diagrams inside your workspace. It also offers codeToC4, which can read a repository and generate living architecture diagrams from code. Diagrams can be embedded in docs, Notion, Medium, and websites while staying synced with the main model.
