What does CodeViz (YC S24) do?
CodeViz (YC S24) is a collaborative diagramming tool that automatically visualizes code architecture for software development teams. It analyzes codebases across all major programming languages to build complete architecture models, creating stakeholder-ready diagrams that stay in sync with the actual code. Every element in the diagrams is fully editable and links directly back to the source code, ensuring documentation remains accurate as the codebase evolves.
The tool works by generating on-demand contextual views for specific workflows, API paths, or data flows. It shows dependencies, data movement, and where each step lives in the codebase. CodeViz (YC S24) uses industry-standard C4 and UML modeling practices, so teams get professional architecture diagrams without needing to become modeling experts. It integrates with development tools including VS Code, GitHub, Jira, Slack, and Figma, making it part of the existing workflow.
Software engineering teams benefit most from CodeViz (YC S24), particularly those working on large, complex codebases. It helps engineers save time on PR reviews by visualizing code changes instantly, provides clarity by linking tickets to code visually, and improves team alignment through shared architecture context. The tool claims to save developers an average of 10 hours monthly and delivers 40x ROI for engineering organizations.
