CodeViz is a code visualization and architecture diagramming platform that automatically generates visual representations of codebases dependency graphs, module relationship diagrams, call flow charts, and architecture overviews from source code analysis rather than requiring developers to maintain diagrams manually.
As codebases grow and evolve, the gap between architectural documentation and actual code structure typically widens until diagrams are misleading rather than illuminating.
CodeViz solves this by generating diagrams from the current state of the code, ensuring that visual representations always reflect reality rather than historical intent.
The platform's different visualization types serve different understanding needs: dependency graphs reveal which modules import which others and identify circular dependencies that create maintenance problems; call flow diagrams trace execution paths through the code for specific entry points, making it easier to understand what happens when a particular API endpoint or function is invoked; module size and complexity heat maps highlight where the codebase is most dense and where attention is most needed.
Interactive diagrams allow developers to zoom into specific subsystems and navigate the codebase spatially rather than by file tree browsing alone.
CodeViz integrates with GitHub and GitLab to generate diagrams directly from repository content, and supports major languages including Python, JavaScript/TypeScript, Java, Go, Ruby, and C#.
Generated diagrams can be exported as SVG or PNG for documentation, embedded in Confluence or Notion wikis, or shared as interactive web links.
For engineering teams onboarding new members, conducting architecture reviews, planning refactoring work, or communicating system design to non-engineering stakeholders, CodeViz provides the accurate, current architectural visualization that makes complex codebases comprehensible without the maintenance burden of hand-drawn diagrams.
