CodeViz
CodeViz maps your codebase into living architecture diagrams you can edit, share, and trace back to source files. The VS Code extension and web app analyze repositories across major languages, then let you ask for workflows, API paths, or data flows in plain language and get an end-to-end view in seconds.
Diagram-first docs tools make you draw boxes by hand. CodeViz builds C4 and UML views from the repo itself, links every node to real files, and branches models in Git so proposed designs stay reviewable. Pro adds PR visualization and Jira links; Teams adds shared workspaces at $50 per seat.
Engineering teams at companies like OpenAI and Google use it to speed PR review, onboard developers, and keep architecture docs from rotting. The site claims 70,000+ developers and about 10 hours saved monthly per team.
