DeepWiki

From DeepWiki.com’s own pages (and Devin’s official docs), the service auto‑generates a small set of practical, repo‑grounded diagrams. The ones you’ll repeatedly see are:

  • System architecture diagrams – high‑level component maps of the repo, often with variants (e.g., dev vs. prod). Examples: “Architecture Overview” for Google’s LangGraph quickstart and Dify’s system architecture. ([DeepWiki]1)
  • Data‑flow diagrams – end‑to‑end data movement through services/layers, sometimes paired with state management notes. Examples in LangGraph quickstart and other repos’ “Data Flow” pages. ([DeepWiki]1)
  • Communication/interaction flow diagrams – how frontends, backends, and services talk (request/response or streaming paths). Examples: “Frontend‑Backend Communication Flow” (LangGraph quickstart) and “Communication Flow” pages in other repos. ([DeepWiki]1)
  • Workflow / state diagrams – stepwise or state‑graph views of an internal pipeline or agent workflow (e.g., LangGraph StateGraph). ([DeepWiki]1)
  • Code‑entity mapping / relationship diagrams – maps from conceptual components to concrete classes/files (often titled “Code Entity Relationship/Mapping”). Examples in sawwent/pr‑agent, trinodb/trino, and others. ([DeepWiki]2)
  • Directory/structure diagrams – a visual of the source tree or module layout when that helps navigate the repo. Example in sawwent/pr‑agent. ([DeepWiki]2)

A few notes:

  • These aren’t generic templates: each diagram page lists “Sources” (actual files/paths) that the diagram is grounded in, which is a tell that DeepWiki.com generated it from the repository’s contents. See the “Architecture Overview” page where diagrams cite files like graph.py, App.tsx, docker-compose.yml. ([DeepWiki]1)
  • Official docs from Cognition (Devin) also state that DeepWiki “automatically generates architecture diagrams, documentation, and links to source code” for public repos. ([Devin Docs]3)

If you want, tell me a specific repo and I’ll pull up its DeepWiki page to list exactly which diagrams it generated for that codebase (the titles vary by repo).
