GitDiagram

Get the architecture of a public GitHub repository from GitDiagram (gitdiagram.com): a written explanation of how the codebase is organized, its main components with the source paths they live in, how those components connect, and a Mermaid flowchart of the whole system, plus a link to the interactive diagram, where every component opens its code on GitHub. Use it whenever the user wants to understand, visualize, map or explain a GitHub repository's or open-source project's architecture, structure, main modules or data flow, wants an overview before reading unfamiliar code, or asks for an architecture or system diagram of a repo. Read-only and fast: it returns the diagram GitDiagram has already made. If none exists yet, it returns a link that makes one when opened in a browser. Public repositories only. In chat apps that show interactive views, the result also appears as a zoomable diagram whose components open their code on GitHub.

Search GitDiagram's library of ready-made architecture diagrams of public GitHub repositories by owner or repository name. Matches any part of "owner/repo" (e.g. "langchain", "vercel/", "react-native") and returns up to 10 repositories, most-starred first, each with its interactive diagram link. Use it to find a project's exact owner/repo from its name, or to list which repositories of an owner or topic already have diagrams. It searches repository names only, not code or file contents.

Get GitDiagram's narrated explainer video of a public GitHub repository, if one has been made: the link to watch and share it, its title and length, and the full narration transcript, a plain-language walkthrough of what the project is for, what people do with it and how its main parts fit together. Use it when the user wants a video about a repository, something to watch or share instead of read, or a short spoken-style summary of a project. Read-only: it never makes a video; when none exists it says so and links the page where one can be made.
