Free AI-powered GitHub Repo Visualizer

GitDiagram is a free, open-source, AI-powered tool that transforms any GitHub repository into an interactive, visual diagram.

This tool addresses the challenge of understanding large codebases quickly, particularly when onboarding new team members or exploring unfamiliar projects. By generating interactive visualizations, GitDiagram reduces the time spent manually mapping out repository structures and dependencies.

Features

Interactivity: Components within the generated diagram are clickable. This allows you to direct navigation to the corresponding source files and directories on GitHub.
Fast Generation: Generates diagrams with speed and accuracy using Claude 3.5 Sonnet API.
Customization: You can modify and regenerate diagrams by providing specific instructions to tailor the visualization.

Use Cases

Codebase Analysis. Developers working on large or unfamiliar repositories can use GitDiagram to understand file structures and dependencies quickly.
Project Documentation. Teams can generate diagrams to visually document project architecture, aiding onboarding and collaboration.
Educational Purposes. Students and educators can leverage the tool to teach or learn about code organization and software architecture.
Client Presentations. Freelancers or agencies can create polished visuals of repositories to explain project structures to non-technical stakeholders.
Open Source Contributions. Contributors can use GitDiagram to familiarize themselves with repository layouts before diving into the code.

How to Use It

Visit the GitDiagram website.
Paste the GitHub repository URL you wish to visualize.
Click the “Diagram” button and wait a few seconds for the AI to process and generate the interactive diagram.
Alternatively, modify any GitHub URL by replacing “hub” with “diagram”. For instance, to visualize https://github.com/fastapi/fastapi, visit https://gitdiagram.com/fastapi/fastapi.
Explore the diagram by clicking on components to navigate to the corresponding files and directories.
