Project Description: GitDiagram

What is the project about?

GitDiagram is a tool that automatically generates interactive system design/architecture diagrams from GitHub repositories. It visualizes the structure and relationships within a codebase, making it easier to understand.

What problem does it solve?

It addresses the challenge of understanding large and complex codebases, especially when onboarding to a new project (open-source or otherwise). Manually navigating a large repository can be overwhelming; GitDiagram provides a high-level overview.

What are the features of the project?

  • Instant Visualization: Creates a diagram of a GitHub repository's structure.
  • Interactivity: Diagram elements are clickable, linking directly to the corresponding files and directories in the GitHub repository.
  • Fast Generation: Uses AI (Claude 3.5 Sonnet, previously o3-mini) to quickly produce diagrams.
  • Customization: Allows users to modify and regenerate diagrams with custom instructions.
  • Private Repository Support: Diagrams can be generated for private repositories using a GitHub personal access token or by self-hosting.
  • API Access: A public API is planned (Work In Progress) for integration with other tools.

What are the technologies used in the project?

  • Frontend: Next.js, TypeScript, Tailwind CSS, ShadCN
  • Backend: FastAPI, Python, Server Actions
  • Database: PostgreSQL (with Drizzle ORM)
  • AI: Claude 3.5 Sonnet (and previously OpenAI's o3-mini)
  • Diagramming: Mermaid.js
  • Deployment: Vercel (Frontend), EC2 (Backend)
  • CI/CD: GitHub Actions
  • Analytics: PostHog, Api-Analytics

What are the benefits of the project?

  • Improved Codebase Understanding: Provides a visual overview, making it easier to grasp the structure of a project.
  • Faster Onboarding: Helps new developers (or anyone unfamiliar with a codebase) get up to speed quickly.
  • Enhanced Collaboration: Facilitates communication and understanding among team members.
  • Simplified Documentation: Can serve as a form of automatically generated documentation.
  • Easy Navigation: Direct links to source code from the diagram.

What are the use cases of the project?

  • Onboarding to new projects (open-source or internal).
  • Understanding existing codebases for maintenance or refactoring.
  • Documenting software architecture.
  • Explaining code structure to others (e.g., during code reviews or presentations).
  • Analyzing dependencies and relationships within a project.
  • Integrating with other development tools via the planned API.
