- **Official website**: https://gitdiagram.com

## Key features

- Interactive architecture visualization from GitHub URLs
- One-minute AI-generated narrated explainer videos
- Direct file linking from diagram components
- Export as PNG or Mermaid.js source
- Remote MCP server for AI agent integration

## Pricing

**Model**: Free

100% free and open-source; the project is sustained through community sponsorship with no paid plans or subscriptions.

## Who it is for

- **Best for**: Rapid architectural orientation for developers onboarding to unfamiliar codebases, quick repository exploration, and generating visual starting points for documentation.
- **Not ideal for**: Projects requiring high-precision, hand-curated diagrams, deep comprehensive code analysis, or persistent, complex version-controlled visual artifacts.

## Verdict

A high-utility, zero-setup tool perfect for quick codebase insights; while diagrams are sketches rather than exhaustive documentation, its ease of use and ability to link directly to code make it an essential resource for initial orientation.

## Recent updates

Added support for AI-generated narrated explainer videos for repositories and a remote MCP server for AI agent interactions.
