GitDiagram
AI-generated architecture diagrams and explainer videos for GitHub repos
What it is
A web app that reads a GitHub repository and produces an interactive Mermaid architecture diagram with a written explanation, plus optional one-minute narrated videos. Diagram components link to the files and folders they describe, and diagrams export as PNG or Mermaid source. It also runs as a remote MCP server so coding agents can query a repo's structure. Developers getting oriented in an unfamiliar codebase use it by swapping 'hub' for 'diagram' in a GitHub URL, and it can be run on your own infrastructure with your own API keys.
