Generate clickable architecture diagrams from public GitHub repos with GitDiagram

Turn a public GitHub repository into an interactive architecture diagram before onboarding, code review, or agent handoff.

Prerequisites

Public GitHub repository URL, web access, optional self-hosted OpenAI or OpenRouter configuration

Installation

Use the upstream install or setup path that matches your environment:

• git clone https://github.com/ahmedkhaleel2004/gitdiagram.git
• docker-compose up --build -d

• bun run install:backend

• cp .env.example .env
