Documentation is the first casualty of fast-moving codebases. Architecture diagrams go stale the moment they're created, and no one has time to manually update them after every sprint. That's why we built the GitHub-to-diagram feature in ArchitectAI.
How It Works
- Paste any public GitHub repository URL into ArchitectAI.
- The AI analyzes the repo structure: directories, config files, package manifests, Docker files, and source code.
- It identifies services, databases, queues, APIs, and their relationships.
- A complete architecture diagram is generated with proper grouping and labeled connections.
What the AI Detects
ArchitectAI looks at multiple signals in your codebase to infer the architecture:
- Dockerfile and docker-compose.yml for service definitions.
- Package.json, requirements.txt, go.mod for technology stack.
- API route files for endpoint mapping.
- Database migration files and ORM models for data layer.
- Environment variables and config for external service integrations.
- GitHub Actions / CI config for deployment pipeline.
Real-World Use Cases
Teams use the GitHub-to-diagram feature for onboarding ("here's how our system looks"), architecture reviews ("is this how it should look?"), and RFCs ("here's the current state, and here's the proposed change"). It's also great for open-source projects that want to add architecture documentation to their README.
For private repos, you can paste key files (like docker-compose.yml or a project structure) directly into the editor and the AI will generate the diagram from that context.
Try It Now
Head to the ArchitectAI editor and switch to GitHub mode. Paste a repo URL and watch the architecture appear. You can then refine, export, and share it with your team. No signup required for your first diagram.
