This project presents a production-grade AI-powered GitHub Repository Intelligence System developed using a modern full-stack architecture. The system leverages multi-agent artificial intelligence workflows through LangGraph, backend API services through FastAPI, interactive visualization through Streamlit, and persistent cloud-based storage using PostgreSQL via Supabase. The platform automatically: - π Analyzes GitHub repositories - π Extracts documentation structure - π§ Evaluates repository quality - π¬ Provides conversational AI interaction - πΎ Maintains persistent user sessions.The architecture follows a scalable SaaS-oriented design integrating authentication, persistent storage, real-time chat interfaces, and deployment-ready infrastructure.
Modern software repositories contain large amounts of documentation, source code, metadata, and development history, making manual evaluation increasingly difficult. This project introduces an AI-driven platform capable of automating repository analysis using a LangGraph multi-agent orchestration pipeline integrated with cloud-based SaaS architecture. Key capabilities include repository analysis, metadata extraction, conversational interaction, persistent session management, and intelligent documentation evaluation.
The major objectives of this project are:
This project is deployed using Render with separate frontend and backend services.
Frontend (Streamlit UI):
https://ai-github-intelligence-system-front-end.onrender.com
Backend (FastAPI):
https://ai-github-intelligence-system.onrender.com
The backend is hosted on Renderβs free tier, which means it may go to sleep after periods of inactivity.
When this happens:
502 Bad GatewayIf the backend is asleep, simply this URLs to wake it up:
Once accessed, the backend will start up and subsequent requests will be fast.
Render free services spin down after periods of inactivity to save resources. This is expected behavior and not a bug in the application.

The intelligence layer is implemented using LangGraph, enabling specialized agents to collaborate during repository analysis.
| Agent | Responsibility |

| π Content Agent | README summarization and content extraction |
| π·οΈ Metadata Agent | Repository metadata and keyword extraction |
| ποΈ Structure Agent | Documentation structure validation |
| π Quality Agent | Repository quality scoring |
| π§Ύ Reviewer Agent | Aggregation and final decision making |
| π¬ LLM Agent | Conversational repository interaction |

The backend is implemented using FastAPI and provides RESTful API endpoints for authentication, repository analysis, session management, and chat interaction.
The application uses JWT-based authentication with protected API routes, refresh token rotation, and user-specific data isolation.
The system uses Supabase PostgreSQL for persistent storage and session management.
Users β Sessions β Messages β Repository Analysis Results
The database supports persistent chat history, repository tracking, and session recovery.
The frontend is built using Streamlit and provides:
Displayed metrics include GitHub stars, forks, quality scores, and confidence scores.
The system was evaluated using public GitHub repositories deployed on cloud infrastructure.

To ensure reliability, scalability, and production readiness, the system underwent multiple layers of testing across the backend architecture and AI workflow pipeline.
Comprehensive API testing was carried out using pytest and FastAPIβs TestClient to validate the complete request-response lifecycle of the platform.
These tests verified:
The E2E tests simulated real user interactions with the API to ensure the backend behaves correctly under production-like conditions.
Integration testing was performed on the agentic workflow graph to validate communication and interoperability between interconnected AI components.
The tests ensured correct interaction between:
These tests verified that data flowed correctly across the graph-based architecture and that chained agent operations produced stable and coherent outputs.
Unit tests were conducted on individual tools and backend utility functions to ensure isolated component correctness.
This included testing for:
The unit testing process improved maintainability and reduced the likelihood of regression errors during future feature expansion.
The testing infrastructure leveraged the following technologies:
pytestFastAPI TestClientPostgreSQLJWT authentication testingMock request validationStructured API response verificationThis multi-layered testing strategy ensured that the platform remained robust, secure, scalable, and production-ready while supporting continuous development and deployment workflows.
The developed system successfully demonstrated automated repository analysis, metadata extraction, AI-powered summarization, documentation evaluation, and persistent conversational interaction.
The multi-agent architecture improved scalability, modularity, and intelligent decision-making while supporting production-grade SaaS deployment capabilities.
