nano-graphrag

This is a lightweight and easy-to-hack GraphRAG implementation. I find it provides a smaller, faster, and cleaner core GraphRAG functionality, with about 1100 lines of code excluding tests and prompts. It's portable, asynchronous, and fully typed, supporting various backends.

Questions & Answers

What is nano-graphrag?
nano-graphrag is a Python-based project that offers a simplified, faster, and cleaner implementation of GraphRAG, focusing on retaining core functionalities while being easy to read and modify. It provides both global and local graph RAG search capabilities.
Who is nano-graphrag designed for?
It is designed for developers and researchers who find official GraphRAG implementations complex and seek a more approachable, hackable, and lightweight solution. It's also suitable for those needing a portable RAG system with asynchronous operations.
How does nano-graphrag differ from other GraphRAG solutions?
nano-graphrag differentiates itself by its minimal codebase, consisting of approximately 1100 lines of code excluding tests, which makes it significantly easier to understand and hack. It emphasizes simplicity, speed, and cleaner design while maintaining core GraphRAG functionality.
When should I consider using nano-graphrag for my RAG application?
You should consider nano-graphrag when you need a GraphRAG solution that is easy to integrate and customize, requires support for various LLM providers (e.g., OpenAI, Azure, Bedrock, Ollama) and vector/graph databases, or when working with incremental data insertions.
What are some of the key components and integrations supported by nano-graphrag?
nano-graphrag supports various components including OpenAI, Amazon Bedrock, and Ollama for LLMs and embeddings. For vector databases, it works with nano-vectordb (built-in), hnswlib, milvus-lite, and faiss, and for graph storage, it uses networkx or neo4j.
