Graph Enhanced RAG Vector Databases

Systems combining knowledge graphs (Neo4j, NebulaGraph, etc.) with vector search for multi-hop reasoning and explainable retrieval. Does NOT include standalone vector databases, simple RAG without graph components, or non-retrieval knowledge graph applications.

There are 16 graph enhanced rag tools tracked. The highest-rated is zilliztech/vector-graph-rag at 44/100 with 2 stars.
