Score: 7.8/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 7)

Vedana is an open-source multi-agent RAG system that uses a knowledge graph and vector store to answer structured queries with traceable results, moving beyond traditional similarity-based search. Its innovative approach treats the LLM as an interpreter that issues Cypher queries and vector searches, and the project is well-documented with architecture diagrams, API references, and deployment guides.

Target audience: backend devs, data engineers, ai engineers
