Highlighted rows are where these differ.
LightRAG
- Dual-level retrieval over a lighter graph
- Runs on CPU, which GraphRAG does not comfortably
Best for graph RAG on modest hardware.
RAGFlow
- Strong document parsing built in
- The usual entry point for non-developers
Best for teams without a Python engineer.
