RAGFlow is an open-source RAG engine built on deep document understanding, extracting clean structure from complex files to give LLMs grounded, cited answers.
GraphRAGGraphRAG from Microsoft Research extracts entities and relations into a knowledge graph before retrieval, dramatically improving answers to global, multi-hop questions over large corpora.
RAGFlow is rAG engine, while GraphRAG is rAG pipeline. Their licenses differ (Apache-2.0 vs MIT), which matters if you ship a commercial product. RAGFlow leans more intermediate-friendly, whereas GraphRAG is more suited to advanced users. They also differ in how they run (Self-hosted vs Partial). In short, RAGFlow fits RAG over messy, complex documents, and GraphRAG fits complex question-answering over big document sets.
Choose RAGFlow for RAG over messy, complex documents. Choose GraphRAG for complex question-answering over big document sets.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
RAGFlow is generally the easier of the two to get started with, while GraphRAG rewards more setup with more control.
RAGFlow is free and open source (Apache-2.0), and GraphRAG is free and open source (MIT). Neither charges for the core software.
RAGFlow: self-hosted · GraphRAG: partial. Both can be used without sending your data to a third-party cloud where their setup allows.
Choose RAGFlow for RAG over messy, complex documents. Choose GraphRAG for complex question-answering over big document sets.
