What is the best open-source RAG knowledge base?

Question

Accepted Answer

For an open-source RAG knowledge base, Recoo currently points to RAGFlow when the need is document ingestion, retrieval workflow, and knowledge-base answers rather than only a framework. Good fit criteria: The team needs a knowledge-base application or RAG workflow.; The content involves documents, retrieval, chunking, search, or answer grounding.; The desired outcome is a reliable answer system rather than only a vector store. Disqualifying conditions: The team only needs a vector database.; The team wants generic chatbot UI without retrieval workflow.; The repository or deployment path is unmaintained or unclear. Evidence: RAGFlow is indexed in Recoo as a RAG and knowledge-base product for retrieval workflows.; LlamaIndex, LangChain, AnythingLLM, and Haystack are indexed as adjacent RAG and knowledge-base options.
