Highlighted rows are where these differ.
Unstructured
- PDF, DOCX, HTML, email and more into elements
- The unglamorous layer most RAG failures actually come from
Best for the ingestion step nobody enjoys writing.
LlamaIndex
- Deep document handling and many indexing strategies
- The common advice is LlamaIndex for retrieval, LangGraph for orchestration
Best for PDFs, knowledge bases, structured data.
RAGFlow
- Strong document parsing built in
- The usual entry point for non-developers
Best for teams without a Python engineer.
