Compare R2R and RAGFlow side by side. Both are tools in the RAG Frameworks category.
Updated April 29, 2026
Choose R2R if fully open-source with option to self-host for complete control.
Choose RAGFlow if best document parsing in the OSS RAG space — tables and OCR done right.

Curated quotes from Hacker News, Reddit, Product Hunt, and review blogs. Dates shown so you can judge whether early criticism still applies.
“RAGFlow's parsing engine uses deep learning to understand document structure — recognizing tables, extracting text from images via OCR, preserving formatting.”
“Has become a key infrastructure component for enterprise knowledge bases, compliance-focused AI, research assistants, and multi-source data analysis.”
“Every answer generated by RAGFlow includes citations pointing back to source documents and specific chunks — critical for legal, healthcare, and finance.”
“April 21, 2026 release adds seven prebuilt ingestion pipeline templates, sandbox code execution, chart generation, and user-level memory storage.”
R2R (RAG to Riches) is an advanced open-source AI retrieval system built by SciPhi, a Y Combinator-backed company, supporting production-ready Retrieval-Augmented Generation with state-of-the-art features built around a RESTful API. The framework offers multimodal content ingestion, hybrid search combining semantic and keyword approaches, knowledge graphs for connected data understanding, and comprehensive document management capabilities. R2R includes a Deep Research API, a multi-step reasoning system that fetches relevant data from knowledge bases and/or the internet to deliver richer, context-aware answers for complex queries. The platform is available as both SciPhi Cloud managed service and a self-hostable solution via pip installation, with the cloud offering featuring a generous free tier and no credit card requirement. Built by AI veterans with extensive open-source contributions, R2R provides advanced retrieval and multi-step reasoning at scale without infrastructure burden.
RAGFlow is Infiniflow's open-source RAG engine that fuses retrieval-augmented generation with agent capabilities to create a superior context layer for LLMs. With 78,300+ GitHub stars, it's one of the leading RAG-focused projects on GitHub and is widely used for enterprise knowledge bases, compliance-heavy industries, and research assistants.
RAGFlow's parsing engine uses deep learning to understand document structure — recognizing tables, extracting text from images via OCR, preserving formatting relationships, and handling multi-language content. It supports Word, slides, Excel, txt, images, scanned copies, structured data, and web pages. Retrieval combines vector search, BM25, and custom scoring with advanced re-ranking, and every answer ships with citations pointing back to source documents and specific chunks — critical for legal, healthcare, and finance.
Released April 21, 2026, the latest version added seven prebuilt ingestion pipeline templates, lets agent apps be published, supports sandbox code execution and chart generation, and adds user-level memory storage and retrieval. Free open-source under Apache 2.0, with paid enterprise and managed offerings (contact Infiniflow).
Frameworks and tools for building retrieval-augmented generation pipelines—document parsing, chunking, indexing, and query engines that connect LLMs to your data.
