  • Starter: $29 per month, includes 50 Apps, 5 team members, 5 GB dataset storage, 5,000 credits/month, API key available.
  • Pro: $129 per month, includes Unlimited Apps, 20 team members, 50 GB dataset storage, 20,000 credits/month, API key available.
  • Enterprise: Contact for pricing, offers BYOC deployment, On-premises deployment, Dedicated support, and Custom SLA.

Pros

  • +Deep document parsing capabilities, respecting document structure (tables, headers, sections) for superior retrieval precision.
  • +User-friendly and attractive dashboard, noted as 'great and easy to use' for an open-source RAG project.
  • +Emphasizes a 'citation-first mindset', providing transparent and traceable answers.
  • +Integrated agent platform with a new Memory module for real-time retrieval of historical experiences.
  • +Supports a wide range of data sources and LLM integrations, including Google BigQuery, Confluence, S3, Notion, and OpenAI GPT-5.

Cons

  • Can be 'resource-hungry' due to its deep document understanding processes (OCR/Layout analysis).
  • The API-driven workflow might be opinionated, potentially requiring hands-on operational effort for tuning.
  • Debugging specific parsing failures, especially with unusual PDF formats, may necessitate delving into container logs.
  • API key is not available in the Free tier, limiting integration capabilities for basic users.

Similar Tools

RAGFlow vs Competitors

RAGFlow distinguishes itself in the RAG and AI agent landscape by combining a visual, low-code builder with a strong emphasis on deep document understanding and a 'citation-first mindset'.

1

Provides a visual, low-code platform for building and operating AI agents and LLM applications, integrating RAG, workflows, and LLMOps.

Similar to RAGFlow in offering a visual builder and end-to-end solution for RAG and agents, but Dify focuses more broadly on LLM application development and LLMOps, whereas RAGFlow emphasizes deep document understanding.

2

Offers a drag-and-drop visual interface for building LLM applications and AI agents based on LangChain, simplifying workflow creation without extensive coding.

Like RAGFlow, it provides a visual, low-code builder for RAG and agents. FlowiseAI is built on LangChain, offering broad integration with LLM components, while RAGFlow focuses on its proprietary deep document understanding layer.

3

A visual, drag-and-drop platform for building and deploying AI agents and RAG applications, with full Python source access for deep customization.

Langflow provides a visual builder similar to RAGFlow, but it offers more direct access to Python code for customization, making it a strong choice for developers who want visual prototyping with code extensibility.

4

An open-source AI orchestration framework for building production-ready LLM applications, focusing on modular pipelines for RAG, agents, and context engineering.

While RAGFlow offers a visual low-code UI, Haystack is more of a code-centric framework, providing explicit, modular pipelines for fine-grained control over RAG and agent workflows, making it suitable for developers needing high customizability and production-grade features.
