The record

Purpose: RAGFlow describes itself as an open-source RAG engine and integrated agent platform for building a context layer for AI agents.
Data processing: Its built-in ingestion pipeline cleanses and processes multi-format data into semantic representations for retrieval.
Search: Its search combines vector search, BM25, custom scoring, and advanced re-ranking.
Agent workflows: Its visual workflows integrate RAG, tools, and MCPs for agent orchestration.
Model support: RAGFlow lets users connect online, local, and OpenAI-compatible model providers for knowledge bases, chats, search, and agents.
External tools: Agents can connect to external MCP servers over Streamable HTTP or SSE; stdio servers require a gateway or another service exposing a supported endpoint.
Data connectors: Documented data sources include Notion, Google Drive, S3, Microsoft Teams, REST API, and Sitemap.
API and embedding: RAGFlow provides HTTP and Python APIs and supports embedding a Chat assistant in a third-party webpage with an iframe.
Self-hosting: The documentation describes Docker deployment and a browser-accessible service, and gives a minimum build requirement of 4 CPU cores, 16 GB RAM, and 50 GB disk.
Platform caveat: RAGFlow says it tests ARM64 platforms but does not maintain RAGFlow Docker images for ARM; users can build an image themselves on linux/arm64 or darwin/arm64.
Security: By default, RAGFlow validates MCP server URLs and rejects hosts that resolve to loopback, private, link-local, reserved, or other non-public addresses.
Privacy roles: RAGFlow says it typically acts as a controller for personal data it collects for its own purposes and as a processor or service provider for customer data uploaded to its cloud services.
Enterprise support: The Enterprise plan lists dedicated support and a custom SLA.
Intended users: The site describes the platform as built for enterprise and lists solutions for financial services, legal and compliance, manufacturing, and education.
