Two Platforms, Two Philosophies
Dify (152,103 stars, fetched 2026-08-12) and RagFlow (87,273 stars, fetched 2026-08-12) both solve 'chat with your documents'. The similarity ends there. Dify is an LLM application platform with RAG as one of many features. RagFlow is a document intelligence engine with RAG as the entire product.
What Dify Does Best
- Full app lifecycle: build a chatbot, publish it as a web app or API, add logging and user management. It is an end-to-end product.
- Agent workflows: visual workflow builder with tools, nodes and conditions - not just retrieval.
- Model-agnostic: 100+ model providers, one switch to change the brain.
- The cost: its default RAG (chunk + embed) is solid but not magical; very messy documents will still produce messy answers.
What RagFlow Does Best
- Deep document understanding: template-based chunking, table extraction, OCR - it treats documents as structured things, not plain text.
- Grounded answer generation: citations with highlighted source snippets out of the box.
- The cost: it is a document pipeline, not an app platform. You build the surrounding app yourself.
The Decision Table
| Need | Pick |
|---|---|
| End-to-end chatbot product with user management | Dify |
| Answer questions from messy PDFs with citations | RagFlow |
| Agent workflows beyond retrieval | Dify |
| Table-heavy documents (invoices, reports) | RagFlow |
| Both, later | Start Dify, add RagFlow as a document pipeline via API |
The Integration Reality
The 2026 pattern many teams use: Dify as the app front end (chat, users, workflow), RagFlow as the document brain behind it. Dify's API-based tool nodes can call RagFlow's retrieval API, giving you Dify's product polish and RagFlow's document depth. Both are MIT/Apache licensed and self-hostable.
The Numbers That Matter
- Dify: 152,103 stars; TypeScript; huge plugin ecosystem; the default choice for product builders.
- RagFlow: 87,273 stars; Go; focuses on document quality; the choice when the document is the problem.
