RAGFlow

RAGFlow is InfiniFlow's open-source RAG engine with agent features. Rechecked 2026-08-17: github.com/infiniflow/ragflow had 88,659 stars, license Apache-2.0. The README still points cloud sign-up at cloud.ragflow.io. ragflow.io/pricing 404s. Do not invent a Hobby $X or Free 10k-page cloud row. Self-host is $0 software; you pay your own models, GPU, and ops.

Compare Dify if you wanted a public Sandbox / Professional $59 / Team $159 canvas, and LangChain if you wanted a code-first MIT library instead of a RAG appliance.

Key Features

• Document-in, cited answer-out: Layout-aware parsing (tables, images) plus retrieval with citations. Treat the live parser list as the catalog.
• Agents on top of RAG: The GitHub description now pairs RAG with agent capabilities. Recheck the current agent docs before you promise a full Dify replacement.
• Self-host first: Docker / source on GitHub. Cloud is a separate signup with no public price card we could open.
• Templates: Marketing still mentions industry templates. Do not freeze a 2024 template count.

Use Cases

• Teams that will run RAG on their own cluster and accept Apache-2.0 ops.
• People comparing RAGFlow vs Dify on public meters: Dify has one; RAGFlow cloud did not.
• People who only needed a scanner slogan: this is a RAG engine, not OCR-as-a-service.

Limitation: We did not re-verify every parser format or a hosted seat fee. The old "quality in, quality out" essay is out.

Pricing

No public cloud dollar table on 2026-08-17.

If a leftover blog still lists a priced RAGFlow Cloud SKU, treat the missing table as the source.

Getting Started

1. Read the README on github.com/infiniflow/ragflow.
2. Self-host before you assume cloud is free.
3. Open cloud.ragflow.io only to see current in-app billing.
4. Recheck Dify if you needed a public $59 / $159 comparison this week.

Frequently Asked Questions

Is RAGFlow free?

The software is Apache-2.0. Hosted billing was not on a public price page.

Same as Dify?

Both do RAG and agents. Dify publishes cloud dollars. RAGFlow's public site did not.

Is it just a document scanner?

No. It is a RAG engine that parses documents so a model can cite them.

Alternatives

• Dify: Visual agent/RAG cloud with public seats.
• LangChain: Code-first MIT agents.

Tips

1. Quote 88,659 stars and Apache-2.0, not a fake cloud fee.
2. Do not paste "generic AI document scanner" into a deck.
3. Recheck cloud.ragflow.io before you promise a hosted quota.

Conclusion

RAGFlow is an Apache-2.0 RAG engine with a cloud signup and no public dollar table, not a three-bullet scanner blurb. Start at github.com/infiniflow/ragflow, then decide whether Dify already covers the workspace you need.
