What each one is
DSPy
DSPy from Stanford is a framework for programming LLMs with composable modules and optimizers that automatically tune prompts instead of hand-crafting them.
- Replaces prompt-hacking with optimization
- Composable, reusable modules
- Strong research backing
RAGFlow
RAGFlow is an open-source RAG engine built on deep document understanding, extracting clean structure from complex files to give LLMs grounded, cited answers.
- Strong document layout understanding
- Grounded answers with citations
- Self-hostable web UI
Key differences
DSPy is lLM programming framework, while RAGFlow is rAG engine. Their licenses differ (MIT vs Apache-2.0), which matters if you ship a commercial product. DSPy leans more advanced-friendly, whereas RAGFlow is more suited to intermediate users. They also differ in how they run (Cloud-optional vs Self-hosted). In short, DSPy fits optimizing LLM pipelines systematically, and RAGFlow fits RAG over messy, complex documents.
Which should you choose?
Choose DSPy for optimizing LLM pipelines systematically. Choose RAGFlow for RAG over messy, complex documents.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
Is DSPy or RAGFlow easier to use?
