The honest brief
CrewAI
Models work as a crew of role-typed agents that delegate to each other, built standalone rather than on LangChain.
- Role-based multi-agent model
- Independent of LangChain
- Model-agnostic
- Good for research pipelines
- Opinionated structure
- Less flexible than graph frameworks
- Debugging multi-agent runs is hard
LlamaIndex
Retrieval-first where LangChain is orchestration-first — LlamaParse is the go-to for PDFs that defeat normal parsers.
- Best-in-class RAG primitives
- LlamaParse for hard documents
- Python + TypeScript
- Managed LlamaCloud option
- Narrower than full orchestration frameworks
- LlamaCloud parsing is paid
- API churn between versions
