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

When to pick which

CrewAI leans on Agent framework as a headline capability; LlamaIndex treats it as secondary.
