Comparison

CrewAI vs LlamaIndex

A like-for-like, spec-level comparison. Both entries are verified against their docs and repo.

CrewAI

Role-playing multi-agent crews.

  • + Intuitive role-and-task mental model
  • + Fast to prototype multi-agent flows
  • − Less fine-grained control than LangGraph
  • − Can be token-inefficient at scale

LlamaIndex

The data framework for LLM applications.

  • + Best-in-class data connectors and retrieval
  • + Workflows now support agentic flows
  • − Broad surface area is intimidating
  • − Agent story overlaps with LangGraph
