How to choose
For applications that combine retrieval, tools and detailed control, evaluate LangChain's components and integrations. For prototypes centered on role-based multi-agent work, evaluate CrewAI's task model. They are not mutually exclusive; build the same small workflow in both and compare debugging, observability and deployment needs.
