CrewAI gives you multi-agent orchestration without the LangChain baggage. You define agents with roles and goals, chain tasks together, and let them collaborate autonomously on complex workflows. It's built for production use with memory, 50+ built-in tools, and decent observability. The sequential and hierarchical process modes cover most patterns, from simple pipelines to manager-delegated workflows. YAML config keeps things clean when your crews get bigger. If you need specialized AI agents working together rather than a single bot doing everything, this is the straightforward option. Lighter than LangGraph, more structured than rolling your own agent loops.
