What is CrewAI?
CrewAI is an open-source Python framework for building teams of AI agents that collaborate on tasks through role-based workflows. It is two products: (1) a free, self-hosted open-source framework for defining agents with roles, goals, and backstories, then orchestrating them through tasks; and (2) AMP (Agent Management Platform), a paid cloud platform adding visual Studio, deployment infrastructure, tracing, guardrails, and enterprise features. As of v1.14, CrewAI removed its LangChain dependency and is fully standalone.

Pros & Cons
What works
- Fastest prototyping — idea to working crew in under an hour
- 40K+ GitHub stars — largest multi-agent community
- Fully open source — free, no limits, self-hosted
- Standalone — no LangChain dependency as of v1.14
Watch out for
- High token consumption — multi-agent systems are chatty
- Limited observability (open source) — debugging failures is hard
- Speed issues — complex crews take minutes per execution
- Hierarchical process bugs — circular delegation, off-topic tangents
