CrewAI vs AutoGen
You are picking between the two most popular multi-agent frameworks in Python. CrewAI is role-based and friendlier; AutoGen is conversation-based and Microsoft-backed.
CrewAI
OSS framework for orchestrating role-playing AI agents that collaborate on complex tasks — Python-first.

AutoGen
Microsoft's open-source multi-agent framework — conversation-driven orchestration with deep Azure / OpenAI integration.
Read review →Our take
For most teams prototyping multi-agent systems, CrewAI. The mental model is friendlier and observability is easier to reason about. For Azure-first shops or teams that want Microsoft as the long-term maintainer, AutoGen. Both burn tokens fast on multi-agent loops 鈥?budget for it. Honest answer for production: stay single-agent with LangChain or LangGraph until multi-agent is genuinely required.
