CrewAI vs OpenAI Agents SDK
Two approaches to multi-agent AI, open-source CrewAI vs OpenAI's native Agents SDK, compared for enterprise adoption.
| Feature | CrewAI | OpenAI Agents SDK |
|---|---|---|
| Model Support | Any LLM (OpenAI, Anthropic, local) | OpenAI models primarily |
| Architecture | Role-based crews with tasks | Agent handoffs and tool use |
| Open Source | Yes, full source available | Open source SDK, closed models |
| Tool Integration | Custom tools + LangChain tools | Native function calling + MCP |
| Vendor Lock-in | Low, model agnostic | Higher, tied to OpenAI ecosystem |
| Enterprise | CrewAI Enterprise with SSO/RBAC | OpenAI Enterprise agreements |
| Community | Large open-source community | Growing with OpenAI backing |
When to use CrewAI
