Frequently Asked Questions
CrewAI vs OpenAI Agents SDK: which should you choose?
If you're a Python developer prototyping multi-agent workflows with OpenAI and want a free, lightweight SDK with sandbox agents and realtime voice, choose OpenAI Agents SDK. For enterprise teams that need governance, discovery, cost tracking, and a path from no-code to production at scale, CrewAI is the clear winner — especially given its inclusion in the OWASP security guide and active development on token optimization.
Which tool is free?
OpenAI Agents SDK is completely free (MIT license). CrewAI has a free tier but advanced features require enterprise pricing.
Do both support human-in-the-loop?
Yes, both have human-in-the-loop mechanisms, but CrewAI provides more structured approval gates with RBAC.
Can I use non-OpenAI models with these tools?
OpenAI Agents SDK supports 100+ models via LiteLLM integration. CrewAI supports multi-LLM testing and model swapping.
Which tool is better for compliance?
CrewAI, with RBAC, immutable audit trails, and runtime PII redaction hooks. It's also included in OWASP's agent security guide.
Does OpenAI Agents SDK have a no-code editor?
No, it's a code-first Python SDK. CrewAI offers a no-code visual editor with an AI copilot.
Can I build voice assistants with CrewAI?
CrewAI does not mention realtime voice; OpenAI Agents SDK has Realtime Agents with gpt-realtime-2 for voice.
Which tool is used by Fortune 500 companies?
CrewAI reports 63% of Fortune 500 use it. OpenAI Agents SDK is newer and not as widely adopted in enterprise.
What recent security updates have there been?
CrewAI was included in the OWASP Agentic Security Initiative Top guide (Jun 2026). No recent security news for OpenAI Agents SDK.
