LangGraph vs OpenAI Agents SDK vs CrewAI
Start with the OpenAI Agents SDK for the simplest path to a production agent. Move to LangGraph when you need complex, stateful control flow and strong tracing, and choose CrewAI if a role-based 'crew' of agents matches how you think about the problem.
The verdict
First production agent, keep it simple
Complex branching, durable state, tracing
Role-based multi-agent teams
→ CrewAI

| Our take | A mature, widely used choice for complex, stateful agents with explicit control flow, plus the best observability story via LangSmith. More concepts to learn than lighter SDKs. | The simplest way to ship a real agent: a small set of primitives (agents, tools, handoffs, guardrails) and it works with other model providers too. Start here unless you need complex graphs. | An open-source Python framework for role-based agent teams ('crews') and event-driven flows, with a hosted platform on top. Approachable mental model for multi-agent setups. |

FAQ
Are these frameworks free?
Yes, all three are open source (MIT). You pay for model usage and, optionally, for hosted platforms.
