LangGraph vs CrewAI vs AutoGen: Agent Framework Comparison
All three frameworks let you build multi-step agents, but they optimize for different mental models: LangGraph for explicit stateful graphs, CrewAI for role-based crews, AutoGen for conversational multi-agent orchestration.
Last reviewed:
What we're comparing
- LangGraph
LangChain-authored library for building agents as explicit stateful graphs with persistent memory.
- CrewAI
Role-based framework where agents are "crew members" with defined roles/goals collaborating on tasks.
- AutoGen
Microsoft Research framework for conversational multi-agent systems with configurable turn-taking.
Side-by-side
| Attribute | LangGraph | CrewAI | AutoGen |
|---|---|---|---|
| Mental model | State machine / DAG | Role-playing crew | Chat between agents |
| Control flow | Explicit edges, conditional routing | Sequential or hierarchical | Turn-based conversation |
| State persistence | First-class checkpointing | Task-scoped | Message history |
| Observability | LangSmith integration | Built-in telemetry | Custom logging required |
| Learning curve | Steep | Gentle | Medium |
| Lock-in | Tied to LangChain ecosystem | Standalone | Standalone; heavy MS ecosystem tilt |
When to use which
- Use LangGraph
Production systems that need explicit control flow, checkpointing, and mature tracing.
- Use CrewAI
Rapid prototyping and clear role decomposition (researcher, writer, reviewer).
- Use AutoGen
Conversational multi-agent research or Microsoft-heavy stack integration.
FAQs
Which is most production-ready?
