CrewAI vs AutoGen vs LangGraph: Which Multi-Agent Framework in 2026?

Three frameworks dominate multi-agent development in 2026. They have fundamentally different design philosophies, and picking the wrong one costs you weeks. Here's the decision guide.

The One-Sentence Summary

CrewAI : Role-based teams. Define agents as crew members with jobs. Fast to build, great for pipelines.

AutoGen / AG2 : Conversation-based. Agents talk to each other. Best for code generation and research.

LangGraph : Graph-based state machines. Explicit control flow. Best for complex production systems.
