Multi-Agent Orchestration Frameworks in Production: Comparing LangGraph, AutoGen, CrewAI, and LlamaIndex Workflows
Deploying autonomous multi-agent systems to production exposes the fundamental limitations of single-turn prompting and linear DAG chains. Real-world agent workflows require cyclical execution, durable state persistence across hours or days, reliable human-in-the-loop interrupts, and fault-tolerant error recovery. Four primary frameworks have emerged as the leading orchestration layers in 2026: LangGraph, Microsoft AutoGen, CrewAI, and LlamaIndex Workflows. While each framework enables multi-ag
