The framework landscape and how to choose

Learn what each framework is good at: LangGraph (graphs with state, loops, human approval — our main tool), CrewAI (role-based teams of agents, quick to start — used in Project 4), AutoGen / Microsoft Agent Framework (agents talking to each other), OpenAI Agents SDK and Claude Agent SDK (light, provider-made), LlamaIndex (agents over documents). Choose by: control needed, multi-agent needs, team skills, production features (state, tracing, deployment).
