Agency Swarm: The Org-Chart Framework for Multi-Agent AI
Agency Swarm is the only multi-agent framework that forces you to design an organizational chart before your agents send a single message. Where [CrewAI](/tools/crewai) lets agents chat freely and [LangGraph](/tools/langgraph) gives you a state machine, Agency Swarm makes you define who talks to whom and in what direction. That constraint is the entire point.

CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
