CrewAI

CrewAI is an open-source framework for orchestrating autonomous AI agents that work together as a team (or 'crew'). It provides a structured approach to multi-agent collaboration, where each agent has a defined role, backstory, goal, and set of tools, and agents coordinate to complete complex tasks.

CrewAI's design philosophy centers on role-based agent design and process-driven collaboration. Developers can define sequential or hierarchical workflows where specialized agents (researcher, writer, critic, etc.) pass work products to one another, mimicking how human teams operate.

In the agent orchestration landscape, CrewAI offers a higher-level abstraction than frameworks like LangChain, making it accessible to developers who want to build multi-agent systems without managing the low-level details of agent communication and state management.
