CrewAI is an open-source Python framework that gained popularity in 2024 by modeling agents as a role-based crew, each with a role, a goal, and a backstory; tasks are assigned within the crew. Its intuitive API gives developers a low barrier to entry for building a Multi-agent System. Compared with LangGraph and AutoGen, it is less graph-centric and more focused on the "human-team" metaphor. It's a common choice for content production, research assistants, and operational workflows, and integrates with Tool Use and memory components.
