CrewAI

by CrewAI Inc

CrewAI is an open-source Python framework for building and orchestrating multi-agent AI systems, modeling agents as role-playing "crew members" each with defined roles, goals, backstories, and tools. It supports sequential and hierarchical task flows, an internal event bus, and async execution, enabling complex collaborative agent pipelines. In December 2024, CrewAI removed its LangChain dependency entirely, repositioning itself as a lean, from-scratch multi-agent framework with a commercial enterprise platform layered on top.
