About CrewAI
CrewAI is an open-source Python framework for orchestrating role-playing, autonomous AI agents. It provides high-level abstractions and low-level APIs for building production-ready multi-agent workflows. The framework supports two primary modes: Crews for optimizing autonomy and collaborative intelligence with role-based agents, and Flows for event-driven automations that combine precise workflow control with single LLM calls. CrewAI is rapidly becoming the standard for production-ready agentic automation, with over 100,000 developers certified through community courses. The framework integrates with various LLM models and allows for flexible task delegation and collaboration among agents.
