CrewAI is an open-source framework for building systems of collaborating AI agents and structured agent workflows. Developers can define specialized agents with roles, goals, tools, and tasks, then organize them into crews or more explicit flows that coordinate how work moves from one step to another. The framework is intended for business automation and production applications where a complex objective benefits from several focused agents rather than one general-purpose prompt.

CrewAI supports integrations with language models, tools, memory, knowledge sources, observability, and human input, while its flow layer provides more deterministic control over state and execution. Common use cases include research, content generation, analysis, customer operations, and internal process automation. It is best suited to developers who want a Python-based orchestration layer that combines autonomous agent behavior with enough workflow structure to make multi-step systems easier to manage and deploy.
