CrewAI

CrewAI is an open-source multi-agent AI framework created by João Moura, designed to orchestrate autonomous AI agents that collaborate to complete complex tasks. The framework has become one of the most popular tools for building production-ready multi-agent systems.

CrewAI's core concept is organizing AI agents into "crews" — teams of specialized agents with defined roles, goals, and tools that work together on a task. Each agent can be backed by different LLMs and equipped with specific tools (web search, code execution, file operations), while a configurable process (sequential, hierarchical, or parallel) governs how agents collaborate. The framework handles memory, delegation, and task handoffs automatically.

CrewAI differentiates from other agent frameworks (like AG2 and LangGraph) through its emphasis on simplicity and production-readiness. The framework requires minimal boilerplate code to define agents and tasks, making it accessible to developers who want to build multi-agent systems without deep expertise in AI orchestration. CrewAI Enterprise offers managed deployment, monitoring, and governance features for production workloads.
