CrewAI

CrewAI is a Python framework that enables developers to create teams of AI agents that collaborate on complex tasks. Unlike single-agent systems, CrewAI lets you define multiple agents with specific roles (researcher, writer, analyst, coder) that work together in structured workflows. Each agent has its own persona, tools, and objectives, and they communicate and delegate tasks to each other autonomously. The framework supports sequential and hierarchical task execution, custom tool integration, and works with any LLM provider. CrewAI is particularly powerful for workflows that naturally involve multiple perspectives or skill sets, such as content creation pipelines, research teams, or software development workflows. The CrewAI Enterprise platform adds a visual builder, deployment infrastructure, and team collaboration features.
