CrewAI is a framework for building multi-agent AI systems, where teams of AI agents collaborate on business tasks such as lead enrichment, content generation, customer support, and quality assurance testing. It is built for developers and business teams who want to orchestrate several agents working together rather than relying on a single model, and it is used widely enough that a majority of Fortune 500 companies run workflows on it.
Building with CrewAI follows three steps: defining agents with a role, goal, and backstory along with a chosen model, memory, and tools; defining tasks with a clear description and expected output; and combining agents and tasks into a crew that can include a planning step, a manager agent, or run tasks asynchronously. More than 100,000 contributors have worked on the open-source project, and the platform reports handling hundreds of millions of agentic workflow runs every month.
The core CrewAI framework is open source and free for teams to install and run without restriction. The company also offers an enterprise build-and-runtime platform for organizations that need centralized deployment and governance on top of the open-source foundation.
