CrewAI

Role-based multi-agent framework where agents collaborate as a crew.

CrewAI is a Python framework for orchestrating role-playing autonomous agents. You define each agent's role, goal, and backstory, then assemble them into a crew with tasks; the framework infers coordination. It supports both sequential and hierarchical processes and has a large community following. CrewAI Enterprise adds a hosted control plane, monitoring, and deployment tooling.
