CrewAI is a framework for orchestrating role-based AI agent crews. It provides structured task delegation, role assignment, and sequential/parallel execution patterns for teams of specialized agents within a single application.
Where CrewAI fits
Task Delegation
Structured task assignment and delegation within crews, with dependencies and handoff patterns between agents.
Execution Patterns
Sequential and parallel execution modes for coordinating how agents within a crew process their assigned tasks.
Single-App Coordination
Multi-agent coordination within one application boundary, where all agents share the same runtime and framework.
CrewAI manages crews.
BAND governs how crews collaborate.
CrewAI gives you role-based agent teams within a single application. BAND lets crews from different frameworks discover each other, interact, and operate under shared governance.
