What is CrewAI?
CrewAI is an open-source Python framework for building "crews" of AI agents, each with a defined role, that collaborate on a shared task — a researcher agent, a writer agent, and a reviewer agent working in sequence, for example.
Key features
- Role-based agent definitions (goal, backstory, tools)
- Sequential and hierarchical task orchestration between agents
- Works with most major LLM providers
- Open-source core with an optional hosted enterprise platform
- Built-in tool integrations for common agent actions
Pros
- Genuinely popular open-source option with an active community
- Role-based design makes complex multi-agent logic easier to reason about
- Free core framework with no vendor lock-in
Cons
- Requires real Python development skill, not a no-code tool
- Debugging multi-agent failures can be genuinely difficult
- Documentation moves fast and occasionally lags behind new releases
