# CrewAI

> A Python framework for orchestrating role-playing AI agents as collaborating 'crews', plus event-driven flows.

CrewAI orchestrates multiple agents as a 'crew' with roles, goals, and tasks — a high-level, fast-to-start abstraction for collaborative multi-agent work. It also offers Flows for event-driven, more deterministic control when you need it. Standalone and independent of LangChain.

CrewAI is a Python framework for building multi-agent systems around an intuitive metaphor: a **crew** of agents, each with a role, a goal, and a backstory, working through tasks toward a shared objective. That high-level abstraction makes it one of the fastest ways to stand up collaborative multi-agent workflows — you describe who does what, and CrewAI handles the coordination.

It is aimed at developers who want role-based multi-agent orchestration without wiring a state graph by hand. For cases that need tighter, event-driven control, CrewAI also provides **Flows**, a more deterministic execution model you can combine with crews.

## Highlights

- **Roles, tasks, crews** — define agents by role and goal, assign tasks, and let the crew collaborate (sequential or hierarchical processes).
- **Flows** — event-driven orchestration for deterministic, branching control when autonomy isn't what you want.
- **Tools & integrations** — give agents tools (search, code, custom functions) and connect external systems.
- **Standalone** — built independently of LangChain, with its own lean core.
- **Memory & delegation** — agents can retain context and delegate subtasks to one another.

## In an AI-assisted workflow

```python
from crewai import Agent, Task, Crew

researcher = Agent(role="Researcher", goal="Find sources", backstory="...")
writer = Agent(role="Writer", goal="Draft the brief", backstory="...")
crew = Crew(agents=[researcher, writer], tasks=[research_task, write_task])
crew.kickoff()
```

> [!TIP]
> CrewAI is great for getting a collaborative multi-agent prototype running fast. If you later need explicit state, checkpointing, and resumability, compare [LangGraph](/tools/langgraph) — and use Flows when you want determinism over agent autonomy.

## Good to know

CrewAI is open source (MIT) and free to self-host; a commercial enterprise platform adds hosted deployment, monitoring, and management. You bring your own model provider. See [Which Agent Framework in 2026?](/guides/concepts/agent-frameworks-2026) for where it fits versus the alternatives.
