1# CrewAI - Multi-Agent Orchestration Framework
2 
3Build teams of autonomous AI agents that collaborate to solve complex tasks.
4 
5## When to use CrewAI
6 
7**Use CrewAI when:**
8- Building multi-agent systems with specialized roles
9- Need autonomous collaboration between agents
10- Want role-based task delegation (researcher, writer, analyst)
11- Require sequential or hierarchical process execution
12- Building production workflows with memory and observability
13- Need simpler setup than LangChain/LangGraph
14 
15**Key features:**
16- **Standalone**: No LangChain dependencies, lean footprint
17- **Role-based**: Agents have roles, goals, and backstories
18- **Dual paradigm**: Crews (autonomous) + Flows (event-driven)
19- **50+ tools**: Web scraping, search, databases, AI services
20- **Memory**: Short-term, long-term, and entity memory
21- **Production-ready**: Tracing, enterprise features
22 
23**Use alternatives instead:**
24- **LangChain**: General-purpose LLM apps, RAG pipelines
25- **LangGraph**: Complex stateful workflows with cycles
26- **AutoGen**: Microsoft ecosystem, multi-agent conversations
27- **LlamaIndex**: Document Q&A, knowledge retrieval
