LangChain, CrewAI, or LlamaIndex: Choosing the Right AI Agent Library
The article compares three popular Python libraries for building AI agents in production: LangChain, CrewAI, and LlamaIndex. LangChain offers granular control over prompts and tools, CrewAI simplifies multi-agent orchestration, and LlamaIndex excels at data retrieval from large document collections. All three support major LLM providers and async APIs for FastAPI integration.
