LangChain
The most popular open-source framework for building LLM-powered apps with chains, agents, and RAG
About LangChain
LangChain is the most widely adopted open-source framework for building applications powered by large language models. It provides composable components for building chains (sequences of LLM calls), agents (LLMs that use tools), and RAG pipelines (combining retrieval with generation). LangChain connects to 100+ LLMs, vector stores, and data sources through a unified interface, dramatically reducing the boilerplate of building AI applications.
Key Features of LangChain
