LangChain
The most widely-adopted framework for building LLM-powered applications. Provides composable components for chains, agents, retrieval, and memory, plus LangGraph for complex multi-agent orchestration and LangSmith for observability.
Our Take
The Swiss Army knife of LLM application development. LangChain's ecosystem — from the core framework to LangGraph and LangSmith — has become the default starting point for building anything with LLMs beyond simple chat.
