LangChain
Framework for developing LLM-powered applications
LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.
Panel Reviews
The Builder
Developer Perspective
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
The Skeptic
Reality Check
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
The Futurist
Big Picture
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
