LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.
Reviewer scorecard
“Most flexible multi-agent framework. The conversation-based approach is more natural than rigid workflows.”
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“Academic project energy — impressive demos but rough edges in production. Microsoft's commitment level is unclear.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“Microsoft Research backing and enterprise integration path make it the safe bet for enterprise multi-agent systems.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
