LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.

LiteLLM provides a unified OpenAI-compatible proxy for 100+ LLM providers. Load balancing, fallbacks, spend tracking, and rate limiting in one layer.
Reviewer scorecard
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“One proxy for every LLM provider with OpenAI-compatible API. Load balancing and fallback routing are production essentials.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“If you use multiple LLM providers, LiteLLM eliminates the integration complexity. Spend tracking across providers is invaluable.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
“Multi-model architectures need a proxy layer. LiteLLM is becoming the standard infrastructure for LLM routing.”
