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

Portkey provides an AI gateway with caching, fallbacks, load balancing, guardrails, and observability for LLM applications. Production reliability for AI apps.
Reviewer scorecard
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“The gateway approach adds caching, fallbacks, and guardrails without code changes. Production AI apps need this layer.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“Reliability features — caching, retries, fallbacks — are table stakes for production AI. Portkey makes them easy.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
“AI gateways will be standard infrastructure. Portkey's focus on reliability and guardrails addresses real production needs.”
