About
LangSmith is a platform for LLM observability, tracing, evaluation, and monitoring from the LangChain team — framework-agnostic, works with or without LangChain.
Why it made the leaderboard
It gives full-stack tracing, evals, and monitoring for LLM apps and agents — framework-agnostic despite the LangChain name — so you can debug a failing chain and watch cost and latency in production.
