LangSmith

LangSmith is the LangChain team's agent engineering platform. It records full traces of LLM calls and agent runs so developers can pinpoint issues and compare versions. It offers datasets and automated evals, human annotation, prompt management, and online monitoring with alerts, and can deploy LangGraph agents; it works with or without the LangChain framework. For teams taking AI apps and agents from prototype to production.
