FAQ

Questions LangSmith owners ask.

    What is LangSmith and why do I need it?

    LangSmith is the 'Datadog for LLM applications'. Without observability, AI agents in production are black boxes. you can't see what they're doing, why they fail, or how much they cost. LangSmith traces every LLM call, chain execution, and capability use, giving you complete visibility into inputs, outputs, latency, token usage, and error rates.

  • 02

    Does LangSmith work only with LangChain?

    No! While LangSmith is built by the LangChain team and has native LangChain/LangGraph integration, it works with any LLM application. You can trace OpenAI, Anthropic, or any LLM provider directly using the REST API. It also integrates with CrewAI, AutoGen, and other frameworks.
