LangSmith provides the tools developers need to move LLM applications from prototype to production with confidence — tracing every LLM call, prompt, and tool use for debugging; running automated evaluations to catch regressions; and monitoring production performance over time. It integrates natively with LangChain but works with any LLM framework. Teams that have struggled with the opacity of LLM behavior in production use LangSmith to understand exactly what their system is doing and why.
