About LangSmith
LangSmith is designed for teams building with LLMs and agents that need to move beyond ad hoc prompt testing. It brings together traces, datasets, experiments, evaluations, and production monitoring so teams can improve reliability before and after launch.
It is especially useful when prompt quality, tool-calling behavior, and agent outcomes need to be measured across iterations instead of treated as a black box.
