About the service
An observability and evaluation platform for LLM applications from the creators of LangChain. It captures traces of chains and agents, lets you inspect every step, build datasets from real runs and run offline evaluations with LLM-as-judge. It works with LangChain and LangGraph but also plugs into arbitrary code via the SDK.
