LangSmith Observability is an AI agent observability platform that provides complete visibility into agent behavior by tracing, monitoring, and analyzing executions across popular frameworks and languages (Python, TypeScript, Go, Java). It offers end-to-end tracing, real-time dashboards, cost tracking, online evaluations, and a purpose-built SmithDB that stores and queries large, nested traces, with an option to self-host in your VPC. It integrates with OpenTelemetry and major SDKs, supports alerts via webhooks or PagerDuty, and helps teams diagnose latency, failures, and hallucinations to improve agent quality.
