Overview
Arthur provides tools for monitoring, evaluating, and governing AI applications. Its documentation covers model and agent observability, agent discovery, alerts, policy workflows, and analytics.
Teams can instrument AI applications through SDKs and integrations, then inspect traces and metrics in the platform. Arthur also documents discovery connectors that draw agent information from cloud platforms, employee endpoints, and security telemetry systems.
Arthur AI Decision Snapshot
A quick way to understand who this product may suit, where its limits matter, and which facts are most relevant before you compare alternatives.
Best suited to
Organizations that need a shared inventory, observability, evaluation, and governance workflows for production AI models or agents.
Look elsewhere if
Teams seeking only a lightweight open-source tracing tool may prefer a self-managed product such as Arize Phoenix or Langfuse, which publish open-source deployment options, and should evaluate alternatives such as LangSmith or Arize Phoenix instead.
