Galileo (galileo.ai, formerly rungalileo.io) is the GenAI evaluation, observability, and production guardrail platform for LLM and agentic applications. Galileo provides pre-built and custom evaluators, agentic trace and span logging, dataset and experiment management, prompt management, runtime protect (guardrails), and integrations with major LLM providers and agent frameworks. The platform exposes a public REST API plus official Python and TypeScript SDKs and integrates with LangChain, CrewAI, OpenAI Agents, and OpenTelemetry/OpenInference. Galileo is deployable as SaaS, VPC, or on-prem.
