Galileo

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.

Galileo publishes 8 APIs on the APIs.io network, including Annotations API, ApiKeys API, Auth API, and 5 more. Tagged areas include AI Evaluation, AI Observability, GenAI, Guardrails, and Agentic AI.

The Galileo catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Galileo’s developer surface includes authentication, documentation, API reference, pricing, engineering blog, and 12 more developer resources.
