What Galileo is

Galileo is an observability, evaluation, and guardrail platform for generative AI and agentic applications. It offers ready-made evaluations for RAG, agents, safety, and security, as well as custom evaluators. Its observability tools analyze agent behavior to surface patterns and failure modes and suggest fixes. Galileo Experiments lets teams evaluate datasets and prompts systematically and compare results. Evaluation scores can inform agent actions, tool access, and escalation paths. Developers can use Python or TypeScript SDKs or the API, with documented integrations including CrewAI, Google ADK, LangChain and LangGraph, OpenAI, Microsoft Agent Framework, Strands Agents, and Vercel AI SDK. Deployment options are SaaS, Virtual Private Cloud, and on-premises. The Free plan includes 5,000 traces per month, unlimited users, and unlimited custom evaluations. Pro costs $100 a month, billed yearly, for 50,000 monthly traces; pricing scales with trace volume. SSO supports OIDC and SAML only on a customer's own Galileo cluster, not the free version or hosted app.galileo.ai service.
