Galileo review
A mature evaluation platform spanning offline testing, production tracing, and runtime controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Galileo is an AI evaluation and observability platform for developers and enterprise AI teams. It covers LLM and agent workflows, RAG applications, prompts, datasets, and model outputs through offline evaluation runs, production tracing, custom evaluators, human feedback, safety and security checks, and runtime guardrails. Its web, API, and self-hosted availability suits teams that need evaluation to continue from development into production.
Evaluation depth is a central strength. Teams can create custom metrics and evaluators, use LLM-as-a-judge evaluation, compare prompts, datasets, and metrics against expected outputs, and add human annotations and feedback workflows. CI/CD evaluation gates and regression testing support release controls, while runtime guardrails can block risky outputs. Integrations include LangChain, LangGraph, OpenAI, OpenAI Agents SDK, CrewAI, Google ADK, Microsoft Agent Framework, Strands Agents, Vercel AI SDK, A2A Protocol, OpenTelemetry, and OpenInference.
The Free plan costs $0 per month and includes 5,000 traces per month, unlimited users, and unlimited custom evals. Pro costs $100 per month with annual billing, includes 50,000 traces per month, standard RBAC, advanced analytics and insights, and dedicated Slack support. Enterprise adds unlimited traces, custom rate limits, hosted, VPC, or on-premises deployment, enterprise-grade security RBAC and SSO, real-time guardrails, and 24/7 support. Galileo fits organizations that want broad evaluation and control capabilities; teams needing only a narrow evaluation workflow may prefer a simpler tool.
