Galileo

Evaluation and observability platform for GenAI applications and agents

As of 29 August 2026, Galileo has a free plan and paid plans start at $100/month. Enterprise platform to evaluate, monitor, and protect generative AI applications and agents in production. Softwr lists it under AI. Galileo is available on Web, API.

Overview

What Galileo does

Galileo is a GenAI evaluation and observability platform that helps teams evaluate, monitor, and protect AI applications and agents at enterprise scale. It captures ground truth from synthetic, development, and production data, offers pre-built evaluations for RAG, agents, safety, and security, distills LLM-as-judge evaluators into compact models for cost-effective monitoring, and converts offline evaluations into production guardrails.

What people use it for

  • Evaluating RAG and agent applications before production release
  • Monitoring live GenAI applications for failures and drift
  • Applying real-time guardrails without custom integration work
  • Reducing evaluation costs using distilled Luna judge models

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Galileo.

  • The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
  • Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
  • Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
  • On-premises deployment requires an Enterprise contract rather than being available self-serve.
