Galileo vs WhyLabs

Galileo is an AI observability and evaluation engineering platform that helps enterprise teams evaluate, monitor, and protect generative AI applications and agents at scale. Its Agent Reliability platform enables teams to build ground-truth datasets, auto-tune evaluation metrics from live feedback, distill LLM-as-a-Judge evaluators into compact Luna models for production guardrails, and run the full eval engineering lifecycle from offline testing to production monitoring. The platform is trusted by teams at HP, Comcast, and Twilio, and is deployable as SaaS, VPC, or on-premises.

WhyLabs provided an AI observability platform for monitoring machine learning models, data pipelines, and generative AI applications in real-time. Key differentiators included privacy-preserving data logging via open-source whylogs, LLM monitoring with langkit, drift detection, and low-latency threat detection without data movement. Targeted ML engineers and data scientists at Fortune 100 companies to AI startups in regulated sectors like financial-services and healthcare. Company discontinued commercial operations in 2025 following reported acquisition by Apple, open-sourcing its platform; tools remain available on GitHub.
