Products, side by side
Hand-checked pairing
Arize AI
Platform
AI observability platform that traces, evaluates and monitors machine-learning and LLM applications in production, surfacing issues and root causes.
Galileo
Platform
AI evaluation and observability platform: automated evals, real-time guardrails, and production monitoring across the agent development lifecycle.
No counterpart
Arize AI sells these in a stack layer with no product recorded for Galileo yet — nothing on the other side to compare them against.
AI agent
AI engineering agent built into Arize AX that reads a project's traces, prompts, datasets and evals and acts on them — investigating issues, improving prompts and running evaluations from a full-page or side-chat surface whose context carries across pages.
Developer tool
Open-source platform for tracing, evaluating and experimenting with LLM and agent applications, run locally, via Docker/Kubernetes, or as free Phoenix Cloud instances.
Infrastructure service
An AI-native datastore (built on Apache Iceberg) that unifies observability and evaluation data in open formats for zero-copy access across the AI/data stack.
Galileo sells these in a stack layer with no product recorded for Arize AI yet — nothing on the other side to compare them against.
API service
Real-time monitoring layer within the Galileo platform that computes evaluation metrics (hallucination, groundedness, tone) as signals on live production traffic, feeding alerts and dashboards.
