It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry. The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes. The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment. **Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host. - **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable. - **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets. - **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping. - **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure. - **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data. **Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs **Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application [Profile (Markdown)](https://openaitools.app/tool/arize-com.md) ## Snowglobe Snowglobe is built for teams that ship conversational AI and need evidence that their agents behave well in the real world. Instead of hand-writing test conversations one by one, you connect your agent through an API or SDK, configure personas, scenarios and conversation counts, and let Snowglobe run thousands of realistic dialogues automatically. Because the simulated users vary in intent, tone, goals and even adversarial strategies, coverage goes far beyond what a small QA team can script by hand. After a run, Snowglobe produces a detailed report that surfaces failure patterns, edge cases and performance differences across user types. The same runs double as training data: you can export judge-labeled datasets for evaluation pipelines, preference pairs for DPO or reward models, and critique-and-revise triples for supervised fine-tuning, all as clean JSONL. That makes it a single environment for both quality assurance and data generation. The platform is used by organizations including Masterclass, Changi Airport Group, AI Verify (IMDA, Singapore), Meta safety evaluations and Stanford's Legal Innovation through Frontier Technology Lab for risk assessment and regression testing. Snowglobe now lives under Guardrails AI, the broader AI reliability platform. **Pricing & Plans:** Snowglobe is offered as a commercial product under Guardrails AI with plans that include a free tier and paid/enterprise options. Exact pricing is not published on the site, so you need to contact the team for a quote. - **Realistic persona simulation:** Deploy diverse synthetic users with varied intents, tones, goals and interaction styles to mirror real-world behavior. - **Conversations at scale:** Run hundreds or thousands of multi-turn conversations in minutes instead of scripting them by hand. - **Judge-labeled datasets:** Export evaluation sets with judge labels to feed your existing evaluation tooling and catch regressions. - **Fine-tuning data generation:** Produce preference pairs for DPO or reward models and critique-and-revise triples for SFT as clean JSONL. - **Failure and risk reporting:** Get reports that highlight hallucination, toxicity, edge cases and error-rate trends across user types. **Strengths:** Turns testing into automated, high-coverage simulation instead of manual scripting; Same runs produce both evaluation datasets and fine-tuning data; Used and cited by recognizable enterprises and public-sector AI safety programs; Integrates with agents through API or SDK **Limitations:** Pricing is not published and requires contacting sales; Now folded into Guardrails AI, so the standalone Snowglobe brand is less prominent; Best value requires existing evaluation and training pipelines to consume the exported data [Profile (Markdown)](https://openaitools.app/tool/snowglobe.md) ## Frequently Asked Questions ### How do Arize AI and Snowglobe compare in monthly traffic?
