## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. 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

## Realyst

Realyst is a browser extension built for people who evaluate single-family homes and want the numbers without leaving the listing page. Once installed, it adds its own analysis layer on top of Zillow.com, so a normal property page also shows a running model of what that home would look like as a rental: rent assumptions, mortgage terms, vacancy allowance, renovation estimates and the resulting return metrics. The pitch is speed — investors and realtors can screen listings far faster than rebuilding a spreadsheet for every address.

The extension leans on a configurable financial model rather than a single canned output. You adjust inputs such as expected rental rate, mortgage rate, vacancy rate and renovation budget, and the cash-on-cash return and ROI figures update to match your assumptions. A neighbourhood comparison view can line up the profitability of up to 80 nearby properties at once, which makes it easier to spot the outliers in a subdivision before scheduling showings. Results can be saved and exported to CSV or PDF for later review or sharing with a partner or client.

Realyst also layers in AI assistance: five GPT-4 powered prompts cover things like renovation estimates and neighbourhood market trends, and homeowners and buyers get a plain-language PDF summary with nearby comparables plus property, neighbourhood and demographic context. A two-day free trial is offered through in-app purchase, and the extension is distributed on the Chrome Web Store.

**Pricing & Plans:** Free two-day trial via in-app purchase; continued use requires a paid subscription (pricing shown in-app).

- **Adjustable financial model:** Tune rental rate, mortgage rate, vacancy rate and renovation estimates to see how each assumption moves cash-on-cash return and ROI.
- **Neighbourhood-level comparison:** Compare the projected profitability of up to 80 nearby single-family properties in a single click to spot the strongest candidates fast.
- **GPT-4 powered insight prompts:** Five built-in AI prompts generate quick takes on renovation costs, market trends and other decision inputs that are awkward to look up manually.
- **Export and reporting:** Save results and export to CSV or PDF, and generate a homeowner/buyer summary that includes comps, neighbourhood and demographic context.
- **Zillow-native workflow:** Everything runs on the listing page you are already viewing, so there is no separate app to open or address to re-enter.

**Strengths:** Analysis appears directly on Zillow, so screening requires almost no extra steps; Inputs such as rent, vacancy and mortgage rate are editable instead of fixed; Neighbourhood comparison over many properties speeds up shortlisting; Exports to CSV and PDF make results easy to share or archive

**Limitations:** Only works on Zillow listings for single-family homes; Insight quality on any given address depends on Zillow's underlying data; Free trial is short and pricing must be checked inside the extension
