Licence unstated as a software licence: Arize AX is a commercial product and the vendor publishes no software licence for it — the pricing page documents it as a paid/free-tier service delivered SaaS (Free, Pro) or self-hosted (Enterprise). No AX terms-of-service page was found on arize.com at the URLs checked (arize.com/terms-of-use/ and arize.com/terms/ both returned HTTP 404, 22 August 2026). Source, checked
Self-host partial: AX Free and AX Pro are SaaS only; self-hosted deployment is offered on AX Enterprise Source, checked
OpenTelemetry yes — Arize AX ingests OpenTelemetry traces; the vendor ships an arize-otel package wrapping OTel primitives and publishes GRPC/HTTPS OTLP endpoints (incl. an EU endpoint) Source, checked
Free tier limits AX Free: 25k trace spans per month, 1 GB ingestion volume per month, 15 days retention, SaaS deployment, unlimited users, unlimited evals Source, checked
Price per 100k traces not trace-denominated and no unit rate published: AX Free $0 (25k spans + 1 GB per month), AX Pro $50 per month including 50k trace spans and 10 GB, AX Enterprise Custom. No per-span overage or top-up price is published on the pricing page or on the vendor's pricing-and-usage doc, and Pro is capped at 50k spans per month, so no honest price per 100k traces (or per 100k spans) can be derived; a trace also contains many spans. Currency is shown only as "$", never named. Source, checked
Data residency US or EU or CA (listed as the Data region on all three tiers) Source, checked
Retention AX Free: 15 days; AX Pro: 30 days; AX Enterprise: Custom. The vendor's pricing-and-usage doc (https://arize.com/docs/ax/security-and-settings/pricing-and-usage, read 2026-08-22) adds an extended-retention option for Pro: "Eligible AX Pro users can add 13-month data retention without changing to a different base plan."

Assessment

Arize publishes no software licence for AX; the pricing page documents it as a paid service, SaaS on Free and Pro and SaaS or self-hosted on Enterprise (22 August 2026). No AX terms-of-service page was found at the URLs checked.

Ingestion is OpenTelemetry-based: an arize-otel package wraps OTel primitives, and OTLP endpoints are published over gRPC and HTTPS, including an EU endpoint. First-party SDKs cover Python and TypeScript/JavaScript; Java arrives through agent-framework integrations (Arconia, LangChain4j, Spring AI).

Metering is denominated in trace spans plus an ingestion cap, never in traces. Free includes 25k spans and 1 GB a month at 15 days retention; Pro is $50 a month for 50k spans and 10 GB at 30 days, with a 13-month retention option; Enterprise is custom. No per-span overage rate is published and Pro is capped at 50k spans, so no price per 100k traces can be derived. The data region is US, EU or CA on all three tiers. AX carries no version numbers; its newest changelog entry is dated 19 August 2026.

A site-wide banner links the vendor's August 2026 announcement of a signed definitive agreement for Dynatrace to acquire Arize. It states a signed agreement, not a completed deal, and publishes no change to AX availability, pricing or support.
