Arize AI’s public pricing is straightforward: there is a free entry point, a fixed-price self-serve paid plan, and a custom enterprise tier for larger deployments. The public AX pricing page and docs focus on usage limits rather than seats, so buyers should think in terms of trace spans, ingestion volume, retention, and deployment model instead of per-user packaging. AX Free is positioned for individuals and startups getting started, AX Pro is aimed at small teams that need higher limits and longer retention, and AX Enterprise is reserved for teams that need dedicated support, security compliance, and self-hosting. Startup pricing is also called out publicly, which suggests the company has a separate path for early-stage buyers, but the exact discount is not disclosed. For teams comparing options, the most important decision points are whether the included monthly limits are sufficient and whether the enterprise features justify moving away from the public Pro plan. Because overages on Pro are billed automatically, usage-heavy teams should pay close attention to span and ingestion growth before adopting the plan.
◇ Pricing model
Freemium with usage-based overages on the Pro tier and custom pricing for enterprise. Arize AX has a public free tier, a fixed-price paid tier, and a quote-only tier for larger deployments.
↻ Billing notes
Arize AX publicly shows a monthly Pro price and custom enterprise pricing, while Free is listed as Free. The docs say startup pricing is available and that discounted startup pricing requires a separate application process. The Pro plan’s usage beyond monthly limits is billed automatically, and the product terms tie access to acceptance of the terms and payment of the fees shown on the pricing page. No public annual discount is disclosed in the supplied documents, and no seat minimums are listed.
The free tier is capped at 25k spans per month and 1 GB of ingestion volume per month, with 15 days of retention. The page does not list overages for Free.

Enterprise limits are custom and the page does not publish a standard usage ceiling. Security and support terms include custom SLAs and self-hosted deployment options.
⚠ Arize does not publish a public price for Enterprise, so buyers needing self-hosting, dedicated support, compliance features, or custom SLAs must request a quote. The pricing and usage page says overages on Pro are billed automatically, which means monthly bills can rise when span or data consumption exceeds the included limits. The terms also indicate that accessing the service may require paying the fees set forth on the pricing page, but they do not disclose any extra implementation or onboarding fees publicly.
Yes. The public AX pricing page lists AX Free as Free, and the docs describe it as a plan for individuals and startups getting started with observability and evals. The free tier includes 25k trace spans per month, 1 GB of ingestion volume per month, and 15 days of retention. If you need more usage or longer retention, you would need to move to Pro or Enterprise.
AX Pro is publicly listed at $50 per month. The documentation says that usage beyond the included monthly limits is billed automatically, so the actual monthly bill can be higher than the base subscription price. The public overage rates are $0.0008 per additional span and $3 per additional GB.
No. AX Enterprise is shown as Custom on the public pricing page, and the docs describe it as for enterprises that need dedicated support, security compliance, and self-hosting. Because the price and billing cadence are not publicly disclosed, buyers should expect to request a demo or quote. The page also shows that custom plans can include custom SLAs.
