Does Arize AI charge per user?

Are these Arize AI prices current?

They are what the catalogue entry holds, refreshed when the entry is. Vendors change pricing without notice and nobody at Softwr re-verifies each tier by hand, so treat this as a structured summary and the vendor's own pricing page as the authority.

Arize AI pricing

Arize AI plans, side by side

Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.

Arize AI pricing tiers
Plan	Price	Features listed	Step up from the tier below
AX Free	Free	4	Entry tier
AX Pro	$50/month	4	+$50/month, 4 more features
AX Enterprise	On request	4	Priced on request

What each tier adds

The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

What the product covers

The full Arize AI feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.

core

End-to-end tracing
Prompt testing and improvement
Alyx AI engineering agent

analytics

Evaluation framework
Custom dashboards

integration

Data warehouse integrations

People bring Arize AI in for tracing and debugging production ai agents, running large-scale evaluations across traces and sessions, improving prompts before production rollout, storing and querying genai traces alongside a data warehouse. If that is not the job you are buying for, the alternatives to Arize AI are worth a look before you commit to a tier.

How that compares in AI

Too few ai tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the Arize AI badges page.

Before you pay for Arize AI

Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.

What it can tell you is the shape of the ladder: 3 tiers between Free and On request, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.

Arize AI runs on web, api, and is published by Arize AI, Inc.. The full record is on the Arize AI review, and the rest of the category is under best ai tools.
