Stop shipping on faith
Most store changes go live and are declared a success because nobody complained. Proa Experiments turns every change into a question with an answer: which version sells more, measured in orders on your own store.

How an experiment runs
Pick the kind of test
A change on a page — a hero, a headline, a whole page generated by Studio. One theme template against another. One page of the store against another. Or one test per ad campaign.
Ship it as a variant
Published through the Runtime script in seconds. No theme deploy, no maintenance window.
Visitors split, orders decide
Each version is measured against the original in orders and revenue, currency by currency.
Keep the winner
Promote the version that converts — by hand, or automatically once the result is decisive — and start the next question.
Built for decisions you can defend
Measured in revenue, not clicks
Variants are compared by what decides: orders and revenue per version, attributed through your store's own purchase flow. Clicks are an opinion; the register is a fact.
Targeted precisely
Choose exactly who enters a test and where: pages included and excluded, screen size, schedule. Experiments that would collide are refused by name, and grouped tests never share a visitor. The rest of the store stays untouched.
Previewed on the real store
See any variant on your own storefront, in your own browser, before a single visitor does. No staging theme, no guesswork.
Reversible in one click
Every experiment keeps a point of return. Roll a variant back, or stop everything, and your visitors see the change in under a minute.
Honest reads
Two independent statistical reads — Bayesian and classical — side by side, a duration estimate before you start, and a report that says when there is enough data for a decision and when there is not. We would rather you wait than win a coin flip.
However you work
No developer? We operate the experiments with you. Agency-run or in-house team? They get the same dashboard, and the only technical step is one script tag, once.
What to expect, honestly
Installation is one script tag — or, on Shopify, the Proa app with no code at all — and a first experiment can be live the same week. The read takes as long as your traffic takes: stores with heavy traffic get answers in days, smaller stores in weeks, and we will tell you which case you are in before you start, not after. During the alpha we run the first experiments with you.
Curious how the delivery works under the hood? The Runtime script page explains the guarantees: no flicker, no speed hit, no theme deploys, reversible always. And the Experiments docs cover the details: test types, traffic splitting, targeting, and how to read the results.
What would you test first?
Bring the page you have been arguing about. We'll show you how the argument ends.
