# Proa

> Proa is a design and experimentation platform for Shopify stores, built by Vasta.

Proa's modules:

- **Proa Studio**: Generates on-brand pages: it distills brand guidelines from your live site and turns briefs, live sites and Figma files into publishable page designs.
- **Proa Experiments**: Ships and measures changes: A/B tests of page changes, Shopify theme templates, split URL tests and campaign landings, with revenue attribution, checkout funnel measurement through the Proa Shopify app, Bayesian and frequentist reads side by side, precise targeting, real-page preview and instant rollback.
- **Proa Insights**: Audits a Shopify store from homepage to checkout against guidelines distilled from a decade of agency store reviews, producing ranked, evidence-backed suggestions. Not self-serve yet: audits are run with the Proa team and human-reviewed.
- **Proa Offer Engine**: One-click post-purchase upsell funnels for Shopify: offers appear right after payment, so the original sale is never at risk. The one Proa module already in production (previously known as OfferEngine), with built-in A/B testing, smart triggers and multi-currency support.
- **Proa Runtime script**: The single script a store installs. It delivers exactly the version the merchant approved and published, supports preview mode and a kill switch, and sets no third-party tracking cookies.
