What is Shopify SimGym?

Simulated shoppers test your Shopify theme before real ones do.

Who is Shopify SimGym best for?

Shopify SimGym is best for Shopify merchants who want to try a new theme on AI shoppers.

  • Theme redesigns

    It runs AI shoppers on your live theme and a draft theme and names the one with the higher add-to-cart rate.

  • Seasonal and campaign layouts

    You can try a holiday theme or a promotion layout on simulated shoppers before the campaign goes live.

  • Quick storefront audits

    A single-theme run lists strengths, problems and fixes ranked by likely effect on conversion, and can focus on one area such as the cart.

How much does Shopify SimGym cost?

Shopify SimGym is free to install and includes a monthly allowance of simulations; after that, a single-theme simulation costs $0.75 and a theme comparison $1.50, charged on your Shopify bill.
