Test storefront changes safely and ship a winner only when the data supports it.

Holdout runs A/B tests on your storefront without touching theme files. Describe the change you want, preview both versions, choose the audience and the goal, then launch. It measures conversion rate, revenue per visitor, add-to-cart and order value, and applies the winner as a runtime rule you can roll back at any time. Every test is held to a minimum duration and a calibrated threshold. When the data falls short, Holdout says so instead of naming a winner.

Really useful tool for improving our Shopify store. The testing process is simple, and the performance metrics make it easier to understand what actually works. I also like being able to roll back experiments when needed. Highly recommended!

Great experience with Holdout. The fact that tests run without changing the theme gives us confidence when experimenting with different storefront ideas.

A very useful testing solution for Shopify. I particularly like being able to preview both versions, select the audience and define the conversion goal before launching a test.
