Zero flicker, because there's nothing to hide
The redirect happens before the page paints. No anti-flicker snippet, no blanked screen, no flash.
True server-side A/B testing by URL
Redirect, don't repaint.
A/B test your Shopify pages by URL. The variant is chosen server-side and the visitor is redirected before a pixel paints: zero flicker, zero speed cost, no theme code.
Shopify App Store link will go live after approval.
Why server-side wins
If an A/B app needs an anti-flicker setting, it still flickers.
ServerSideSplitter avoids the browser-side test script entirely. Merchants build pages in Shopify, paste URLs, split traffic, and compare variants by real revenue.
Zero page-speed cost
No experiment JavaScript loads on your storefront, so LCP and Core Web Vitals stay exactly where they are.
True server-side split testing, by URL
Build pages in Shopify, paste the URLs, split across up to 5 weighted variants, and compare by dollars per visitor.
How it works
One storefront URL. A true redirect underneath.
Point one proxy URL at the Shopify pages you already built. ServerSideSplitter handles assignment, sticky visitors, conversion attribution, and revenue reporting.
