Strato - Sticky Add to Cart
Keeps the Add to Cart button on screen while shoppers scroll, with the variant picker built in. Installs in about a minute, no theme code to edit.
More coming
Every Strato app shares the same rules: one job, done well, and a storefront that stays fast.
How we build
Speed is a feature, not a setting
Anything we add to your storefront is plain HTML, CSS and JavaScript. No frameworks shipped to your shoppers. Shopify allows apps to cost a store up to 10 points of page-speed score; we treat that as a ceiling we should never come close to, not a budget to spend.
Your theme stays yours
Our apps install as theme app blocks, which means you add and remove them from the Shopify theme editor like any other section. We never inject code into your theme files, so uninstalling leaves nothing behind.
We collect as little as possible
Strato - Sticky Add to Cart runs entirely in the shopper's browser. It has no server and no database, and it does not collect personal information about your customers. The full detail is in our privacy policy.
