Shopify apps

Fast stores. No exceptions.

Strato apps run on your storefront as native theme extensions — no injected scripts, no framework loading in front of your shoppers. Features live in the admin, where they cost your customers nothing.

Our apps

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 follows the same rule: whatever it does for you, it costs your shoppers nothing in speed.

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 extensions, which means you switch them on and off from the Shopify theme editor. 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.
