// why it matters

Built to move the metric you actually care about.

Benefit 01

Always-visible CTA

The Add to Cart button follows shoppers down the page — no scroll-back required.

Benefit 02

Mobile first

Pinned to the bottom on mobile, non-intrusive on desktop. Tested across iOS Safari, Chrome, and in-app browsers.

Benefit 03

Smart visibility

Hides when the main ATC button is in view, reappears on scroll — no duplicate noise.

// use cases

When to reach for this.

01

Long product pages

Rich PDPs with scroll-heavy content — keep the action button accessible.

02

Mobile-heavy traffic

Essential when mobile is 60%+ of sessions. Thumb-reachable CTA wins.

03

High-consideration products

Fashion, furniture, tech — customers scroll through gallery, reviews, specs. Sticky ATC converts at the decision moment.

// how it works

The build.

Persistent ATC bar that follows the user on scroll — reduces friction and captures impulse purchases on mobile.

  • Configurable. Default is mobile-only since desktop PDPs rarely need it. You can enable desktop globally or per-collection.

  • No. It uses Intersection Observer to hide automatically when the main ATC is visible — no double-render, no visual clash.

  • Clicking the sticky ATC respects the currently selected variant. If no variant is selected, it scrolls to the selector and highlights it.
