Everything Free, Nothing Bloated
The features that matter, without the upsell walls
Free Shipping Progress Bar
Show shoppers exactly how far they are from free shipping. Three editable states update live as the cart changes, with an optional progress fill.
Announcement Bar
Run one message or rotate up to five, with per-message links and a close button that remembers each shopper’s choice.
Live Cart Updates
The shipping bar reads the real cart total after discounts and re-renders instantly on add, change, or remove — no page reload.
Scheduling
Set a start and end time for any bar in your store’s timezone. Perfect for sales that begin and end on their own.
Automatic Currency
International shoppers see the free-shipping threshold converted to their presentment currency and formatted for their locale.
No Permissions, No Data
StackBar installs asking for zero access scopes and collects no customer data. Settings live in Shopify app metafields.
Under 8KB
A native Online Store 2.0 app embed with under 8KB of JavaScript and no external requests, so it stays out of your storefront’s way.
Styled to Your Theme
Colors, gradients, fonts, and emoji, with placement top or bottom, sticky or static, and device targeting.
Works Everywhere
Compatible with every Online Store 2.0 theme, on desktop and mobile, and available in 11 languages.
Privacy-First by Design
StackBar requests zero access scopes and collects no customer data.
Your bar settings live in Shopify app metafields, and the storefront makes no external requests. There is nothing to leak because there is nothing collected.
