Wishlist infrastructure, not another widget

Why Wishlist Stack

Not every brand needs another widget.

Fixed wishlist apps fall apart when your team needs headless architecture, custom variant behavior, specific metafields, or pixel-perfect storefront design.

You build the storefront UI. Wishlist Stack stores the data and keeps it hydrated with Shopify product info.

+No vendor UI lock-in or forced theme widget.

+Clean wishlist primitives for lists, groups, items, notes, ordering, and sharing.

+Current product titles, prices, images, and selected metafields without maintaining a separate product cache.

What you get

The backend for every wishlist shape.

A small set of flexible building blocks powers favorites, save-for-later, registries, multiple lists, and public wishlists.

Wishlist primitives

Lists, groups, items, quantities, notes, ordering, and sharing endpoints for custom storefront workflows.

Shopify product context

Return wishlist data with current Shopify titles, variant data, prices, imagery, and selected metafields.

SDKs for modern teams

Use the Universal SDK for custom JavaScript runtimes or the Hydrogen SDK for Shopify Hydrogen storefronts.

Use cases

One foundation. Many customer experiences.

Because Wishlist Stack does not prescribe the storefront, the same infrastructure can support several list types and brand-specific patterns.

Wishlist Stack includes a CSV import workflow for merchants moving from another wishlist platform or consolidating existing saved-product data.
