Wishlist Stack

Wishlist Stack delivers wishlist infrastructure for brands that need more than a basic widget. If you've struggled with wishlist apps that can't handle custom variant logic, specific metafields, headless architecture, or pixel-perfect design requirements, this is the solution you've been looking for. Built with an API-first architecture, Wishlist Stack provides a clean JSON API and TypeScript SDKs so you can build your own storefront UI while the backend stores wishlist data and keeps it hydrated with current product information from Shopify. No product cache to maintain—the app pulls fresh data directly from the Storefront API. Features include lists, groups, items, ordering, and sharing endpoints. Two SDKs are available: Universal for any JavaScript runtime and Hydrogen with React Router and hooks. Configure which product and variant metafields appear in the API response. Security is built-in with merchant key and customer token authentication for write operations. Perfect for brands running headless Shopify stores who want complete control over their wishlist experience.
