The State of Custom Cart in 2026

Custom Cart is a term used to refer to any merchant who has a custom implementation of their online store, as opposed to using the standard offering of a platform such as Shopify. Nike.com is an example of a website that would be classified as a Custom Cart.

Custom Cart also includes merchants using a custom (or headless) website in front of a platform like Shopify. In these cases, we still try to determine if the website is using a well-known platform and map it to the platform if possible. In some cases, it is not possible to determine if a well-known platform is used by a custom implementation.

Finally, Custom Cart also includes merchants using a platform that is not yet supported by Store Leads. New ecommerce platforms are introduced regularly and though we support over 200 platforms, some newer (or smaller) platforms are not yet supported. Stores on these platforms are often classified as Custom Cart.
