Domain
Ecommerce app marketplaces
Marketplaces that extend online stores, checkout, and merchant operations. Ideal if you are building apps for merchants who monetize a storefront.
10 marketplaces in this directory match this tag.
Ecommerce app marketplaces reach merchants actively looking to add functionality to their stores — subscriptions, reviews, upsells, shipping, tax, and marketing. Because the buyer is a business owner losing revenue to every gap in their stack, willingness to pay is high and distribution is built into the host platform.
The dominant surface is the embedded app rendered inside the merchant admin, with OAuth 2.0 auth and webhooks for order and product events. Shopify offers the largest paying audience and the strictest review bar; WooCommerce, PrestaShop, and Magento trade central distribution for open, self-hostable extensibility.
