Store builders

The store builder is the platform everything else plugs into: the storefront, the product pages, the cart and checkout, payments and the order admin. Picking one is the biggest technical decision a new online store makes, because moving later means rebuilding pages, redirecting old URLs and reconnecting every app.

All of the builders listed here now ship AI features inside the admin. The common ones draft product descriptions, suggest page layouts, write email or blog copy and answer questions about your own sales data. These save time on routine work. They don't change the basics of a good store, which are clear photos, accurate product details, fast pages and a checkout that works on a phone.

The real differences sit elsewhere. Some platforms are built mainly for selling and have the deepest app stores, so most of the other tools on this site connect to them first. Others started as website builders and are strongest on design and content, with a store added on. A few aim at larger catalogs, B2B pricing or several storefronts from one back office.

Before you choose, list what the store has to do in its first year: how many products and variants, which payment methods, whether you sell in other countries or currencies, whether you need wholesale prices, and which marketing tools you already use. Then check each platform's transaction fees, its plan limits and whether the apps you need exist for it. A free trial with your real products and a test order tells you more than a feature list.
