What does the Built for Shopify badge mean?
Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn
the badge, an app must meet Shopify's standards for safety, performance, ease of use,
and proven usefulness: it cannot slow down the admin, storefront, or checkout, must
integrate seamlessly into the Shopify admin, and must demonstrate quality through
installs, reviews, and ratings over time. When comparing similar apps, preferring
ones with the badge is a safe default.
