Shopify Speed Check

Test a Shopify store's speed with Google PageSpeed Insights (mobile and desktop) and real-user Core Web Vitals, list the apps and scripts slowing it down, and estimate what a headless build could change, with its assumptions. Takes 10 seconds to 2.5 minutes; results are cached for 24 hours.

Detect whether a site is a Shopify theme store or a headless Shopify storefront, and which theme it uses. Fetches only the public page; runs no speed test.

Compare the monthly and annual cost of Shopify Basic, Grow, Advanced and Plus for a sales volume and payment mix, with break-even sales between plans and requirements only Plus covers. Uses Shopify's published prices and rates for the US, UK, Australia, Norway or New Zealand (market); Norway's Plus and New Zealand's subscriptions are billed in EUR or USD and converted at a dated ECB reference rate, reported in exchangeRate; pass exchangeRate to use your own. The variable Plus platform fee is unpublished, so pass plusQuoteMonthly if you have a quote. Only monthlyGmv is required; the rest defaults to one US brand fully on Shopify Payments with yearly billing.
