Check any Shopify store's PageSpeed and Core Web Vitals, find the apps and scripts slowing it down, compare Shopify plan fees, and get a headless estimate.
Scored across 4 tools
Each tool has a distinct purpose, and the potentially confusable pair (detect_shopify_store vs check_shopify_store_speed) is explicitly separated in the descriptions ('runs no speed test'). submit_feedback is clearly a meta tool unrelated to the analytics tools. Minor residual risk that an agent reaches for detect when it actually wants performance data, but boundaries are well stated.
All four names follow a strict snake_case verb_noun pattern (calculate_, check_, detect_, submit_) with the domain object clearly named. No mixed conventions or ambiguous verbs.
Four tools is lean but each has a clear job: fee comparison, speed analysis, platform detection, and feedback. It is on the thin side for a product surface, but nothing feels redundant or padded.
The core workflow (identify a store, measure its speed, weigh migration/plan costs, report issues) is covered end to end, with rich parameterization on the fee calculator. Gaps are minor: no cross-store comparison, no saved/historical result retrieval beyond the 24h cache, and no theme-detail or app-inventory-only view.
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 The variable Plus platform fee is unpublished, so pass plusQuoteMonthly if you have a quote.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.
Inputs: monthlyGmv (required), brands, market, billing, +14 more.
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.
Inputs: url (required), strategy.
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.
Inputs: url (required).
