Shopify Storefront Monitor

Drop-in monitor for any public Shopify store via the universal /products.json endpoint that every Shopify store exposes (unless explicitly disabled). Maps to "Shopify competitor monitoring", "DTC inventory drop alerts", "sale-tag tracking" briefs.

Built 2026-05-03 as Demo #10. ~30% of online stores run on Shopify — this same scraper works on tens of thousands of competitor stores by changing one URL.
