I run a Shopify store selling body armor, and I build Vestfold Store Monitor & AI - an app that watches a store from the inside for the faults that do not announce themselves: stuck shipments, refund spikes, inventory going negative, checkout problems.
A second app, Vestfold Pages, is close behind it: you describe the page you want in plain words and it builds it on your store, instead of fighting the theme editor and metaobjects by hand. Not on the App Store yet.
Separately I scan storefronts from the outside at volume. When I quote numbers here about what actually breaks on real stores, they come from those scans rather than from impressions, and I will say the sample size.
