About

Every Shopify store publishes its whole catalogue at /products.json with Access-Control-Allow-Origin: *, which means a static page can audit any store with no backend at all. This is that. One HTML file on GitHub Pages, no server, no analytics, nothing leaves your browser. It flags published products where every variant is out of stock. Those pages stay indexed, keep taking ad clicks, and keep getting submitted to Google Shopping, where out-of-stock items are suppressed rather than sold.
