ListingGuard is a Windows desktop app for growing Etsy shops. It connects through Etsy authorization with no API keys, then provides a read-only view of listing changes, favorites and favorite growth, duplicate, pricing, sale, and consistency issues, plus a Priority Watchlist and Windows notifications.
ListingGuard was built to help Etsy sellers monitor larger catalogs without repeatedly checking every listing by hand. The goal is to surface meaningful changes and possible listing problems in one focused, read-only desktop workspace.
