SKU Generator Plus is a Shopify app that builds SKUs from blocks: vendor, product type, tag, collection, variant options, static text and counter. A bulk run fills empty or replaces existing SKUs and can copy SKUs to the barcode field (off by default; replaces barcodes), but assigns no GTIN or EAN numbers. Auto-rules give new products a SKU, and barcode labels print as PDF from a limited SKU list.

• SKU format blocks: vendor, type, title, tag, options, date, static text, counter
• Preview current and new SKUs for a sample of variants before anything is written
• Auto-rules give new products a SKU by vendor, product type or tag
• Print PDF barcode labels from a limited SKU list, Code 128 or QR
• Run history lists old and new SKUs per variant; undo runs

Breadcrumbs Pro is a Shopify app that adds a breadcrumb trail to your storefront with a theme app block. The trail ships with schema BreadcrumbList JSON-LD and microdata, which search engines can show as the path of a page. Trails follow your collections and can show the collection a shopper came from. A Design page with a live preview sets style, labels and page types. Custom paths replace the trail of single pages, and data files map your catalog paths for SEO tools and AI search.

• Theme app block shows a breadcrumb trail on products, collections and articles
• Writes schema BreadcrumbList JSON-LD and microdata for search engines
• Design page with style presets and a live desktop and mobile preview
• Custom paths for single products, collections, pages or articles
• Plain-text path tag, breadcrumbs.json and llms.txt for AI search tools
