CatalogDiff
Compare supplier CSVs before updating your store
Compare supplier CSV catalogs, detect price and stock changes, identify new or removed products, and export safer catalog updates.
Hey Product Hunt 👋
I built CatalogDiff after noticing how messy recurring supplier CSV updates can be.
The workflow is simple: upload the previous supplier CSV and the new one, choose the SKU/EAN/ID column, and CatalogDiff shows what actually changed — prices, stock, new products, removed products, and duplicate IDs.
One thing I cared about from the start was privacy, so the CSV files are processed locally in the browser rather than uploaded to our servers.
There’s a free version for smaller catalogs and a €9.99 one-time Pro option for larger files and exports.
I’d really appreciate feedback from anyone who works with supplier catalogs, Shopify, WooCommerce, or product data regularly.
