SKU Generator
What is SKU Generator?
Free in-browser SKU generator for ecommerce merchants. Enter a prefix plus attribute axes (size, color, material, etc.) and get a live variant matrix with duplicate flags.

SKU Generator FAQ
Is SKU Generator free to use?
Yes. The website does not charge for access and requires no account. It does not load advertising scripts. Request logs for page loads are separate from the generated codes.
Does SKU Generator store my product data on a server?
No. Generation runs entirely in your web browser. The site does not save a product catalog or transmit your codes to external servers.
What is the maximum number of SKUs I can generate?
The tool warns at five hundred codes and enforces a hard limit of two thousand. It supports up to twelve attribute axes with twenty values per axis. The prefix allows sixty four characters.
Can I use the generated codes for commercial products?
Yes. The strings you create belong to you for use in your catalog. You remain responsible for ensuring uniqueness, avoiding trademark conflicts, and following each sales channel rules.
Is this software for tracking inventory levels or warehouse orders?
No. This page only builds variant SKU strings from a prefix and attributes. Stock levels, purchase orders, and warehouse workflows must be managed in your store or ERP system.
