How the tools handle your numbers.
-
They work as you type
Each tool does its work in the page you have open, so results update the moment you change a number or a color. There is no account to make and no email to hand over.
-
They show their sources
Every tool lists where its rates and rules come from and the date we last checked them against Shopify, GS1 or the standard behind them. When something has not been checked, the page says so instead of guessing.
-
They give you a link back
Your inputs live in the page address, so you can bookmark a result, a palette or a barcode, or send it to a business partner, and they see the same thing.
Setting up swatches on your theme?
The theme guides walk through Shopify's own swatches, apps and code, one theme at a time.
