Swatch King works with almost every Shopify and third-party theme, and in most cases it works as soon as you enable the app embed — no code, and no setup beyond assigning your styles.
A small number of themes are built in a way that needs a one-off adjustment on our side. This is not a paid service and not something you need to configure: our team adds support for your theme and it starts working.
How to tell which you have
Enable the app embed in Theme settings → App embeds → Swatch King, assign a style to one of your options, and open a product page. If your swatches appear and selecting one updates the price and image, you are set.
If they do not appear, or they appear but nothing updates when you click, send us a message in the chat with:
your store URL
a link to one product where you expect to see swatches
the name of your theme
That is everything we need to identify it. Most theme adjustments are turned around quickly.
Testing on an unpublished theme? Swatch King can run there too — enable the app embed on that theme specifically. Your live storefront is unaffected.
