Frequently asked questions
What theme is Shopify theme store ID 578?
Theme store ID 578 is Simple. That is the theme Shopify listed under this ID, and it stays true for any store carrying the number, whatever the theme has been renamed to since. We read it from live storefronts running the ID rather than from a published list, because Shopify does not publish one.
What is the latest version of Simple?
The newest version of Simple we detect on a live store is 12.6.1. Most stores on ID 578 are still on 12.2.1, so being behind the newest release is normal here rather than a sign something is wrong.
My store's code shows ID 578 but a different theme name. Which one is right?
The ID. The name in Shopify.theme is whatever the store owner or their agency typed, and renaming a client theme is routine, so a store on ID 578 can call it anything at all. The number was set by Shopify at install and cannot be edited, so a store reporting 578 is running Simple regardless of the label next to it.
How do you know ID 578 is Simple?
By agreement across the storefronts running it, not by one store's word. We group every scan that reports ID 578 and take the name most of them give, and the ID is only published here once enough separate stores agree. A few renamed copies get outvoted instead of counted, and readings where our detector could not name the theme are dropped before the vote rather than treated as a name.
Does theme store ID 578 change if I customize or rename Simple?
No. Editing the Liquid, restyling it beyond recognition, or renaming it in your admin leaves ID 578 exactly where it was. Shopify stamps the ID in when the theme is installed and never rewrites it, which is why it still identifies Simple years later, and why it keeps working after Shopify retires a theme from the Theme Store.
How do I check whether a store is running Simple?
Open the storefront's page source and search for Shopify.theme. If the theme_store_id field there reads 578, the store is on Simple, whatever the name beside it says. Our scanner reads the same field, along with the theme version and the apps the store runs, if you would rather not read the source yourself.
How this data works
Theme store IDs, theme names and versions are read from the storefront itself on every scan our detector runs, so the mapping is evidence from live stores rather than a curated list. Each ID is named by majority agreement across the stores reporting it, and an ID with too little agreement behind it is left unpublished instead of guessed at.
Independent by design: rankings are determined solely by live detection data. Affiliate relationships never affect what ranks or how stores are counted. Read the full methodology →
