What stops working on Shopify on 1 March 2027
On 1 March 2027 Shopify stops loading script tags on online stores, so any app feature that still loads through a script tag disappears from the storefront without an error.
What a script tag is
A script tag is an older way for an app to add JavaScript to your storefront. The app registers the script with Shopify, and Shopify adds it to every page of your online store, whatever theme you use.
Shopify's replacement is the app embed: a block that ships inside the app and that you switch on in the theme editor. Scripts that only collect analytics can move to a web pixel instead, which needs nothing from you.
The two dates
- 1 October 2026: apps can no longer create or update script tags. Script tags that already exist keep running.
- 1 March 2027: Shopify stops adding script tags to storefronts. Whatever they load stops loading.
What disappears
Anything an app still loads through a script tag. In practice that is usually one of these:
- Product reviews and star ratings
- Live chat and help widgets
- Pop-ups and email sign-up forms
- Tracking and ads conversion pixels
- Upsell, bundle and cart offers
- Scripts you or a developer added yourselves
Why many stores won't notice
There is no error message and no notice in the admin. The page still loads; the feature is simply not there. A missing reviews block or a tracking pixel that stops firing can go unseen for weeks, while sales and ad reports quietly get worse.
What to do before the deadline
- Find out which scripts on your store still load as script tags.
- For each installed app, update it or switch on its app embed if the developer already offers one.
- Remove code left behind by apps you no longer use.
- Move scripts you added yourself to a supported method.
