- See your live store and the new theme side by side, with changes marked.
- Checks run automatically whenever a theme is edited or published.
- A real browser confirms customers can still add to cart and reach checkout.
- Every change traced back to the theme section it came from.
- Read-only. Never changes your theme, products, prices or checkout.
See exactly what a theme update changed on your storefront, before your customers do.
Theme updates break stores quietly. A header shifts, a button disappears, an image stops loading, and nothing tells you until sales drop. StoreGuard checks your storefront every time a theme is edited or published. It shows your live store next to the draft theme, page by page, with changed areas marked and traced back to the section they came from. A real browser also opens a product, picks a variant, adds to cart and confirms checkout is reachable. Read-only: it never changes your store.
