About the Still Sleepy Storefront Guard
Still Sleepy Storefront Guard tests your Shopify theme changes in a real browser before you publish them live. This app catches regressions and broken shopping behavior by checking key pages including home, collection, product, search, and cart pages on both desktop and mobile viewports.
The app verifies critical storefront flows like Add to Cart functionality and Shopify cart state, while detecting JavaScript errors, failed resources, and accessibility issues. It captures screenshot evidence and groups findings so you can quickly identify problems.
Compare your unpublished theme against the live storefront across matching routes to spot new regressions, fixed issues, and visual changes. This helps prevent publishing theme updates that could break important shopping features and impact your customers' experience.
