You shipped the new theme. You checked it on your laptop. It looks great. Then a customer emails you: "I can't add to cart on my phone." That's how Shopify store owners lose revenue — not from one catastrophic failure, but from a quiet stream of broken experiences on devices you didn't test.
BugSense scans your Shopify storefront across mobile, tablet, and desktop — the same way a real customer would browse — and flags the issues that are actually costing you conversions.
Broken product images after theme updates
After a theme edit, image CDN paths or lazy-load configurations can break silently. Visitors see empty product cards, and without a screenshot of what your customers actually see, you may never know.
Mobile checkout tap targets too small
Shopify themes often render "Add to cart" and checkout buttons at desktop sizes. On a 375px iPhone screen, buttons overlap adjacent elements or require pixel-perfect taps that frustrated shoppers give up on.
Collection filter UI collapsing on mobile
Faceted filters built with JavaScript dropdowns frequently break on narrower screens. The filter drawer renders off-screen or the close button is unreachable — leaving customers stuck with an unfiltered list.
Missing image alt text hurting search rankings
Bulk-uploaded product catalogs often land with empty alt attributes. This limits accessibility, reduces Google image search visibility, and flags your pages in Core Web Vitals audits.
Abandoned cart email triggers not firing
Theme scripts that track add-to-cart events for email flows can break after app updates or section customizations. Your Klaviyo or Omnisend sequences go quiet without any obvious error.
Shopify makes it easy to launch — it also makes it easy to accidentally break things when you install a new app, publish a theme update, or customize a section. Each of those changes can introduce regressions across device types without triggering any visible errors in your admin.
Mobile accounts for more than 70% of e-commerce traffic on most Shopify stores. Yet desktop is where most merchants do their testing. This gap is where revenue leaks: a misaligned Add to Cart button, a gallery that only scrolls horizontally on iOS, a checkout form whose inputs require double-tapping to focus.
BugSense launches a headless browser session against your storefront and captures full-page screenshots on a 375px mobile screen, a 768px tablet, and a 1440px desktop. The AI then compares what's rendered against what should be there — flagging broken images, layout overlaps, inaccessible buttons, and slow-loading assets that inflate your bounce rate.
For Shopify merchants specifically, BugSense also watches for theme publishes via Shopify webhooks. When you or a developer publishes a theme change, BugSense automatically triggers a re-scan within minutes. If the change introduced a new high-severity issue — a broken product page layout, a checkout form that no longer renders — you'll know before your customers do.
Fixing a broken mobile checkout doesn't require a developer. BugSense gives you the exact CSS change or copy correction needed. Paste it into your theme editor, save, and re-scan to confirm the fix. Most issues are resolved in under 15 minutes.

Does BugSense work with any Shopify theme?
Yes. BugSense scans the live storefront URL, not the theme files directly. It works with Dawn, any paid theme, or a fully custom theme. For Shopify merchants using the native integration, BugSense can also read your published theme files for deeper analysis.
Will scanning slow down my store or affect my customers?
No. BugSense runs scans from external servers against your live URL — exactly like a search engine crawler would. It never modifies your store, injects scripts, or affects your storefront performance for real visitors.
How is this different from Shopify's built-in analytics?
Shopify analytics shows you traffic and conversion numbers. BugSense shows you why conversions are dropping — broken images, layout bugs, slow sections, inaccessible elements. Numbers tell you something is wrong; BugSense shows you exactly what.
How often should I scan my Shopify store?
Any time you publish a theme change, install or update an app, or change your product catalog structure. On BugSense's Pro and Agency plans, Theme Change Shield triggers a scan automatically after every theme publish.
