Shopify Dev Toolkit by Zenvix Web

About

Shopify Dev Toolkit is a fast, all-in-one diagnostic extension built for Shopify developers, agencies, and store owners who want real answers, not another dashboard full of unlabeled numbers.

Click the icon on any Shopify store and instantly see:

THEME
Theme name, ID, internal name, version, and publish status — plus one-click links to the code editor, customizer, admin, and theme preview.

APP BLOAT
See every app running on the store, flagged by real impact — not guesswork. Know which apps are actually slowing things down before you start optimizing.

CORE WEB VITALS
LCP, INP, and CLS shown against Google's real thresholds — see exactly where a store lands, not just a raw number.

SEO & STRUCTURED DATA
Full JSON-LD schema viewer with both a developer (syntax-highlighted JSON) and simple (plain-English) view. Catch missing Product schema, broken headings, and heading-level skips before Google does.

META & SOCIAL
Open Graph and Twitter card tags at a glance, with clear flags for what's missing and why it matters.

IMAGES, LINKS & ASSETS
Full audit tables — oversized images, missing alt text, broken or insecure links, render-blocking scripts — with per-item copy buttons and CSV/JSON export.

EXPOSED DATA VIEWER
See exactly what JSON data a theme already exposes client-side — cart, product, and JSON-LD data — without guessing at Liquid internals.

ONE-CLICK DEBUG REPORT
Generate a complete, shareable debug report in one click — perfect for handing off to a developer or documenting an issue.

Built by Zenvix Web, a Shopify development studio. If a scan turns up real issues, you can request a free, no-obligation audit directly from the popup.

Privacy: this extension only runs when you click it (no background access), never collects personal browsing data, and the only external request it makes is an optional Core Web Vitals check via Google's PageSpeed Insights API. Full privacy policy: zenvixweb.com/privacy/shopify-dev-toolkit
