Shopify Dev Helper

Developer tool for Shopify theme development — AJAX API, theme preview utilities, and more

Shopify Dev Helper A Chrome side panel extension for Shopify theme developers. Think Postman, but built specifically for the Shopify AJAX API — living right next to your browser tab. No console. No custom scripts. No copy-pasting URLs. Just open the panel, navigate to any Shopify store, and start making requests. AJAX API Make live requests to the Shopify AJAX endpoints on any store you have open: Get Cart — fetch the full cart object as JSON Add to Cart — add any variant by ID with quantity, properties, and selling plan Update Cart — change quantities, set a cart note, or update cart attributes Change Item — modify a specific line item by variant ID or line number Clear Cart — remove all items, clear attributes, or wipe the cart note individually Discount Codes — apply or remove discount codes via the cart update endpoint Get Product — fetch complete product data by handle, with one-click detection from the current page Product Recommendations — retrieve related or complementary recommendations for any product Predictive Search — query the search suggest endpoint with configurable resource types, fields, and result limits All responses are shown in a collapsible, searchable JSON viewer so you can navigate large objects quickly. Theme & Admin Theme utilities and admin navigation in one place: Open Customizer — jump straight to the Theme Editor for the active theme Code Editor — open the theme code editor for the active theme Open Page in Customizer — open the Theme Editor with the current storefront page already loaded as the preview, so you edit exactly what you're looking at Open in Admin — detects the current page and opens the matching admin record in one click. Handles products, collections, pages, articles, and blogs automatically. On the homepage, it redirects to the Customizer Preview Banner — show or hide the Shopify theme preview bar without touching the URL manually Copy Preview URL — copy the current page URL with ?preview_theme_id= filled in automatically from window.Shopify.theme.id Page Context Inspector — read ShopifyAnalytics.meta and Shopify globals to see page type, product, theme, currency, and locale data at a glance Quick Navigation — one-click links to Dashboard, Products, Collections, Orders, Customers, Themes, Pages, Blog Posts, Files, and Metafields & Metaobjects Why developers use it Requests run inside the active tab, so they behave exactly like real storefront requests — no CORS errors, no authentication workarounds. Form values and responses are saved for the duration of your session, so you can switch tabs and come back without losing your work. It works on any Shopify online store, including development, staging, and password-protected preview themes. Permissions The extension requests only the permissions it needs: Active tab and scripting — to inject fetch requests into the current Shopify tab (required to bypass CORS) Side panel — to display the extension UI Storage — to save form state locally within your browser session Tabs — to detect store changes and open admin or documentation links No data is ever collected, transmitted, or stored beyond your local browser session.
