Cart Tools for Shopify is a free Chrome extension designed specifically for developers working with Shopify storefronts. It offers essential debugging and inspection functionalities that simplify the process of managing the shopping cart using Shopify's AJAX Cart API. Key features include the ability to view a cart summary at a glance, log formatted cart data directly to the browser console, and copy complete cart JSON to the clipboard. Additionally, users can empty the cart with a single click and monitor real-time cart item counts through a badge on the extension icon.

This tool is particularly beneficial for Shopify theme developers, frontend developers, and QA engineers, providing them with quick access to cart inspection tools necessary for testing and verification. The extension is compatible with classic Shopify themes and any storefront that utilizes the AJAX Cart API, though it does not support headless implementations without standard cart endpoints. Notably, it prioritizes user privacy, as it does not collect or share any data, ensuring that all operations are carried out locally.
