About

Cart Forge lets you inspect and modify Shopify cart data without using the browser console or writing custom scripts.

### What it does

Inspect cart data:
- View cart contents in a readable, collapsible format
- See cart attributes, line item properties, cart notes, and all cart data
- Dark mode interface with syntax highlighting

Manage cart data:
- Modify cart notes
- Modify cart attributes & line-item properties (add, edit, or remove key-value pairs)
- Modify line-item quantities
- Search products and add variants to the cart (selling plans supported)

Developer workflow:
- Debug checkout flows by inspecting cart state
- Verify cart-dependent integrations

How it works:
Click the extension icon while on any Shopify store. The popup shows your current cart data. Make edits directly in the interface. The changes apply to the store immediately using Shopify's cart AJAX API.
