Which WooCommerce plugins support the Cart and Checkout Blocks?

The most-installed plugins that do not declare Checkout Blocks compatibility are WooCommerce PayPal Payments (800,000+ installs, not declared), WooCommerce Tax (formerly WooCommerce Shipping & Tax) (500,000+ installs, not declared), WooCommerce Legacy REST API (400,000+ installs, not declared), Cart Abandonment Recovery for WooCommerce – Recover Lost Sales with Automated Emails (300,000+ installs, not declared), PDF Invoices & Packing Slips for WooCommerce (300,000+ installs, not declared). Of the 508 most-installed WooCommerce plugins on WordPress.org, 114 (22%) declare Checkout Blocks compatibility in their code, 5 declare themselves incompatible and 389 (77%) do not declare it, as of 8 November 2026.

The Cart and Checkout Blocks replace the classic [woocommerce_cart] and [woocommerce_checkout] shortcodes and are the default for new stores since WooCommerce 8.3. Plugins that add fields, fees, payment methods or messages to the cart or checkout have to integrate with the blocks to appear there; a plugin declares that it does with FeaturesUtil::declare_compatibility('cart_checkout_blocks').

In WordPress, go to WooCommerce → Settings → Advanced → Features: WooCommerce lists the active plugins that are incompatible or uncertain. You can also paste your plugin list into our free compatibility checker, or look a plugin up in the table on this page (read from each plugin's code, re-checked whenever a new version is released).

We take the 508 most-installed plugins tagged "woocommerce" on WordPress.org that require WooCommerce, download the current version of each and read its code for FeaturesUtil::declare_compatibility() and the "WC tested up to" header. Declared means what the plugin's own code states; it is not a lab test. Premium plugins sold outside WordPress.org are not in this list.
