WC External Variations is a free WordPress plugin designed to enhance WooCommerce by adding basic support for external products and their variations. This plugin allows users to define an external URL for each variation, which opens when the ‘Add to Cart’ button is clicked. It also includes features such as shortcode support for displaying product attributes and custom fields, as well as the ability to set an external SKU for tracking purposes. However, users should note that it has not been actively developed since March 2023 and may not function properly with other plugins that alter the Add to Cart button.

The plugin offers customizable settings accessible through WooCommerce settings, allowing users to choose how links open and modify the button text for external variations. With a known limitation on the number of variations (stopping at 30), users can bypass this with specific filters as outlined in WooCommerce's documentation. It is advisable to test this plugin in a standard WordPress/WooCommerce environment for optimal performance.
