Remove base slug of Custom Post Types and change the permalink structure of Custom Post Types.

Custom Permalinks Manager for WooCommerce allows you to change WooCommerce permalinks and remove product and category slugs from URLs.

Set Custom Permalink Editor on a per-post, per-tag per-page, and per-category basis.

Remove Category URL strips the /category/ base from your category URLs, turning something like /category/my-category/ into simply /my-category/.
