This plugin also provides multi vendor options for your WooCommerce store and an original product from WooCommerce itself. Much feature has been added in the last update. However, it still has a long way to go for competing with the other three.
WooCommerce Product Vendors works on the backend of your site, just like WooCommerce. It does provide multi vendor capabilities to your store, but only admin can create or update products. So, this plugin makes it hard for the Admin. However, you can install Frontend addon for this plugin with additional price and get frontend capabilities. Dokan or WC Vendors has more options than this plugin.
