What is WooCommerce?

WooCommerce is an open-source e-commerce plugin for WordPress that transforms WordPress sites into fully functional online stores. Launched in 2011 and acquired by Automattic in 2015, WooCommerce powers approximately 28% of all online stores globally, making it the most widely used e-commerce platform.

WooCommerce is designed for businesses that want to combine content marketing with e-commerce using WordPress. It’s particularly popular with small to medium businesses, content-first retailers, and anyone familiar with the WordPress ecosystem.

The core plugin is free and open-source, with revenue generated through extensions, themes, and WooCommerce.com services.
