WooCommerce
WooCommerce is an open-source e-commerce plugin for WordPress that transforms a WordPress site into a fully functional online store. It provides features for product management, payments, shipping, taxes, and order handling, leveraging WordPress's flexibility and extensive plugin ecosystem. It is widely used for building customizable online shops, from small businesses to large enterprises.
Developers should learn WooCommerce when building e-commerce solutions on WordPress, as it is the most popular e-commerce platform for WordPress with over 30% market share. It is ideal for projects requiring deep customization, integration with WordPress themes and plugins, or when clients prefer a self-hosted, scalable solution over SaaS platforms like Shopify. Use cases include creating bespoke online stores, subscription services, or multi-vendor marketplaces.
