WPBakery Page Builder is a popular drag-and-drop page builder plugin for WordPress that allows users to create custom layouts and designs without any coding knowledge. It offers a user-friendly interface with both front-end and back-end editors, making it easy to design pages in real-time or through a traditional editor. WPBakery comes with a variety of pre-built content elements like text blocks, buttons, sliders, and more, along with numerous templates and design options. It also integrates seamlessly with other WordPress themes and plugins, including WooCommerce for building eCommerce sites. WPBakery is available in a premium version, and while some third-party providers offer it under the GPL (General Public License), these versions typically do not include official support or updates from the developers.
