SiteOrigin Page Builder
Build responsive page layouts using the widgets you know and love using this simple drag and drop page builder.
However, by far the most interesting characteristic of it is that it’s completely free. There’s not one locked feature and nothing behind a freemium gate. This will allow you to work with the WordPress widgets available on your WordPress website so using this will be a breeze.
The live editing feature will let you edit and see the content on the widgets in real-time which is a great thing. You can track the changes you made with the history browser and you can easily roll back a change you don’t need. You add new blocks by clicking either the “Add Row” or “Add Widget” button. There’s also some drag-and-drop functionality for realigning the blocks.
