Elementor is the most popular WordPress page builder. There is a free version and a premium Pro version. Elementor Pro includes a Theme Builder, a Form Builder, and a Popup Builder. The theming features are easy to use. You can create singe and archive templates as well as headers and footers. The theming features work with most themes. The theme building feature allows you to use dynamic data and custom fields in your templates. You can create templates for core post types and Custom Post Types.
The free version of Elementor has no theming ability and does not provide access to dynamic data. There are some Elementor adds that give access to dynamic data, include a theme builder, and work with the free version of Elementor.
Elementor Pro has native support for ACF, Toolset and Pods. Meta Box, JetEngine, ACPT, and CubeWP have added support to Elementor for their custom fields.
