Plugins that don’t require special add-ons

The data of some plugins can be broadcasted using either the basic Broadcast plugin, or using a generalized add-on instead of an add-on only for that exact plugin:

Gutenberg Reusable Blocks just requires the wp_block custom post type.

Visual Composer / WP Bakery stores its data in shortcodes. You’ll be interested in the Shortcode Attachments add-on.
