The Breakdance page builder is a newer builder option, from the same company that created the Oxygen builder. It targets people who want an easy to use builder, fast workflow, with clean output. It is full featured, which cuts down on the need to third party addons. Breakdance has good support for custom fields and dynamic data. In addition to being a page builder, it has full theme builder functionality.
Breakdance is relatively new, yet is already full featured. People who find Bricks too complex and don’t like Gutenberg may be happy with Breakdance. It is powerful, flexible, and easy to use.
