Bricks Builder is a WordPress page builder with a focus on speed and customization. The builder is newer, only on version 1.0. Not unlike other page builders, you can visually design your WordPress site. The difference with the builder is the unique ability to add custom code and build your own elements in PHP, CSS, and HTML.
Pricing currently is $79 for a lifetime account on one website, for unlimited websites on the lifetime account it is $199. Bricks Builder will likely move to a monthly paid model, but in later more stable versions.
