I have been using Beaver Builder to build websites right from the beginning when I started using WordPress.
There are many choices that are out there, including DIVI, Elementor, and Visual Composer (now known as WPBakery Page Builder for WordPress), but right from the start I felt most comfortable with what Beaver Builder offered. It is a clean and easy to use environment, allows easy customization through the use of CSS. It has been extremely stable and the makers of Beaver Builder are meticulous in testing the software before releasing it on the public. That gives peace of mind that as the software progresses, it all still works!
The online community on Facebook and the helpful people who support the community with videos, podcasts, and answers to the smallest questions help to make Beaver Builder my page builder of choice!
