<a href="http://genbumedia.com/plugins/fx-builder/" rel="nofollow ugc">f(x) Builder</a> is a new page builder plugin that provides visual columns in the post editor without using shortcodes. From the setting page, you can enable it for posts, pages, and custom post types. There is no vendor lock-in. If you decide you no longer wish to use the plugin, you can disable it without losing your content (though you would loose the column formatting).

f(x) Builder

No bells and whistles, just a plain and simple page builder, with a FULL editor at our disposal. Perfect for those who create their own themes or shortcodes or use some quality shortcodes plugins. 

What's really amazing is that it add 0 (ZERO) strain on the server - the page loads are exactly the same with this page builder active or not. If you are using a shared hosting, and especially if you are using a "heavy" plugin like Woocommerce, and if you want to have a page builder without effecting the speed of the site, then besides a good theme and agood cache plugin, this is the page builder to use.

I cannot specify how excited I'm with this, I hope they don't add too many things to it. There are a million other page builders that have plenty of features, at the expense of speed and memory (RAM). We needed at least one that is extremely lightweight, and this is it. Besides, there is no way any builder plugin can compete with Visual composer, so dominating a different niche is very clever. 

If anything that needs to be added, the ability to have full width content when the theme is fixed width, ala Visual Composer, or SiteOrigin. The Divi builder plugin and the Beaver builder plugin fail miserably with this. 

EXACTLY What I was craving for!!!

Exactly what I was looking for. Thanks a lot. Works great.

This is awesome!

A simple page builder plugin. The one you can actually use.
