f(x) Builder


f(x) Builder 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).


You can contribute to development at GitHub https://github.com/turtlepod/fx-builder

Perfect for me!

I’ve used several Page Builders, but none integrates as perfectly as the f (x) Builder plugin.
Clean design, very lightweight and easy to use make this plugin essential for any WordPress site.
Please continue with this beautiful development, I sincerely do not know if it needs any improvement, it is perfect for me.
Many thanks to the developer!

Like it works itself!

I mean it works without me thinking how to use it), which is unbelievable for a builder. Simple and efficient. I tried it yesterday when it was alpha, today is beta, I liked UI improvement. Great potential!

EXACTLY What I was craving for!!!

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.
