Lisa Norman

Overhauled Builder UI

Modern. Sleek. Fast.

Fewer Clicks

Reach commonly used buttons & controls without extra clicks. Super fast, super efficient.

Easier Changes

Double click to edit element names in the Properties Pane or the Structure Pane.

Powerful Enhancements

See inherited values & whether a property is styled via Class or ID at a glance. Search for selectors. And much more.
"Finally, a page builder that actually gives you full control. I definitely don't miss trying to hack around Elementor. I love Oxygen."
Jonathan Killian


We've improved several Oxygen features

Even Better Performance

We've made even more changes to the back-end of Oxygen to make it load and work faster for you.

Image Changes

Use dynamic data for Image Library images, and their alt text syncs with the library. Easily control object fit, object position, and aspect ratio.

Keyboard Shortcuts

Including undo, redo, delete, duplicate, and copy & paste.

PHP 8.x Compatible

Oxygen 4.0 is fully PHP 8.x compatible.
"Oxygen is the best tool I've ever used to build websites."

  1. Switching to OxygenBuilder is the best thing I've done for my website building business -- after using Divi, Beaver, Headway and others. I have excellent design flexibility, a great development experience, and the fastest loading site pages. And, a lifetime license. It's a no-brainer.

  2. I've been using Oxygen Builder for over a year now. Hands down the best lifetime software purchase I've ever made in my life. Super easy to use, even for a non-coder like myself. Can't wait to load up v4!

  3. Thank you so much. v4.0 is better, easier, and faster. Infect, I love the new look. Everything is better

  4. Oxygen is already a great tool to use, and I'm happy using it as it is... but, you guys should really look into integrating crocoblocks - jetengine and all their suits of plugins into oxygen cus that will definitely become a game changer. I'm patiently waiting for this change since 2020 and up until now nothing yet. Please work with the crocoblocks teams to make their product sync with oxygen builder then elementor will be eleminated completed cus as it is I still use elementor and it's heavy.
