Not just a page builder

Everything a real project needs.

Turn on the pieces you want and leave the rest. Every part is optional except the framework itself.

Theme settings & options

Describe a settings panel as a plain PHP array. The framework renders it, validates it and saves it, with more than seventy option types to build from.

Custom fields & post types

Field groups, custom post types and taxonomies, defined in the admin. Read the values in a template with a single call, or bind them to a builder element.

Page builder

Sections, rows and nested columns with a large element library, plus a live editor that works on the real front end. Optional, like everything else.

Theme builder

Global headers, bodies and footers assigned by conditional rules, so the chrome is built in the same place, and the same way, as the content.

theme-settings.php
$options = array(
    'brand_color' => array(
        'type'  => 'color-picker',
        'label' => 'Brand color',
    ),
    'headings' => array(
        'type'  => 'typography-v2',
        'label' => 'Heading font',
    ),
    'content_width' => array(
        'type'  => 'unit-input',
        'label' => 'Content width',
    ),
);

The options framework

A settings panel from a plain PHP array.

Theme Settings, page-builder element options and post meta boxes are all built from the same option types. Describe the controls you want and the framework renders, validates and saves them, then hands the values back as design tokens the whole site reads.

Custom fields & content types

Structure content without writing a plugin.

Build field groups and register custom post types and taxonomies right in the WordPress admin. Read the values in a template with one call, or drop them into a page-builder element and let an editor fill them in.

The page builder

Visual layouts, when you want them.

A true visual builder with nested columns, sections and full-page templates. When you want to fine-tune, the Live Editor lets you click any element on the real front end and change it in place.

  • 60 ready elements

    Galleries, sliders, tabs, accordions, counters, posts, testimonials, maps and more, each with multiple designs.

  • Per-device control

    Override spacing and layout for phone, tablet and desktop without touching CSS.

  • Header & footer builder

    Design your site chrome visually and assign it per page or site-wide.

Site Converter

Made your site with AI? Move it to WordPress, cleanly.

Site Converter rebuilds an AI-generated or hand-built site as native WordPress. Your media, styles, menus and pages come across as editable page-builder layouts, with a real theme for the header and footer. Not a frozen copy.

  • Media, styles and menus imported

    Images land in the Media Library; palette, fonts and navigation rebuild themselves.

  • Pages become editable layouts

    Each page is recreated in the builder, ready to change, not a locked block of HTML.

  • A real theme, no lock-in

    It even generates a theme from your header and footer. The result is plain, GPL WordPress.

The theme

A Bootstrap 5 theme that speaks fluent framework.

The companion parent theme is clean, responsive and built for the framework, with a sample child theme to fork. Or keep your own theme: the preset system works on any WordPress theme.

Animation Engine

Motion that used to need a developer.

A free, bundled extension — GSAP-powered scroll motion, parallax, cursor and hover effects, animated backgrounds, text effects and page transitions. Activate it in one click, then tune every effect per element.

Scroll Motion

Reveal, stagger and scrub any element to the scroll — powered by GSAP + ScrollTrigger.

Parallax & Pin

Depth on scroll — layers that drift at their own pace, and sections that pin as the page moves past.

Text Effects

Split, type-on, scramble and gradient-animate headings — word by word or character by character.

Cursor & Hover

Custom cursors and rich hover interactions — magnetic buttons, tilt, spotlight and marquee.

Animated Backgrounds

Gradient meshes, particles and WebGL scenes as living section backgrounds, plus 3D model and SVG-draw elements.

Page Transitions

Smooth, app-like transitions between pages — no jarring white flash on every click.

Get the framework. Free, forever.

Install the plugin, switch on the pieces you need, and build. GPL licensed, updated from GitHub, with the whole manual a click away.
