What it does
Many people like the WordPress Block Editor but find the default blocks limited when they want more design control. The usual fix is to stack several block addons or switch to a separate page builder. This plugin brings those page builder style options into Gutenberg itself, with a single library of essential and advanced blocks, plus a design library of ready-made layouts and UI kits you can adjust to match your brand.
You work inside the editor as normal, choosing blocks and styling them with responsive live editing for desktop, tablet and mobile. Custom breakpoints let you set your own responsive rules, and a global design system keeps colors and styles consistent across the site. Dynamic content connects blocks to custom fields, and conditional display shows or hides blocks by user role, device type or other conditions. It also works with Full Site Editing, so headers, templates and pages can all be designed in Gutenberg.
Best for
- Bloggers who want more layout control in Gutenberg
- Designers building client sites with the Block Editor
- Developers using custom fields and dynamic content
Features
Large block library
Essential and advanced blocks come in one plugin, so you can build most layouts in the Block Editor without adding several separate block addons.
Dynamic content
Connect blocks to custom fields and live site data to display personalized content that updates automatically instead of being typed in by hand.
Conditional display controls
Show or hide individual blocks based on user roles, device types or other conditions, which helps tailor pages to different visitors.
Design library and UI kits
Start from ready-made layouts and templates, customize them to fit your brand, and save and manage your own patterns for reuse.
Global design system
Set global styles and settings once and apply them across the whole site, keeping typography, colors and spacing consistent from page to page.
Responsive editing and breakpoints
Preview and adjust designs for desktop, tablet and mobile while editing, and define custom breakpoints when the default screen sizes do not fit.
Motion effects and animations
Add animations and motion effects to blocks to give pages movement and visual interest as visitors scroll and interact.
Full Site Editing support
Works with WordPress Full Site Editing, so you can design entire websites, including templates, within Gutenberg.

Questions about Stackable
Do I need a separate page builder to use this?
No. The plugin works inside the native WordPress Block Editor and adds page builder style design options there. You build pages with its blocks in Gutenberg, and it also supports Full Site Editing for designing whole sites.
Can I show different blocks to different visitors?
Yes. Conditional display controls let you show or hide blocks based on user roles, device types or other conditions, so logged-in members, mobile visitors or other groups can see content suited to them.
Can blocks pull in data from custom fields?
Yes. The dynamic content feature connects blocks to custom fields and real-time site data, which is useful for listings, profiles or any page where the content should come from stored fields rather than manual entry.
How does it handle mobile and tablet layouts?
You can preview and adjust designs for desktop, tablet and mobile while you edit, and set custom breakpoints for your own responsive rules. It also loads appropriately sized images for each device.
Is Stackable free?
The code of Stackable is licensed under the GPL, so anyone may use, change and share it. GPL Feast is a paid service: a plan or a single purchase gives you the download and automatic updates. The developer's own support, licence key and online services are not included.
