Greatest invention since Gutenberg’s printing press, 1440.
Best Website Builder Inside WordPress. Claude AI-Ready.
Von Block is a WordPress plugin that lives inside the default Block Editor. Powered by a lightweight CSS framework, without the page-builder bloat.
Build your website visually, connect Claude via MCP and let AI do the work, or combine both. You’re always in control.
Figma-like grid precision. Design with margins, columns, and gutters (MCG) — the same layout principles your designers use — for pixel-precise layouts across every breakpoint.
Four reasons, officially stamped
Built to Rule
Runs fast
And runs inside the default WordPress Block Editor.
Is light
Everything compiles into one lean CSS file, with no page-builder runtime to load.
Claude-able
Use Claude to design, build and rework whole pages in minutes.
Free rides
Register your domain in one click. Early birds pay nothing until 2028.
The Early Bird Licence
Early birds fly free
Register your domain before 1 January 2027 and Von Block is free until 1 January 2028, every subdomain included. Registering takes one click in the plugin: no checkout, no card.
From 1 January 2027, new registrations are free for 6 months, then 30 USD a year plus VAT.
The Block Editor, fortified
Rule your website without clicking a thousand buttons and no sidebar squeezing your canvas
Von Block opens in its own pop-up window. Drag it to a second monitor and the Block Editor keeps its full width for a true preview, while you give any block layout, spacing and typography from your own framework. What you see in the editor is exactly what your visitors get.
And it loves the keyboard. Type a command instead of hunting for a setting, and once your fingers know the way you adjust blocks at a speed no mouse can match.
Lightweight
Light as a meringue, sturdy as Schönbrunn
Von Block compiles your settings into one lean stylesheet of utility and composite classes. There is no builder runtime between your visitors and your content, so pages stay quick.
Prompt, don’t program
Speak your wish and watch the palace build itself
Tell Claude what you want in plain words. Through the Von Block connector it lays out the sections, sets spacing and typography from your own framework and fills in the content, block by block, right in your WordPress. Something not quite right? Just say so and it is reworked in seconds. You never write a single line of code.
Registered from the comfort of your own palace
There is no shop on this site. You register Von Block inside the plugin, directly from your WordPress installation, in one click and for free. One registration covers your domain and every subdomain: shop, blog, staging and all their cousins.
The imperial toolbox
“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.”
— Antoine de Saint-Exupéry, French writer and aviator, author of The Little Prince
Runs directly in the WordPress Block Editor
Works directly in the default WordPress editor. No shortcodes, no proprietary canvas, just blocks with classes.
Understands Figma-like grid MCG units
Columns, margins and gutters for every breakpoint, as classes like width-c6 and as CSS variables.
Responsive typography styles
Define headings, text and buttons once, hover states included, and reuse them everywhere.
Utility classes, composite classes and custom styles
Bundle repeating patterns such as cards, buttons and sections into one reusable class.
Unbeatable speed at setting up responsive layouts
Each class carries its band: md-width-c12 stacks a row on phones. No media queries by hand.
Claude builds it with you
Describe the page you want and Claude builds it with the framework. Then fine-tune it by hand, or just keep prompting.
MCP connector included*
Let Claude build the website for you
Every Von Block site includes the Von Block MCP connector. Connect it to Claude and describe the page you want: Claude reads your framework, builds the sections with your classes and checks the layout at every breakpoint.
The result is ordinary blocks in the Block Editor, ready for you to tweak and publish.
* The MCP connector runs through your own Claude subscription.

Questions from the court
What exactly is Von Block?
A WordPress plugin with a lightweight CSS framework: a grid, breakpoints, utility classes, composite classes and typography styles that you define once and use on any block in the editor.
Does it replace the WordPress Block Editor?
No. It works directly in the default Block Editor. Your pages stay standard WordPress blocks, with Von Block classes added to them.
How do I get a licence?
There is no order process on this site. Download and install the plugin, open its settings page in WordPress and register your domain there, for free.
What does a registration cover?
One registration covers a domain and all its subdomains, such as example.com, shop.example.com and staging.example.com. Register before 1 January 2027 and it is free until 1 January 2028. From 1 January 2027, new registrations are free for 6 months, then 30 USD a year.
What happens if I don’t register or don’t license?
Von Block works fully either way, with nothing switched off, and your pages and content stay yours. An unregistered site only shows its visitors a small notice that it runs an evaluation copy. Registering removes it.
When a domain’s free period or licence ends, nothing changes for a grace month, and the plugin reminds you in WordPress before and after the end date. After the grace month, visitors see a small notice that the site uses an unlicensed copy, until you license the domain.
How does Claude build my website?
The included MCP connector lets Claude read your framework and create or edit pages with it. It adds sections, applies classes and checks the layout at every breakpoint. You review and publish.
Is it really from 1440?
Gutenberg printed with movable type around 1440. We kept the idea of reusable pieces, and simply swapped the lead letters for blocks.
