Build Website Templates That Launch New Projects Fast
Website templates are imported through the same library format as blocks, but they live in the pageTemplates array and carry a full projectData payload.
The builder expects imported templates inside a functional-websites-library JSON file. Templates live in pageTemplates, and each one contains a full projectData object similar to what the builder stores internally.
Name + Description
This is what users see inside the Custom Library modal.
projectData
This holds the pages, colors, CSS, JS, navbars, and metadata.
Import Once
After import, the template becomes selectable when creating a new website.
Copy And Paste: Minimal Website Template Pack
This example creates one simple starter site with a home page, a hero block, and a CTA block.

What Matters Most In projectData
name and brandName: used as the template identity.
globalCSS: great for reusable styling that should follow the whole template.
meta: useful for SEO defaults and social cards.
brand: the color system used by blocks and generated sections.
pages: at least one page is needed. The first page should usually use slug: "index".
blocks: these are standard builder blocks like hero, section, heading, cta, and more.
Fastest Workflow For Making New Templates
Build a site in the builder until the layout feels right.
Save the current page as a website template from the Custom Library tools.
Export your library bundle.
Open the exported JSON and duplicate the template object.
Rename it, tweak projectData, and re-import it as a pack.
