you want the site on your own hosting, free and open source
Stay with Squarespace if.

- you sell products, services or memberships from the site

Where Squarespace is stronger
Polished, with nothing to maintain.
Squarespace templates look good from day one, and hosting, security, domains and commerce are handled for you under one subscription.
Where Kaleta is stronger
A design system you own.
Kaleta gives you design tokens, shared classes and components on your own hosting, free – and Claude builds pages in that design system as drafts you approve.
Moving over
Moving from Squarespace.
Kaleta imports a Squarespace site by its address: pages, images and blog posts come in, and every old address gets a 301 redirect. The import takes the content, not the template – Claude then reworks each page as a draft from Kaleta sections, in your design system. Squarespace’s WordPress-format export also works with the WordPress importer, though it has not been tested with Squarespace exports. Before you switch the domain, the migration report checks every old address against the new site.
FAQ
Questions from Squarespace users.
Can I import my Squarespace blog?
Yes. Import from a website brings blog posts in as news, with their images and 301 redirects. The WordPress-format export is another route, though it has not been tested with Squarespace exports.
Will my template look the same?
No template is converted. Kaleta has its own starter sites and design system; Claude can match your colours, fonts and layout.
Is Kaleta really free?
Yes. Kaleta is open source under GPL-2.0-or-later. You pay only for your hosting, and for your own Claude plan if you use Claude.
