Claude CMS vs Squarespace
Squarespace builds beautiful templates. Claude CMS builds exactly what you describe — with custom code, server-side logic, and a price tag Squarespace can't match.
Squarespace is a hosted template platform with no server-side access and no custom PHP. Claude CMS is a self-hosted PHP/MySQL system built and managed entirely through Claude via MCP.
Templates vs conversation
Platform-hosted template engine vs self-hosted MCP-native CMS
Squarespace gives you a drag-and-drop editor with polished templates. Claude CMS gives you a conversation. Describe what you want — Claude builds it. Any layout, any feature, any design.
Squarespace is a closed SaaS with a proprietary template language, no raw PHP, no SSH access, and no database access. Claude CMS exposes your entire LAMP stack through MCP tool endpoints that Claude invokes directly.

Is Claude CMS right for you?
Migration candidates
You've hit Squarespace's limits
You need a custom form that stores data, a booking system, an API integration, or any feature that requires server-side code. Squarespace can't do it — Claude CMS can.
You need PHP execution, direct DB access, or webhook handling. Squarespace's Code Injection blocks are client-side only — no server logic, no sessions, no file I/O.
You're tired of the bill
You're paying £13–£35+/month for a Squarespace plan and your site is a few pages. Claude CMS at £6.99/month covers unlimited pages, features, and integrations.
Squarespace Business starts at £23/month — over £270/year for a site that still blocks server-side logic. Claude CMS at £6.99/mo gives you a full LAMP stack.
You want to own your site
If Squarespace raises prices, removes features, or shuts down — your site goes with it. Claude CMS runs on your hosting. You own it completely.
Squarespace export gives you unstyled HTML with no CMS. Claude CMS is plain PHP/MySQL — switch hosts anytime, cancel the licence, and the site still serves pages.
How to move from Squarespace
Migration workflow
You don't need to start from scratch. Claude can recreate your existing pages in Claude CMS — often in a single conversation.
Export your Squarespace site to get the HTML structure and content. Claude uses this as source material to build equivalent pages via site_create_page with improved markup and structured data.
Export your content
Use Squarespace's export tool to download your pages. This gives you the raw content to migrate.
Settings → Advanced → Export. Produces an XML file with page content. Images need manual download via the Media Manager.
Set up Claude CMS
Install Claude CMS on your hosting and connect it to Claude. Takes around 10 minutes.
Deploy to any PHP 7.4+/MySQL 5.7+ host. Run install.php, add the MCP connector to Claude, verify the connection.
Rebuild with Claude
Share your existing pages with Claude and it recreates them — with a custom design, better SEO, and any improvements you want.
Paste exported HTML into Claude. It maps content to site_create_page calls, rewrites markup to your new design system, and adds JSON-LD and meta.
Point your domain
Update your domain's DNS to point to your new hosting. Your site is live and Squarespace is cancelled.
Update A/CNAME records at your registrar. Set up SSL (Let's Encrypt or host-provided). Cancel Squarespace. Done.
