Why Astro for Squarespace migrations
If your Squarespace site is primarily content — a portfolio, a blog, a marketing site — Astro is the better migration target than Next.js. Astro ships zero JavaScript by default. Lighthouse 100 is not a target; it is the baseline.
Squarespace''s biggest performance problem is JavaScript overhead. Moving to Astro eliminates this entirely. Your pages become pure HTML served from a CDN — no platform framework, no unnecessary scripts.
The build process
I extract your Squarespace content (blog XML export + manual page extraction), rebuild your design system in Astro with Tailwind CSS, and connect content to Supabase or Sanity for ongoing management. The result is a site that looks like your Squarespace site but loads in a fraction of the time.

Common questions
Why Astro over Next.js for a Squarespace migration?
If your site is primarily content — portfolio, blog, marketing pages — Astro ships zero JavaScript by default and consistently hits Lighthouse 100. Next.js is better for sites that need complex interactivity or user authentication.
Can Astro handle my Squarespace blog?
Yes. I export your Squarespace blog posts (XML), import them into Supabase or as Astro content collections, and build the blog with the same categories and URL structure.
Will my Squarespace portfolio work in Astro?
Yes. Portfolio galleries, case studies, and project pages rebuild cleanly in Astro. The static generation means every portfolio page is pre-rendered and served from CDN — significantly faster than Squarespace.
How long does Squarespace to Astro take?
A standard Squarespace site (10-20 pages, blog) takes 2-3 weeks. A more complex site with custom sections and large media library takes 4-6 weeks.
What if I need to update content after migration?
I connect Astro to Supabase (for programmatic content) or Sanity (for editor-managed content). You update content through a clean interface and trigger a rebuild via webhook. Changes are live in under 60 seconds.
