All-in-one website builder with designer templates. Non-technical creators who want a polished site without touching code, but these limitations push teams toward modern alternatives.
Walled garden — no code access or custom server logic
This is the most common reason teams migrate away from Squarespace. SvelteKit eliminates this issue entirely.
Cannot self-host or export to another platform easily
With SvelteKit, svelte compiles to vanilla js — smallest possible bundle sizes.
Limited to Squarespace's template system for design
Modern architectures like SvelteKit are designed to avoid this from the ground up.
Monthly costs add up ($192-588/year) for a content site
After migrating, you'll no longer need to worry about this — SvelteKit takes a fundamentally different approach.
Full-stack Svelte framework with SSR and SSG. Built with JavaScript/TypeScript (Svelte), it's teams wanting excellent performance with a simpler, more intuitive framework.
Svelte compiles to vanilla JS — smallest possible bundle sizes
Intuitive syntax — easier to learn than React or Vue
Excellent developer experience with fast HMR
File-based routing with SSR, SSG, and SPA modes

A detailed breakdown of how your Squarespace content maps to SvelteKit
What may need manual attention
Visual layouts and custom animations built in Squarespace's editor will need to be recreated in SvelteKit. The content and text transfers, but the visual design is platform-specific.
Migrate your content in three simple steps
Enter your Squarespace site URL — LeaveWP connects automatically.
Select SvelteKit as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Squarespace to SvelteKit makes the most sense if you're experiencing walled garden — no code access or custom server logic or outgrowing Squarespace's architecture. SvelteKit is best for teams wanting excellent performance with a simpler, more intuitive framework.
You should migrate if: your Squarespace site is slow, your hosting costs are climbing, you need more control over your code, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your Squarespace site benefits from beautiful, professionally designed templates out of the box and you don't have JavaScript/TypeScript developers on your team. Squarespace is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Squarespace URL, select SvelteKit, and download your content. The more important question is whether SvelteKit's architecture fits your team's skills and your project's long-term needs.
