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. SolidStart eliminates this issue entirely.
Cannot self-host or export to another platform easily
With SolidStart, solidjs fine-grained reactivity — updates dom without virtual dom diffing.
Limited to Squarespace's template system for design
Modern architectures like SolidStart 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 — SolidStart takes a fundamentally different approach.

A detailed breakdown of how your Squarespace content maps to SolidStart
What may need manual attention
Visual layouts and custom animations built in Squarespace's editor will need to be recreated in SolidStart. 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 SolidStart as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Squarespace to SolidStart makes the most sense if you're experiencing walled garden — no code access or custom server logic or outgrowing Squarespace's architecture. SolidStart is best for performance-focused developers who want react-like syntax without virtual dom overhead.
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 SolidStart, and download your content. The more important question is whether SolidStart's architecture fits your team's skills and your project's long-term needs.
