This is the most common reason teams migrate away from Builder.io. SvelteKit eliminates this issue entirely.
Complex setup compared to traditional headless CMS
With SvelteKit, svelte compiles to vanilla js — smallest possible bundle sizes.
Free tier is limited — costs grow with page views
Modern architectures like SvelteKit are designed to avoid this from the ground up.
Visual editing can produce inconsistent layouts if not constrained
After migrating, you'll no longer need to worry about this — SvelteKit takes a fundamentally different approach.

Select SvelteKit as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Builder.io to SvelteKit makes the most sense if you're experiencing adds sdk dependency and api calls to your frontend or outgrowing Builder.io's architecture. SvelteKit is best for teams wanting excellent performance with a simpler, more intuitive framework.
You should migrate if: your Builder.io site is slow, your hosting costs are climbing, you need developer flexibility, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your Builder.io site benefits from visual editor works with any framework (react, vue, svelte, etc.) and you don't have JavaScript/TypeScript developers on your team. Builder.io is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Builder.io 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.
