Visual CMS that integrates with any frontend framework. Teams wanting visual editing on top of a code-based frontend, but these limitations push teams toward modern alternatives.
Adds SDK dependency and API calls to your frontend
This is the most common reason teams migrate away from Builder.io. Astro eliminates this issue entirely.
Complex setup compared to traditional headless CMS
With Astro, ships zero js to the client by default (islands architecture).
Free tier is limited — costs grow with page views
Modern architectures like Astro 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 — Astro takes a fundamentally different approach.

A detailed breakdown of how your Builder.io content maps to Astro
What may need manual attention
Visual layouts and custom animations built in Builder.io's editor will need to be recreated in Astro. The content and text transfers, but the visual design is platform-specific.
Migrate your content in three simple steps
Enter your Builder.io site URL — LeaveWP connects automatically.
Select Astro as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Builder.io to Astro makes the most sense if you're experiencing adds sdk dependency and api calls to your frontend or outgrowing Builder.io's architecture. Astro is best for content-heavy websites that need maximum performance with minimal javascript.
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 Astro, and download your content. The more important question is whether Astro's architecture fits your team's skills and your project's long-term needs.
