Official docs: Astro Documentation
Visual page builder and CMS for React codebases. React teams that want non-developers to edit pages visually, but these limitations push teams toward modern alternatives.
Primarily React-only — limited framework support
This is the most common reason teams migrate away from Plasmic. Astro eliminates this issue entirely.
Steeper learning curve than typical page builders
With Astro, ships zero js to the client by default (islands architecture).
Smaller community and fewer templates available
Modern architectures like Astro are designed to avoid this from the ground up.
Can add complexity to your build pipeline
After migrating, you'll no longer need to worry about this — Astro takes a fundamentally different approach.
Content-focused framework that ships zero JavaScript by default. Built with JavaScript/TypeScript (framework-agnostic), it's content-heavy websites that need maximum performance with minimal javascript.
Ships zero JS to the client by default (Islands Architecture)
Use React, Vue, Svelte, or any framework in the same project
Content collections with type-safe Markdown/MDX
Purpose-built for content sites — blogs, docs, marketing pages
Astro is open-source and free to use. You own your code and data with no vendor lock-in. Deploy to any host that supports JavaScript/TypeScript, or use managed platforms like Vercel and Netlify for zero-config deployments.

A detailed breakdown of how your Plasmic content maps to Astro
What may need manual attention
Visual layouts and custom animations built in Plasmic'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 Plasmic 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 Plasmic to Astro makes the most sense if you're experiencing primarily react-only — limited framework support or outgrowing Plasmic's architecture. Astro is best for content-heavy websites that need maximum performance with minimal javascript.
You should migrate if: your Plasmic 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 Plasmic site benefits from renders into your actual react codebase — no iframes and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your Plasmic 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.
