Official docs: SvelteKit Documentation
In-context editing CMS for marketers. Marketing teams who want to edit pages visually without developer help, but these limitations push teams toward modern alternatives.
Very small ecosystem compared to other PHP CMS options
This is the most common reason teams migrate away from Concrete5. SvelteKit eliminates this issue entirely.
Performance is poor without server-side caching
With SvelteKit, svelte compiles to vanilla js — smallest possible bundle sizes.
Limited developer documentation and community support
Modern architectures like SvelteKit are designed to avoid this from the ground up.
Fewer modern integrations and headless capabilities
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
SvelteKit 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 Concrete5 content maps to SvelteKit
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in SvelteKit. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your Concrete5 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 Concrete5 to SvelteKit makes the most sense if you're experiencing very small ecosystem compared to other php cms options or outgrowing Concrete5's architecture. SvelteKit is best for teams wanting excellent performance with a simpler, more intuitive framework.
You should migrate if: your Concrete5 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 Concrete5 site benefits from true in-page editing — edit content directly on the live page and you don't have JavaScript/TypeScript developers on your team. Concrete5 is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Concrete5 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.
