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. SolidStart eliminates this issue entirely.
Performance is poor without server-side caching
With SolidStart, solidjs fine-grained reactivity — updates dom without virtual dom diffing.
Limited developer documentation and community support
Modern architectures like SolidStart 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 — SolidStart takes a fundamentally different approach.
Full-stack framework for SolidJS with fine-grained reactivity. Built with JavaScript/TypeScript (SolidJS), it's performance-focused developers who want react-like syntax without virtual dom overhead.
SolidJS fine-grained reactivity — updates DOM without virtual DOM diffing
Top benchmark performance — often faster than Svelte
JSX syntax makes it approachable for React developers
File-based routing with SSR and SSG support
SolidStart 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 SolidStart
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in SolidStart. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your Concrete5 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 Concrete5 to SolidStart makes the most sense if you're experiencing very small ecosystem compared to other php cms options or outgrowing Concrete5's architecture. SolidStart is best for performance-focused developers who want react-like syntax without virtual dom overhead.
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 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.
