Official docs: Remix 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. Remix eliminates this issue entirely.
Performance is poor without server-side caching
With Remix, built on web standards — forms, headers, and http conventions.
Limited developer documentation and community support
Modern architectures like Remix 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 — Remix takes a fundamentally different approach.
Full-stack React framework built on web standards. Built with JavaScript/TypeScript (React), it's full-stack web applications that benefit from web-standard patterns.
Built on web standards — forms, headers, and HTTP conventions
Nested routing with parallel data loading (no waterfalls)
Excellent error handling with error boundaries at every route
Works on any JavaScript runtime (Node.js, Deno, Cloudflare Workers)
Remix 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 Remix
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in Remix. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your Concrete5 site URL — LeaveWP connects automatically.
Select Remix as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Concrete5 to Remix makes the most sense if you're experiencing very small ecosystem compared to other php cms options or outgrowing Concrete5's architecture. Remix is best for full-stack web applications that benefit from web-standard patterns.
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 Remix, and download your content. The more important question is whether Remix's architecture fits your team's skills and your project's long-term needs.
