Headless CMS with page management built in. Teams wanting headless CMS with traditional page/sitemap management, but these limitations push teams toward modern alternatives.
Smaller community and ecosystem than major headless CMS options
This is the most common reason teams migrate away from Agility CMS. 11ty eliminates this issue entirely.
No free tier — requires paid subscription from day one
With 11ty, ships zero javascript to the browser by default — pure html.
Limited documentation compared to Contentful or Sanity
Modern architectures like 11ty are designed to avoid this from the ground up.
Fewer framework integrations available
After migrating, you'll no longer need to worry about this — 11ty takes a fundamentally different approach.
Zero-config JavaScript SSG that ships zero client JS by default. Built with JavaScript (multiple template languages), it's performance-focused sites that need minimal client-side javascript.
Ships zero JavaScript to the browser by default — pure HTML
Supports 10+ template languages (Nunjucks, Liquid, Markdown, etc.)
Framework-independent — use any or no JS framework
Fast builds and simple mental model
11ty 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, or use managed platforms like Vercel and Netlify for zero-config deployments.

A detailed breakdown of how your Agility CMS content maps to 11ty
What may need manual attention
Custom server-side logic, third-party integrations, and platform-specific plugins will need equivalent solutions in 11ty. The core content (text, images, metadata) transfers cleanly.
Migrate your content in three simple steps
Enter your Agility CMS site URL — LeaveWP connects automatically.
Select 11ty as destination and choose content options.
Download your migrated content or preview it in your browser.
Migrating from Agility CMS to 11ty makes the most sense if you're experiencing smaller community and ecosystem than major headless cms options or outgrowing Agility CMS's architecture. 11ty is best for performance-focused sites that need minimal client-side javascript.
You should migrate if: your Agility CMS 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 Agility CMS site benefits from page management and sitemap built into the headless cms and you don't have JavaScript developers on your team. Agility CMS is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Agility CMS URL, select 11ty, and download your content. The more important question is whether 11ty's architecture fits your team's skills and your project's long-term needs.
