From Craft CMS to Builder.io
We are the Craft CMS to Builder.io migration experts

The process
How we migrate from Craft CMS to Builder.io
- 01
Access and gating audit
First we check the existing Craft CMS and see whether the data is clean enough to move straight over to Builder.io, and plan around any auth walls or bot protection in the way.
- 02
Rendering assessment and extraction
Then we work out how Craft CMS renders its pages and pull the content out, even without CMS access.
- 03
AI-assisted sanitization
Everything extracted runs through our sanitization pipeline, which flags slop, normalizes structure, and leaves us clean content to work with.
- 04
Content-model design with the client
Before anything moves, we agree the Builder.io content model with you, shaped around how your editors actually work.
- 05
Transform and soft-migrate
We transform the content to the agreed schema and run a full dry run, so mappings and edge cases prove out before production.
- 06
Execute the real migration
Once the dry run is clean, everything moves into Builder.io in one controlled cutover.
- 07
Redirect mapping and throttled sitemap submission
Every old URL gets mapped to its new home with the right redirect, so rankings and link equity survive the move.
- 08
Agentic-browser QA
Finally, automated browsers sweep the new site for data issues, design regressions, and missing SEO signals.

Challenges with Craft CMS
Key pain points
The elephant in the room is PHP. Craft requires a traditional LAMP-style hosting setup with PHP 8.2+ and MySQL or Postgres, which immediately rules out the serverless and edge-first hosting that modern JavaScript frameworks thrive on. You're managing servers, configuring OPcache, tuning database connections, and dealing with all the operational overhead that comes with self-hosted PHP applications. For teams already working in the JavaScript ecosystem, this is a hard sell.
Major version upgrades are genuinely painful. Craft doesn't support skipping major versions, so migrating from Craft 2 to 5 means stepping through every version in between. Each jump brings breaking changes to Twig templates, PHP requirements, and plugin compatibility. We've seen agencies spend weeks on upgrades that should have been straightforward. The Team tier starts at $279 per project and the Pro tier costs $399, plus $99 annual renewals for both. A free Solo tier exists for single-user projects, but costs still add up for agencies, especially when you factor in plugins and the recent trend toward stricter licence enforcement in the control panel.
The community, while passionate, is relatively small compared to WordPress or even newer headless CMS platforms. When you hit an edge case or need help with a niche plugin, you may find yourself digging through GitHub issues rather than finding a ready answer. And while Craft Cloud exists as a managed hosting option, it's still maturing and doesn't yet match the deployment experience you'd get with platforms like Vercel or Netlify.
PHP hosting requirements
You need a traditional server with PHP 8.2+, MySQL or Postgres, and proper configuration. No serverless, no edge deployment, no modern hosting shortcuts.
Painful major version upgrades
You can't skip major versions, so upgrades mean stepping through each release with breaking Twig, PHP, and plugin changes along the way.
Smaller community and ecosystem
The community is dedicated but small. Finding answers to niche problems often means digging through GitHub issues or waiting on forum responses.
Licence costs add up
The Team tier is $279 per project and Pro is $399, both with $99 annual renewals, plus paid plugins on top. A free Solo tier exists for single-user projects, but costs add up quickly for agencies managing multiple client sites.
Learning curve for non-developers
Craft assumes your team includes developers. Content editors coming from WordPress or simpler tools will need time to adjust to the more structured interface.
Twig templating limitations
Twig is clean but limited compared to modern component frameworks. Complex UI logic gets awkward, and you're locked into whatever Twig version Craft supports.
Benefits of Builder.io
Key advantages
Builder.io occupies a unique spot in the headless CMS landscape. It is not really a traditional headless CMS in the way that Sanity or Contentful are. It is more of a visual page builder with headless capabilities bolted on. That distinction matters because if your marketing team needs to ship landing pages fast without filing Jira tickets, Builder.io genuinely delivers on that promise. The drag-and-drop editor is solid, and the ability to register your own React components so that non-developers can compose pages from your actual design system is a legitimately powerful idea.
Where Builder.io really shines is in bridging the gap between developers and marketing teams. You build the components, register them with Builder, and then hand the keys over. Marketers can assemble pages, run A/B tests, and publish without touching code. For agencies like ours, this means fewer "can you just move this banner" tickets and more time spent on actual engineering work.
The framework support is also genuinely broad. Next.js, React, Angular, Vue, Svelte, Qwik, SolidJS, and React Native all have SDKs. If you are running a modern JavaScript stack, Builder.io probably has an integration for it. The AI features they have been shipping are interesting too, though still early days in terms of real production reliability.
Visual drag-and-drop editor
The visual editor lets non-technical users build and edit pages using your actual codebase components. It is one of the better implementations of visual editing in the headless space.
Custom component registration
Developers can register their own React, Vue, or Angular components so editors drag and drop real design system pieces rather than generic blocks.
A/B testing and personalisation built in
Native experimentation tools let marketing teams run split tests and personalise content without needing a separate optimisation platform.
Broad framework support
SDKs for Next.js, React, Angular, Vue, Svelte, Qwik, SolidJS, and React Native mean you are not locked into a single frontend framework.
Marketing team autonomy
Content and marketing teams can ship landing pages, campaign pages, and promotions independently, which frees up developer time for product work.
Structured and visual content modes
Builder.io supports both structured data models for developer-driven content and visual page building for marketing-driven content, giving teams flexibility in how they work.
Common questions
Craft CMS to Builder.io migration FAQs
Answers to the most common questions about Craft CMS to Builder.io migration
The costs add up quicker than most agencies expect. The Solo tier is free for single-user projects, Team is $279 per project, and Pro is $399 per project. Both paid tiers carry a $99 annual renewal fee. If you're running 10 client sites on Pro, that's $3,990 upfront plus $990 per year in renewals before you've paid for a single plugin. Popular plugins like SEOmatic, Blitz (caching), and Navigation run $99-$199 each. Factor in PHP hosting ($20-$100/month per site depending on traffic) and the total per-project cost lands between $500 and $1,500 in year one. It's reasonable for individual projects but the aggregate cost across a portfolio is where agencies feel the squeeze.
