From Contentful to Builder.io
Last verified:
Key pain points
Contentful is one of those platforms where the bill can catch you off guard. The free tier caps you at 25 content types and 100K API calls, and a single marketing site can blow past both without warning. The next step up is $300 a month, and enterprise pricing often lands in the $50K to $100K+ a year range.
Users on Reddit regularly flag the same thing: tier jumps are forced by hitting one limit, not by needing the bigger feature set. Content model caps alone can push you into a higher plan you don't otherwise need.
The other issue is that Contentful has strong opinions about how content should be modelled, and those opinions aren't always documented. Projects built without that knowledge tend to accumulate performance problems and awkward workarounds. Before writing Contentful off, speak to us, a lot of the pain we see is implementation, not platform.

Pricing climbs fast
Contentful isn't a cheap CMS. Once you pass the free tier's content type or API call limit, you're on the $300/month Lite plan, and enterprise pricing often starts at $50K+ a year.

Complex for non-technical users
Marketers and editors may need a small learning curve before they feel at home. It’s powerful but not always plug-and-play.

Integration dependency
A lot of magic happens through third-party tools. Great for flexibility, but it does mean extra setup instead of getting everything out-of-the-box.

Limited native features
Contentful keeps the core CMS clean and minimal, but that also means more building and configuring to get advanced functionality.

Learning curve for new teams
If your team is moving from a traditional CMS, expect some onboarding time. Structured content is amazing but new for many.

Requires careful management
Because it’s so flexible, projects need good governance. Without it, content models can get messy and harder to maintain over time.
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.
