Contentful vs Sanity vs Storyblok: A Practical Comparison for Modern Web Development

Contentful vs Sanity vs Storyblok (at a Glance)

All three platforms are capable and scalable, but they approach content management differently. Here's how.

Pricing and Scalability

Contentful's pricing follows a tiered SaaS structure. The free Community plan is generous to start, but costs jump significantly from there. The Team plan runs around $489/month, which can become challenging for growing agencies or multi-site organisations.

Storyblok sits in the middle ground. It starts at around $99/month (with a free Starter plan for small projects), making it more accessible than Contentful at entry level. That said, costs can climb unexpectedly. The platform's tiered structure means exceeding limits on images, locales, or users can push you into a higher plan faster than you'd expect.

Sanity uses a usage-based pricing model. You can start for free and pay only for what you use: API calls, bandwidth, and the like. For content-heavy, high-traffic sites, this tends to be the most predictable and scalable option.

✅ Best for predictable scaling: Sanity
✅ Best for mid-market entry pricing: Storyblok
✅ Best for early-stage simplicity: Contentful

Editor Experience

Contentful offers a clean, polished interface that works well for marketing teams who want minimal setup. Editors can get going quickly, but the layout and content structures are largely fixed. What you see is what you get, and that might not always be enough.

Storyblok's headline feature is its visual editor. Editors can see a live preview of their content as they're editing it, which closes the gap between what's in the CMS and what appears on the page. This is genuinely excellent for marketing teams managing landing pages, campaigns, or editorial content, and it's where Storyblok clearly differentiates itself from both competitors.

Sanity offers the Sanity Studio, which can be tailored to match exactly how your team works. Custom input fields, layouts, and validation rules; all defined in code. It's the most powerful option, but it requires developer time to set up well.

✅ Best for simplicity and quick onboarding: Contentful
✅ Best for non-technical editors who want visual context: Storyblok
✅ Best for customised workflows and advanced use cases: Sanity

Content Modelling and Structure

This is where the three platforms diverge most sharply.

Contentful uses a UI-driven model. Editors and developers define content types and relationships directly in the app. It's fast to get started but can become restrictive when managing complex, nested content.

Storyblok uses a component-based model built around "Bloks". Reusable content blocks that mirror your frontend components. Schema management happens in the UI, which keeps things accessible for non-developers. The trade-off: schemas aren't version-controlled in Git, which creates friction for development teams with CI/CD workflows.

Sanity models content in code (JavaScript/TypeScript schemas). This gives developers total control and allows for dynamic relationships, deeply nested content, and reusable components; all version-controlled in Git. Again, the big dependency is developer support. Without it, you can't unlock the full potential of the platform.

✅ Best for simple websites or marketing pages: Contentful
✅ Best for component-driven teams wanting some flexibility: Storyblok
✅ Best for scalable, complex architectures: Sanity

Localisation and Multi-Region Support

All three platforms support multilingual and multi-region content, but each takes a different approach.

Contentful uses field-level localisation, meaning every field can carry multiple language versions. This works well for straightforward translation workflows and is backed by a mature localisation API. It can become unwieldy at scale, though.

Storyblok uses folder and slug-based localisation, and also includes built-in AI translation tools. For teams managing multiple language versions of marketing content, this is a strong proposition. Especially where editors want to handle translations without leaving the platform.

Sanity allows global and local content layers, meaning editors can decide what content should be shared or regionalised. This makes it the most flexible option for enterprises managing large volumes of content across multiple brands or countries.

✅ Best for straightforward language toggling: Contentful
✅ Best for editor-led multilingual workflows: Storyblok
✅ Best for advanced regional strategies: Sanity

Developer Experience

Developers tend to love Sanity for its flexibility and modern tooling (this is also our experience after years of working with different tools). It's built on React, integrates seamlessly with Next.js, Nuxt, and Vercel, and GROQ lets you query content exactly as you need it without over-fetching.

Storyblok sits in the middle. It offers solid framework-specific SDKs (Next.js, Vue, Nuxt, Astro) and supports both REST and GraphQL. The component-based model translates well to modern frontend development patterns. The main friction point for developer teams is the UI-based schema management. Because schemas live in the Storyblok interface rather than in your codebase, you lose Git-based version control and the clean CI/CD workflows most modern teams expect.

Contentful provides solid REST and GraphQL APIs and a polished SDK ecosystem. It's less flexible than either alternative but requires less setup, making it appealing to teams that value convenience over control.

✅ Best for rapid setup and plug-and-play integration: Contentful
✅ Best for balanced developer/editor experience: Storyblok
✅ Best for custom frontends and full developer control: Sanity

Hosting and Architecture

Contentful is entirely hosted. You can't self-host or version the backend.

Storyblok is also fully managed. Schemas, Studio, and content all live in Storyblok's cloud. There's no self-hosting option, and as noted, schema changes don't live in your codebase.

Sanity gives you a choice to either use their managed hosting, or self-host the Sanity Studio. All configurations live in Git, enabling CI/CD workflows, environment parity, and cleaner versioning across your whole team.

✅ Best for teams who want to avoid dev-ops complexity: Contentful or Storyblok
✅ Best for teams that value flexibility and control: Sanity

Company Vision and Ecosystem

All three companies are well-established and continuing to grow.

• Contentful, founded in 2013, is a Berlin-based company with a large enterprise customer base (Nike, Spotify, and others). It's one of the most established names in the space.
• Storyblok, founded in 2017 in Austria, raised $47M in 2022 and has grown rapidly off the back of its visual editor. It counts Virgin Media O2, Oatly, and TomTom among its users.
• Sanity, founded in 2015 in Norway, raised $39M in 2021 and is known for its open-source approach and active developer community.

All three are stable choices. Where Sanity has the edge in terms of future-proofing is its open, composable ethos, it resonates strongly with modern frontend ecosystems and gives the adaptability to meet an ever-changing technical landscape. Storyblok is betting on the visual editor as the future of content management, which has genuine appeal for editor-heavy organisations. Contentful continues to invest in enterprise reliability and governance.

AI Capabilities and Integration

AI is moving fast in the CMS space, and all three platforms are responding in their own way. The question is no longer "does it have AI features?", it’s whether those features are genuinely useful for editors, and whether the platform is architected to support the AI tools your team actually wants to bring in.

Contentful's AI offering centres on its AI Content Generator, available as an app in the Contentful Marketplace. It sits inside the editor interface and can generate and rewrite text fields based on prompts, pulling context from your content model. For editors who want to produce first drafts or adapt existing copy without leaving the CMS, it's a reasonable starting point.

The more interesting capability is Contentful's AI Actions, which allows teams to define reusable AI-powered automations. Things like auto-summarising entries, extracting SEO fields, or generating structured content on demand. These are configured without code and can be triggered by editors directly.

For custom AI integration, Contentful's REST and GraphQL APIs make it straightforward to pipe content into external AI pipelines. That said, the schema lives in a UI rather than in your codebase, which limits how tightly you can tie content structure to AI workflows without friction at the configuration layer.

Storyblok has moved quickly on AI. Its AI translation feature is the most practically useful out of the box feature. Editors can trigger translations across multiple locales directly from the interface, which is a meaningful time-saver for multilingual marketing teams.

Beyond translation, Storyblok has integrated AI writing assistance tools into its visual editor, letting editors generate and refine content in context, with a live preview alongside, which is a great example of how editorial AI should work. For non-technical teams, this is probably the most accessible AI experience of the three.

On the integration side, Storyblok's webhook and API system allows custom AI services to connect in, but because schemas are managed in the UI rather than in code, building deeply structured AI pipelines around your content model requires more manual configuration. It works, but the developer experience isn't quite as clean as it could be.

Sanity's approach to AI is the most composable of the three, which is both its strength and its caveat.

There are no AI features switched on by default. Instead, Sanity gives you the building blocks to wire in exactly what you need. The most significant of these is Sanity's native integration with AI input components: you can build custom input fields in Sanity Studio that call out to AI services, whether that's OpenAI, Anthropic, or your own models, and surface the results directly in the editor interface. This means you're not constrained to a platform vendor's AI tooling; you're building the exact editorial AI experience your team needs.

For developers building content-heavy products, this matters. A media company might want AI-assisted tagging and transcription inline in the editor. An e-commerce brand might want product description generation that's aware of brand tone and existing catalogue content. Sanity's code-first schema model means you can shape the AI experience around your data structures rather than retrofitting it around a fixed UI.

The Sanity ecosystem also includes community-contributed AI plugins and growing first-party support for AI-powered workflows. Sanity's GROQ query language makes it straightforward to build retrieval pipelines over structured content, which is increasingly relevant for teams building RAG (Retrieval-Augmented Generation) applications on top of their content.

The trade-off, as ever with Sanity: none of this comes for free. You need developer resource to build it. The out-of-the-box AI experience is intentionally minimal; the custom-built experience can be exceptional.

Our Experience: Why We Typically Choose Sanity

At Represent, we've built with Contentful and Sanity extensively, and in the past also been an official Storyblok partner. Both Storyblok and Contentful hold a big appeal for organisations where marketing teams need speed and visual autonomy without relying on developers for every change.

That said, Sanity consistently performs better for the complex, composable architectures we're asked to build. While it's not the right choice for every business, it's the closest we've come to a "one size fits all" CMS, at least for the kinds of projects we take on.

For example, we once replaced four separate CMS systems for a large Norwegian corporation with a single Sanity implementation, resulting in streamlined workflows and faster deployment.

That doesn't mean Contentful or Storyblok are "bad." In fact, they’re great options, just for different needs:

Contentful tends to be the right fit for:

• Marketing-led teams who want minimal configuration
• Projects with tight deadlines or limited development resources
• Organisations happy to trade flexibility for simplicity

Storyblok tends to be the right fit for:

• Teams where editors need visual confidence and live preview
• Mid-market organisations that want flexibility without full developer dependency
• Projects with meaningful multilingual needs and limited translation tooling

We choose Sanity when:

• Custom workflows or data models are key
• Clients need multi-region, composable architectures
• Developers want full control and scalability

We’ve responded to the top 20 most asked questions about Sanity CMS, it’s worth a read if you’re considering Sanity as your CMS.

Now it's up to you: Contentful, Storyblok, or Sanity?

All three are strong contenders in the headless CMS space. Your best choice depends on your team's workflow, technical expertise, and growth plans.

If you're seeking a CMS that grows with your business, allows deep customisation, and empowers both developers and editors, Sanity is our preferred option. If you need a strong visual editing experience and don't have dedicated developer resource to build out a custom Studio, Storyblok deserves serious consideration.

That said, we always start with the problem, not the platform. If you're unsure, we'll always give honest and transparent advice to help guide you toward the right fit. Let's have a chat.
