Headless CMS in 2026: Sanity vs Contentful vs Strapi vs Prismic

The headless CMS market is projected to grow from $3.94 billion to $22.28 billion by 2034, at a compound annual growth rate exceeding 21% (Sanity, February 2026). That growth reflects genuine market demand — businesses increasingly need content that works across websites, mobile apps, and emerging channels simultaneously.

But market growth does not make the buying decision easier. It makes it harder. More vendors, more pricing models, more architectural opinions. And the cost of a wrong choice is not the monthly subscription fee — it is the migration you will need when your content model cannot scale with your business requirements.

This post is a direct comparison of the four platforms we evaluate most often: Sanity, Contentful, Strapi, and Prismic. We use Sanity as our default recommendation and will say so clearly and explain why, but this comparison covers the cases where the others are the correct choice.

What “Headless” Actually Means for Your Business

A traditional CMS like WordPress manages both your content and how it is displayed. Change the presentation layer and you may need to restructure your content. Change your content model and the presentation may break.

A headless CMS separates these concerns. Your content is stored as structured data and accessed via API. Your website, mobile app, or any other channel fetches that data and handles its own presentation. The CMS does not care how content is displayed — it just serves it.

This matters when you need the same content to power multiple channels, when your frontend team wants to work in modern JavaScript frameworks, or when your content requirements are complex enough that HTML-in-a-database creates maintenance problems over time.

The Four Platforms: A Direct Comparison

Sanity

Sanity positions itself as a “content operating system” — treating content as structured data rather than page-based templates. Its defining technical feature is GROQ (Graph-Relational Object Queries), a custom query language that lets developers fetch precisely the data they need in a single request, avoiding the over-fetching problem common with REST APIs (Sanity, January 2026).

Sanity also provides GraphQL and REST if your team prefers standard approaches, but GROQ is the recommended path for its efficiency and expressiveness.

The other standout is Portable Text: rather than storing content as HTML, Sanity stores it as structured data — blocks with explicit types, annotations, and custom objects (Sanity, January 2026). A blog post written in Sanity can be rendered as a website, a mobile app, a PDF, or voice assistant content from the same source. The format is an open specification, so the content is not locked to the platform.

For editorial teams, Sanity’s Studio provides real-time collaboration with presence indicators showing who is working on what. Developers define the schema in TypeScript with full version control — the content model is code, not a web interface configuration.

Pricing starts at $15 per user per month for the Growth plan, with a free tier available for individuals (Sanity, February 2026).

Contentful

Contentful is the enterprise standard. It handles over 4.6 billion delivery requests during peak traffic periods (Contentful, November 2025), which is meaningful evidence of reliability at scale.

Its GraphQL implementation is strong — well-typed with schema introspection that integrates cleanly with modern frontend frameworks. The content modelling approach is primarily web-interface-based: content types and fields configured through a visual editor, though the Contentful Management API and CLI allow code-driven content model management for teams that prefer it. Some teams prefer this separation between content architecture and application code; others find it slower to iterate on than a code-first schema.

Where Contentful clearly leads is enterprise workflow management: custom roles, approval processes, audit logging, and an ecosystem of over 350 integrations through its App Framework. PCI DSS compliance and data residency options make it suitable for regulated industries.

The cost reflects this positioning. The Lite plan starts at approximately $300 per month. Premium plans exceed $500 per month. According to buyer-reported procurement data (Vendr, 2026), large enterprise configurations can reach $79,000 annually before negotiation (G2, 2026).

Strapi

Strapi is the open-source alternative. The core platform is free — no per-user cost, no API request pricing. It generates REST and GraphQL APIs automatically based on your content type definitions.

The trade-off is operational complexity. Because Strapi is self-hosted, your team manages the database, caching, scaling, and security updates. This is appropriate for organisations with significant DevOps capacity who want full infrastructure control and have compliance requirements that prevent storing content on third-party SaaS platforms.

For teams without that capacity, Strapi Cloud offers managed hosting starting at $25 per month for small projects. But at that point the cost-of-ownership calculation changes — you are paying for managed hosting on top of development time to configure and maintain the system, which often brings total cost above Sanity’s per-user pricing for small teams.

Prismic

Prismic takes a different architectural approach entirely. Rather than content-as-data, it is built around a page-building paradigm. Predefined components called Slices can be stacked visually by editors to compose page layouts, defined in code via Slice Machine but used without developer intervention (Prismic, December 2025).

This is powerful for marketing teams that need to create and modify pages independently. It is limiting for content requirements that go beyond the predefined component library, or for cases where the same content needs to render differently across multiple channels.

Pricing ranges from free for individuals to $675 per month for Platinum, with Enterprise plans available (Bejamas, May 2025). The model is based on repository features rather than user seats, which can be economical for larger teams on straightforward projects.

Pricing Comparison

How They Handle Editorial Workflows

This is where the day-to-day experience of editors and developers diverges most significantly.

Sanity’s live preview is the strongest among the four. The Presentation tool allows editors to see exactly how content will render before publishing, inline within the Studio. Multiple team members can edit simultaneously with presence indicators. The platform stores full revision history and supports document-level permissions.

Contentful provides draft/publish workflows with environment-based previews — teams maintain separate preview and production deployments. The preview experience is less integrated than Sanity’s; editors view content in a separate environment rather than inline. However, Contentful’s formal approval processes and audit logging are more mature for large organisations with compliance requirements (Contentful, November 2025).

Strapi’s preview capabilities depend on the frontend implementation. The platform provides draft/publish states, but teams build their own preview infrastructure. Workflow customisation requires development effort beyond the default admin panel.

Prismic offers visual previews through its Page Builder interface. For non-page content types, preview is less straightforward (SaaSworthy, January 2026).

Content Modeling: Where Decisions Have Long-Term Consequences

The way a CMS handles content modeling determines whether your content can evolve with your business requirements — or whether you accumulate technical debt that forces a migration later.

Sanity’s schema-as-code approach is the most flexible. Content types are defined in TypeScript, versioned in git, and can include custom input components directly in the editing interface. This enables highly tailored editorial experiences and content models that match your actual data structure rather than adapting your data to the platform’s assumptions.

Contentful’s web-interface content modeling is predictable and approachable for non-developers who need to configure content types. For complex models, it becomes slower to iterate on than code-based approaches.

Strapi’s dynamic zone and component system enables reusable content pieces across types, with flexibility proportional to development investment.

Prismic’s Slices approach is the most opinionated. It works well within its paradigm and becomes constrictive when requirements exceed what Slices can express.

Asset Management

All four platforms provide image transformation and CDN delivery. Sanity treats assets as structured content — you can query based on metadata like dominant colours, geo-location, and EXIF data. Contentful provides mature asset management with focal point selection, asset tagging, and a strong integration ecosystem for specialised digital asset management tools. Strapi’s asset handling depends on the configured provider — local storage, AWS S3, Cloudinary, or others — requiring configuration. Prismic provides solid asset management with image optimisation, though less comprehensive than Sanity or Contentful.

Which Platform to Choose

Our Default: Sanity — With the Rationale

We use Sanity as our default CMS recommendation for most client projects. The reasoning is direct.

For medium-sized businesses requiring professional websites with moderate-to-high content complexity, Sanity provides the strongest balance of developer experience, content flexibility, and value. GROQ and Portable Text enable sophisticated content architectures without creating platform lock-in. The $15 per user starting price is competitive against Contentful’s $300 per month floor. Real-time collaboration and the Presentation preview tool improve the client experience during content creation.

We have deployed Sanity in production and can verify it handles professional-grade requirements without needing workarounds.

That said, Sanity is not always the right answer. If your organisation has existing Contentful usage, Microsoft 365 integrations that connect to the Contentful ecosystem, or compliance requirements that make Contentful’s data residency options necessary, the higher cost may be justified. If you have a strong DevOps team and compliance constraints that prevent SaaS storage of content, Strapi’s self-hosted model is the correct choice. If your marketing team needs visual page composition without developer involvement and your content requirements are straightforward, Prismic will serve them better than a more developer-oriented tool.

The decision is not about which platform scores highest on a feature comparison matrix. It is about which platform aligns with your team structure, your content requirements, and your growth trajectory over the next three years.

The Practical Recommendation

Start by answering three questions before you evaluate any platform:

1. Who owns content creation — developers or non-technical editors, and how much independence does the content team need?
2. What channels does this content need to power — one website now, or multiple channels over the next two years?
3. What are your compliance and hosting constraints — can you use SaaS, or do you need infrastructure control?

Those answers will narrow the field faster than any feature comparison. The headless CMS market has matured enough that the major platforms all handle the fundamentals well. The differentiation is in fit for your specific context.
