Headless CMS Options Compared: Sanity, Contentful, Strapi and Headless WordPress

Choosing a headless CMS is less about which platform is "best" and more about which platform fits your team, your content complexity, and your budget. We have built on all of the major options below for client projects, and each one has a genuinely different personality once you get past the marketing pages. This is a buyer's comparison, not a vendor ranking, and it includes where each platform tends to disappoint clients as much as where it shines.

Sanity

Sanity is a developer-favorite headless CMS built around a structured content approach and a highly customizable editing environment called Sanity Studio.

Pricing. Sanity's free tier covers small projects reasonably well (up to 3 users, generous API request limits for low-traffic sites). Paid plans start around $15 to $20 per user per month, and usage-based costs kick in around API requests, bandwidth, and asset storage once you scale past a few hundred thousand monthly document reads. Costs stay predictable for small to mid-size sites but can climb for high-traffic, content-heavy builds.

Content modeling. This is Sanity's strongest area. Content schemas are defined in code, giving developers precise control over field types, validation, and relationships between content types. This flexibility is why agencies frequently choose it for complex, custom content structures.

Editor experience. Sanity Studio is genuinely pleasant for editors once configured, and it supports real-time collaborative editing similar to Google Docs, which is unusual among CMS platforms. The catch is that the studio needs deliberate configuration by a developer to feel intuitive. Out of the box, it can feel a bit raw to non-technical users.

Localization. Solid, with field-level internationalization support, though it requires upfront schema planning to work smoothly across many languages.

Self-hosting vs SaaS. Sanity is SaaS-hosted for the backend infrastructure, though the studio interface itself can be deployed anywhere. There is no fully self-hosted option if data residency is a hard requirement.

Developer ecosystem. Strong and growing, with excellent documentation and a genuinely helpful community, though it is smaller than Contentful's enterprise footprint.

Migration risk. Moderate. Content is stored in a proprietary but well-documented format (GROQ-queryable JSON), and export tooling exists, but moving away means rebuilding schemas elsewhere.

Contentful

Contentful is one of the most established enterprise headless CMS platforms, with a strong presence among larger organizations.

Pricing. Contentful's free tier is limited (roughly 5 users, 2 locales), and its paid tiers scale quickly in price, often starting in the hundreds of dollars per month and climbing into the thousands for enterprise features like multiple environments and higher API limits. This is the most expensive option on this list at scale.

Content modeling. Flexible and mature, with a visual schema builder that does not require touching code to define content types, which is friendlier for mixed technical and non-technical teams managing the data model together.

Editor experience. Clean and enterprise-polished, with role-based permissions, approval workflows, and scheduled publishing built in without extra configuration. This maturity is a major reason large organizations pick Contentful over younger platforms.

Localization. One of the strongest localization systems available, built specifically for organizations managing content across many markets and languages simultaneously.

Self-hosting vs SaaS. SaaS only. There is no self-hosted version, which matters for organizations with strict data governance requirements.

Developer ecosystem. Large, with extensive integrations, a mature app marketplace, and broad framework support.

Migration risk. Higher than most alternatives. Contentful's content model and rich text format are fairly proprietary, and its pricing structure makes vendor lock-in a real long-term cost consideration.

Strapi

Strapi is an open-source headless CMS that you self-host (or run through Strapi's managed cloud), giving it a fundamentally different cost and control profile.

Pricing. The self-hosted community edition is free aside from your own server hosting costs, typically $10 to $50 per month for small to mid-size traffic on standard cloud hosting. Strapi Cloud, the managed option, starts around $29 per month and scales from there. This makes Strapi the most budget-friendly option for teams with development resources.

Content modeling. Flexible and code-accessible, with a visual content-type builder in the admin panel plus the ability to extend everything through custom code, since you own the entire backend.

Editor experience. Functional and improving with each release, though it feels less refined than Sanity or Contentful out of the box. Custom fields and workflow automation require plugin development.

Localization. Supported natively, with reasonable configuration options for multi-language content.

Self-hosting vs SaaS. This is Strapi's defining trait. Full self-hosting gives complete control over data residency, infrastructure, and cost, but it also means your team (or your agency) owns server maintenance, security patching, and uptime.

Developer ecosystem. Active open-source community, plugin marketplace, and being Node.js based, it fits naturally into JavaScript-heavy development stacks.

Migration risk. Low. Since you control the database and the codebase directly, exporting content is straightforward compared to SaaS platforms that gate data behind API rate limits.

Headless WordPress

Running WordPress in headless mode keeps the familiar WordPress editor and plugin ecosystem while replacing the theme layer with a modern front end connected through the REST API or WPGraphQL.

Pricing. Very low if you already have WordPress hosting, typically $10 to $40 per month for hosting, plus development cost to build the decoupled front end. This is the cheapest path for organizations with existing WordPress content and editorial habits.

Content modeling. Limited compared to purpose-built headless platforms. Custom fields via Advanced Custom Fields (ACF) work well for moderate complexity, but WordPress's underlying post-and-page structure was not designed for the kind of deeply structured content that Sanity or Contentful handle natively.

Editor experience. This is headless WordPress's biggest selling point. Editors keep the exact interface they already know, including Gutenberg blocks, with zero retraining required.

Localization. Handled through plugins like WPML or Polylang, which work but add another dependency and cost layer rather than being built in.

Self-hosting vs SaaS. Fully self-hosted by default, with managed WordPress hosting options (WP Engine, Kinsta) available if you want less server management.

Developer ecosystem. Enormous, simply by virtue of WordPress's market share, though headless-specific tooling (WPGraphQL, faust.js) is a smaller, more specialized subset of that ecosystem.

Migration risk. Low to moderate. WordPress content exports well in general, though heavily plugin-dependent sites can lose functionality that needs to be rebuilt elsewhere.

Payload and Storyblok, Briefly

Payload is a newer, open-source, TypeScript-native headless CMS that self-hosts like Strapi but with a more modern developer experience and built-in authentication and access control. It suits technical teams who want full code ownership and are comfortable with a younger ecosystem that has less community support than Strapi's.

Storyblok occupies a middle ground with a visual, component-based editor that gives marketers something closer to drag-and-drop page building than most headless platforms, while still exposing structured content through an API. Pricing starts around $99 per month for small teams and rises from there. It is worth serious consideration for teams that want headless flexibility without fully losing visual editing.

Recommendations by Scenario

Small Marketing Team, Limited Technical Staff

Storyblok or headless WordPress tend to work best here, since both preserve a visual, familiar editing experience. If budget is the deciding factor and there is no existing WordPress content, Storyblok's component-based editor is the friendlier learning curve.

Enterprise With Many Locales

Contentful remains the strongest fit for organizations juggling a dozen or more locales, approval chains, and multiple brand sites, despite the higher price tag. The localization tooling and governance features are genuinely built for this scale in a way the alternatives are not.

Budget-Constrained With Technical Staff In-House

Strapi or Payload make the most sense. Both eliminate the recurring SaaS fee that scales with usage, at the cost of owning your own hosting and maintenance. This is often the right call for a startup with an in-house developer and a tight runway.

Existing WordPress Content, Editors Who Refuse to Change Tools

Headless WordPress is the obvious answer. You keep the editorial workflow your team already knows, and the front end gets rebuilt independently. This is one of the more common projects our headless CMS development team takes on, precisely because it avoids retraining an entire marketing team.

Whichever platform looks right on paper, the real determining factor is usually your content model complexity and your team's technical comfort level, not a feature checklist. We typically start full-stack development engagements with a short content audit before recommending a specific platform, because guessing wrong here is expensive to undo later. You can see how these platforms show up in real client work across our portfolio.

FAQ

Can I switch headless CMS platforms later if I choose wrong?

Yes, but it is not trivial. Content and media generally export in usable formats from all six platforms above, though the effort to remap content models and rebuild editor workflows in a new platform typically runs 3 to 8 weeks depending on content volume and how customized your original schema was.

Do these platforms handle ecommerce product data well?

Sanity, Contentful, and Strapi can all model product data, but none of them are ecommerce platforms. Most teams pair a headless CMS with a dedicated commerce backend (Shopify, a custom API) for transactional data, and use the CMS purely for marketing and editorial content layered around the products.

Is a self-hosted option like Strapi or Payload actually cheaper overall?

It is cheaper on the recurring subscription line, but not free. You are trading SaaS fees for server costs, security patching, and uptime responsibility, either handled in-house or through an agency retainer, which typically runs $200 to $800 per month depending on traffic and complexity.

Which platform is easiest for a non-technical marketer to learn?

Headless WordPress and Storyblok are the friendliest for non-technical editors, since both offer visual, page-like editing experiences. Sanity and Contentful are learnable but feel more like filling out structured forms than building a page.

Picking the wrong platform is an expensive mistake to reverse once your team has built workflows around it, so it is worth getting a second opinion before committing. Book a free 1-hour strategy call with our team and we will help you match the right platform to your actual content and budget.
