Headless CMS Comparison: Which Fits Your Content Team

Every content team eventually asks the same question: is the CMS we have holding us back, and if we switch, to what? The four platforms that dominate the shortlist in 2026 are Strapi, Contentful, Sanity and Payload, and they trade against each other on four axes that matter more than feature count. This is what we tell clients when they arrive at the platform implementation conversation with a shortlist and no criteria.

TL;DR

• There is no best headless CMS. There is a best fit for your hosting model, extensibility needs, licence sensitivity and editor experience.
• Strapi wins on self-hosting and ownership. It loses on managed editor polish.
• Contentful wins on managed editor experience. It loses on licence cost at scale.
• Sanity wins on structured content and real-time collaboration. It loses on simplicity.
• Payload wins on developer ergonomics and modern stack. It loses on maturity and third-party ecosystem.

The four questions that decide it

Skip the feature matrices. Four answers narrow four options to one or two, and each of them comes out of your team's constraints rather than a vendor demo.

1. Where does the content live? If data residency or licence terms mean it must stay in your infrastructure, the managed-only options are out before you compare anything else.
2. How extensible does it need to be? Custom fields and validation are table stakes. Custom workflows, custom relationships and inline custom code narrow the field.
3. How much are you willing to pay, at what volume? Per-user and per-entry pricing is fine at low volume and painful at scale.
4. Who is the primary editor? A marketing team wants a Google Docs feel. A developer team is happy with a JSON tree. The wrong choice loses editors long before it loses developers.

The comparison

Where each one wins

Strapi

The default when you want to self-host the CMS or when licence sensitivity matters. Strapi v5 is a large step forward in editor UX, so the historical criticism of "developer-first, editor-second" is less true than it was two years ago. The extensibility is genuine: the plugin system, the customisable admin panel and the ability to write custom controllers and services make it the easiest of the four to adapt to a specific workflow. Our Strapi CMS service covers what a full implementation looks like.

It loses to Contentful on the polish of the editor experience, particularly for large marketing teams used to enterprise-grade tooling. The community edition licence (SSPL) is fine for most uses but worth reading before shipping something commercial on top of it.

Contentful

The default when the primary users are a marketing team and the organisation is willing to pay for managed convenience. The editor UX is the strongest of the four for non-technical users, the App Framework covers the customisation most teams need, and the enterprise features are mature. It is not a fit when the content model is genuinely custom in ways the App Framework cannot express, when the licence cost at your entry and user count exceeds the value, or when data must stay in your infrastructure. Migration off Contentful is a well-known project shape and often the reason teams switch to Strapi or Payload.

Sanity

The default when the content itself is structured and editorial workflows are complex. Sanity Studio is customisable in a way the others are not, real-time collaboration is native, and the query language (GROQ) rewards teams who invest in it. It is not a fit when the team wants a simple document editor rather than a structured tree, or when the licence cost per user becomes a factor. Sanity's structured content thinking is a competitive advantage for the right team and a learning curve for the wrong one.

Payload

The default when the stack is modern Node.js and the developer team owns the CMS as much as the marketing team does. Payload is TypeScript-native, self-hostable, and the code-first schema definition suits teams that already work this way. It is the youngest of the four, so the ecosystem is thinner, but the direction of travel and the developer experience are strong signals. Worth shortlisting for any greenfield build on a modern stack, and worth being honest about the maturity gap for anything mission-critical.

Where each one breaks

• Strapi self-hosted with nobody owning the operations. Upgrades, backups and monitoring have to be someone's job.
• Contentful licence renewal after two years of growth. The bill that was fine at series A is a decision at series B.
• Sanity for a team that wanted "a nicer WordPress". It is not a nicer WordPress. It is a structured content platform with a learning curve.
• Payload for anything mission-critical without a fallback plan. The ecosystem is thinner, so integrations that exist for the others may need building.

Migration considerations

Migrating between headless CMSes is a project shape we see frequently, and the cost varies by content model rather than by content volume. The parts that add time: rich text formats that do not map cleanly, references and embedded blocks, media handling, published state and drafts, and any custom fields that leaned on vendor-specific features. Budget migration as its own phase with an owner on your side, and plan for a period of parallel operation. The full method sits in our custom business integrations and legacy system modernization guides, both of which apply here.

How to actually decide

Rank the four questions at the top by which matters most to your team. If hosting model matters most, the shortlist becomes Strapi or Payload. If editor experience matters most, the shortlist becomes Contentful or Sanity. Prototype the hardest content model on two of them, not the easiest, because the easy model always works on all four. Involve the editor who will use it every day, not the developer who will build it and move on. And write down the decision with the reasoning, so the next person who arrives can see why you chose what you chose.

If the decision points at custom instead, our build vs buy for internal software guide covers the maths, and custom web applications covers the shape of the engagement. For the operational side of running a self-hosted CMS, see DevOps consulting.

Frequently Asked Questions

What is a headless CMS?

A content management system that stores and delivers content through an API rather than rendering websites itself. The "head" (the front end) is separate, so the same content can serve a website, a mobile app, a set of digital signage and anything else that can call an API. It suits teams with multiple channels or a modern front-end stack.

Strapi vs Contentful, which should we pick?

Depends on who the primary editor is and how much control you want. Strapi if you value self-hosting, extensibility and licence cost control, and you have engineering capacity to maintain the platform. Contentful if the primary users are a marketing team, editor experience matters most, and you are comfortable with the licence cost as the team grows.

Is Strapi still open source?

Yes. The community edition remains open source under the SSPL licence, and the enterprise edition adds features such as SSO, audit logs and content history. The SSPL is more restrictive than MIT or Apache 2 for commercial redistribution, which matters if you plan to ship Strapi as part of a product; for internal use it is not usually an issue.

When does Contentful become too expensive?

The conversation usually starts in the low six-figure annual range, driven by a combination of entry count, user count and API request volume. The trigger event is often a new site or product being added, because entries and API calls both grow. Teams typically migrate to Strapi or Payload for cost control, not for missing features.

Is Payload production-ready?

For most content-driven applications, yes, and the trajectory is strong. It has been in production for years at credible teams. The honest caveat is that the ecosystem of third-party integrations, hosting providers and community plugins is smaller than for Contentful or Strapi, so integrations you take for granted with the others may need building.

Can we migrate off a headless CMS later?

Yes, and it is a common project. The cost varies by content model complexity rather than by content volume. Rich text formats, references, media handling and any vendor-specific features are the parts that take time. Budget it as its own phase and plan for parallel operation for a few weeks.

Do we need a headless CMS if we already use WordPress?

Not necessarily. WordPress can serve content via a REST or GraphQL API and be used headlessly, which is a lower-risk first step. Move to a purpose-built headless CMS when the WordPress data model becomes a limitation, when editorial workflows outgrow the interface, or when performance requirements exceed what WordPress can deliver.

How long does a Strapi build take?

A focused content backend with a defined schema and a front-end integration typically ships in 4 to 8 weeks. A larger implementation with several content types, custom workflows, plugin development and migration from an existing CMS usually runs 8 to 12 weeks. Migration cost depends on the source system, not on the target.
