When we first published this guide, choosing a headless CMS mostly meant comparing feature lists: which one had the nicer editor, the better API, the friendlier pricing page. That comparison still matters, but it's no longer the whole story, and the original version of this article had fallen well behind what's actually happening in the market.

Two things have changed since then. First, the industry is consolidating fast: two of the platforms we cover in this guide have been bought, or are in the process of being bought, by much larger companies. Second, AI has quietly rewritten the job description of a CMS. It's no longer just the place your team writes content; it's increasingly the structured source of truth that websites, apps and AI tools all draw from.

So this is a full rewrite. We build headless websites for a living, we work with these platforms daily on real client projects, and we'll tell you which ones we actually recommend, what we'd be cautious about, and how we make the call. We've written it for technical and non-technical readers alike, so we'll explain terms as we go.

A quick refresher: what a headless CMS is

A traditional CMS, like classic WordPress, bundles together content management and the presentation layer that displays it. A headless CMS deliberately separates them. It stores your content in a structured way and serves it through an API, which is simply a way for other software to request it. Your website, your mobile app, your digital signage and, increasingly, your AI tools all pull from the same source.

The practical benefits haven't changed: one place to manage content that appears everywhere, freedom to rebuild your front-end without touching your content, and the ability to structure content properly rather than trapping it inside page layouts.

What has changed is that last point's importance. Structured content used to be a nice architectural principle. In 2026 it's what makes your content usable by AI systems at all, whether that's an assistant answering customer questions from your product data or your own team using AI to draft, translate and audit content at scale. Messy, page-shaped content can't do any of that. Well-structured content can.

What's changed since we last wrote this

The acquisitions. In June 2025, Payload was acquired by Figma, the design tool most of the world's product teams already use. A year later, on 1 June 2026, Salesforce signed a definitive agreement to acquire Contentful, with the deal expected to close in the second half of 2026, subject to regulatory approval. On top of that, Sanity now counts Figma, Shopify and Anthropic among its customers, and every platform is racing to reposition around AI. When companies this large start buying content platforms, it tells you the category has become strategic. It also means "who owns this platform, and what do they want from it?" is now a real question to ask before you commit.

AI moved from gimmick to core feature. Two years ago, AI in a CMS meant a button that wrote mediocre blog intros. Now it runs much deeper. Sanity has repositioned itself as a "Content Operating System" with AI agents that can transform, audit and edit content across an entire dataset. Storyblok is building an AI assistant into its editor along with a semantic layer for deeper content understanding. "Strapi's AI, generally available since mid-2025, can generate a whole content model from a plain English description or even a Figma file. Some of this is marketing froth, but the underlying shift is real: platforms are being rebuilt on the assumption that both humans and AI systems will read and write your content.

Visual editing became the baseline. Editors have stopped accepting the old headless trade-off where you got a great API but wrote content into blind form fields. Every serious platform now offers some form of visual editing or live preview, where editors see the actual page as they work. The quality varies a lot, though, and for content teams it's often the single biggest factor in whether they love or hate the platform. We weigh it heavily in our recommendations.

The ones we recommend most often

We work with several of these platforms every week, for our own clients and as the development team behind other agencies. Two of them, Sanity and Payload, have become our clear first choices for most new builds, and we'll explain why. The other two earn their place for particular situations.

Sanity: the most capable, and our usual first suggestion

Sanity treats content as structured data more seriously than anyone else. Your content model is defined in code, everything is queryable through its GROQ language or GraphQL, and the editing interface, Sanity Studio, is a customisable application rather than a fixed admin panel. That flexibility used to be Sanity's main selling point. Its AI story is now just as compelling: agents that can make schema-aware edits across thousands of documents, automation that triggers when content changes, and first-class support for connecting AI tools directly to your content.

The honest trade-off is that Sanity gives you the most room to get things right or wrong. A well-modelled Sanity setup is a joy for editors and developers alike; a rushed one shows. It rewards teams (or partners) who invest in content modelling up front. Pricing is usage-based and the free tier is generous, but costs need watching on large, high-traffic projects.

Best for: teams who see content as core infrastructure, complex sites and products, and anyone who wants the strongest foundation for AI content operations.

Payload: the developer's choice, now with Figma behind it

Payload is open source, written in TypeScript, and installs directly into a Next.js application, which means your CMS and your website can live in one codebase. Developers tend to fall for it quickly: everything is code, everything is versionable, and there's no separate SaaS platform to configure. You can self-host it for the cost of your own infrastructure, which also makes it the strongest answer when data ownership or hosting location matters.

The Figma acquisition in 2025 raised eyebrows, but so far the commitments have held: Payload remains open source and self-hostable, "It is worth noting that Payload Cloud was discontinued for new projects following the acquisition, so self-hosting is now the primary path for new builds rather than an option, alongside a managed tier the founding team is still leading it, and the direction of travel is genuinely interesting, aiming to close the gap between what designers create in Figma and what ships on the web. It's the platform on this list whose next two years we're most curious about.

Best for: developer-led teams, projects that benefit from keeping the CMS and application in a single codebase, self-hosting requirements, and budget-conscious builds that still want modern tooling.

Storyblok: strong visual editing, with a flexibility ceiling

Storyblok's calling card is its visual editor: editors click on the actual page, edit in place, and compose pages from reusable blocks that developers define. For marketing teams coming from WordPress or a page builder, it offers a gentle landing, and it handles multi-language and multi-market setups competently. We've seen those strengths first-hand, having built our own SiteBeacon platform on Storyblok, where the editor experience and component-based approach have worked well for a content-led product.

That said, it's no longer the differentiator it once was. Visual editing has become table stakes across the market, and Sanity's has closed most of the gap while keeping a far more flexible foundation underneath. That foundation is why Storyblok has slipped down our list: its block-based model works well for page-shaped content but gets restrictive when content needs to be more deeply structured, feed multiple channels, or power the AI workflows we covered earlier. Increasingly, that describes the projects that matter.

Best for: straightforward marketing websites where in-page editing is the deciding factor, and multi-market content operations that fit its block-based way of working.

Contentful: the enterprise stalwart, with a big asterisk

Contentful more or less created the headless CMS category, and it remains a safe, mature choice: reliable APIs, a huge integration ecosystem, and the governance, roles and compliance features large organisations ask about first. Plenty of enterprises run very well on it.

For organisations already invested in Contentful, it remains one of the most mature enterprise platforms available. The asterisk is the Salesforce acquisition. Both companies have said Contentful will keep operating with the same platform, APIs and support, and there's no reason to panic if you're already on it. But the platform's future roadmap will inevitably bend towards the Salesforce ecosystem, and its pricing was already at the premium end of the market. If you're deep in Salesforce, that could turn out to be a genuine advantage. If you're not, we'd think carefully before starting a new long-term build on it until the dust settles.

Best for: large organisations with enterprise requirements, and especially those already committed to Salesforce.

Others worth knowing about

A few platforms didn't make our top four but deserve a mention, because in the right situation they're the right answer.

Strapi remains the best-known open-source option and has matured well: Strapi 5 is solid, the cloud offering keeps improving, and its AI tooling for generating content models is clever. We'd still pick Payload for most new self-hosted builds, mainly for the TypeScript-first developer experience, but Strapi is a reasonable choice with a large community behind it.

Prismic does one thing well: marketing websites built from reusable slices, with a workflow that keeps editors on the rails. If your needs fit that shape, it's good value. If they don't, you'll feel the walls sooner than you would with the platforms above.

DatoCMS is a well-built independent platform with loyal users, and there's something to be said in 2026 for a CMS that isn't owned by a giant. It's a sensible shortlist candidate for content-led sites.

Hygraph and Contentstack both target the enterprise end. Hygraph's GraphQL-native approach and content federation are useful when you need to stitch together content from many sources; Contentstack pitches itself as the composable answer to old-school enterprise suites. We see them less often than the big four, but they're credible.

And a word on headless WordPress: it can work, and for organisations with heavy WordPress investment it's a pragmatic stepping stone. But if you're starting fresh, we'd almost always choose a purpose-built headless CMS instead. You end up fighting WordPress's page-shaped view of the world to get the structured content that makes headless worthwhile

How we actually choose on real projects

Start with who's editing. The developers integrate the CMS once; the content team lives in it for years. If editors need visual, in-context editing to be productive, Sanity with its visual editing properly set up covers this well, and Storyblok is the alternative if in-page editing is the overriding priority. If the content is highly structured and the team is comfortable with forms and fields, the field opens up.

Then look at the shape of your content. A product with content woven through it, or content feeding multiple channels and AI systems, suits Sanity or Payload, where the content model is code and the structure can be exactly what your domain needs. A simpler marketing site made of pages can suit a block-based platform like Storyblok or Prismic, though we'd still weigh up whether the flexibility you give up is worth it, because simple sites have a habit of growing.

Then decide how much you want to own. Payload and Strapi can run on your own infrastructure with your data under your control. The SaaS platforms trade that ownership for convenience, and after the past two years of acquisitions, ownership questions deserve more weight than they used to get. Ask who owns the platform, what they want from it, and what your exit would look like: how easily could you get your content out and move?

And check the pricing at your real scale. Every platform has a friendly entry tier. The differences show up at scale: usage-based costs on high-traffic Sanity projects, per-seat costs as your Storyblok team grows, and enterprise contracts at Contentful that can jump sharply between tiers. Model the cost at the size you expect to be in two years, not the size you are today.

Our take

The headless CMS market in 2026 has split into platforms that treat AI as a feature bolted onto the side and platforms being rebuilt around structured content as the foundation for it. The second group is where we'd place our bets, because the direction of travel is clear: your content will be read by more machines, in more contexts, than ever before, and the platforms built for that will age best. That's also the honest argument for getting your content model right now rather than later; it's the part of the project that pays compound interest.

We've built with every platform in this guide across seven-plus years of headless projects, for end clients and as the development team behind other agencies. If you're choosing a CMS, or you're on one that the acquisition wave has made you rethink, we're happy to talk it through. Get in touch.
