Headless CMS Comparison From a WordPress Shop: Worth It or Not

Almost every headless CMS comparison you will find was written by a company that sells a headless CMS. Strapi ranks Strapi well. Sanity’s list puts Sanity at number one. The lists are not wrong, exactly, they are just selling. And they all quietly skip the question that actually matters for most businesses: do you need to go headless at all?

We build on WordPress, and we have also built headless front-ends on Next.js with WordPress, Strapi, and Sanity behind them. So we have no platform to push here, only a strong opinion about when the architecture pays off and when it is an expensive way to solve a problem you do not have. Here is the comparison, with WordPress treated as a real option rather than the thing headless fans tell you to leave behind.

What “headless” actually means

A traditional CMS like standard WordPress handles both jobs: it stores your content and it renders the pages visitors see. A headless CMS only does the first job. It stores content and hands it out through an API, and you build a separate front-end (usually in React, Next.js, or similar) to display it. The “head,” meaning the front-end, is detached from the “body,” the content store. That is the whole idea.

The pitch is speed and flexibility. One content source can feed a website, a mobile app, and a digital sign without duplicating anything. The cost is complexity: you now run and maintain two systems instead of one, and you need developers to change the front-end.

Why most headless comparisons are not very useful

Look at who ranks for “headless CMS comparison.” The first organic result is usually a Reddit thread, because developers trust other developers more than vendor marketing. Below that sits a stack of pages from Strapi, Sanity, Hygraph, and Storyblok, each comparing the field in a way that happens to favor the host. The feature grids look objective. They are advertisements with tables.

The other problem: these lists assume the decision is already made. They start at “which headless CMS,” never “should this project be headless.” For a marketing site or a blog, that skipped question is the only one worth asking, because the answer is often no.

The contenders, honestly

These are the platforms we actually see in client projects, and what each is good and bad at.

• Strapi. Open source, Node.js, free to self-host. Developers like it because the schema is code and the REST or GraphQL API appears instantly. The editing experience for non-technical people is plain, and you own the hosting headache. Strapi Cloud starts around $15 a month if you do not want to run it yourself.
• Sanity. Hosted, with a generous free tier and a React-based editor called Sanity Studio. Real-time collaboration is excellent and the structured content model is the best in the group. The catch is pricing that scales with API requests and seats, which can surprise you on a busy site.
• Contentful. The enterprise default. Polished, strong on localization and governance, and priced for companies with a procurement department. Small teams feel the cost fast once they outgrow the free tier.
• Storyblok and Prismic. The marketer-friendly middle. Both offer a visual editor so non-developers can see what they are editing, which solves the single biggest complaint about headless. Good fit for content teams that want headless speed without losing preview.
• Headless WordPress. Yes, WordPress is a headless CMS if you want it to be. It ships with a REST API, and the free WPGraphQL plugin gives you a GraphQL endpoint. You keep the editor your team already knows and the entire plugin ecosystem on the back end, then build the front-end in Next.js.

How they compare

Platform	Cost	Editor experience	Best for
Headless WordPress	Free core, plus two hosts	Familiar, plugins intact	Teams already on WordPress
Strapi	Free self-host, ~$15+/mo cloud	Plain, developer-set	React shops wanting full control
Sanity	Free tier, scales with usage	Excellent, real-time	Structured content at scale
Contentful	Expensive past free tier	Polished, enterprise	Large orgs with governance needs
Storyblok / Prismic	Mid-market plans	Visual editor for marketers	Content teams wanting preview

WordPress as a headless CMS

This is the option the vendor lists pretend does not exist. You run WordPress as the back end, where your editors keep Gutenberg, custom fields, user roles, and any plugin they rely on. The front-end is a separate Next.js app that pulls content through the WordPress REST API or WPGraphQL and renders fast static or server-side pages.

What you keep: the editing workflow your team already knows, the plugin back end, and one of the largest developer communities anywhere. What you lose: front-end themes and page builders, most front-end plugins, and live preview unless you add tooling like Faust.js to wire it back up. You also now maintain a WordPress host and a separate front-end host, usually Vercel or Netlify. It is more moving parts, and it is the most pragmatic headless path for a business that is already on WordPress and does not want to retrain its content team.

When headless is worth it, and when it is not

Go headless when you have a real reason. The honest ones we see: you are publishing the same content to a website and a native app and maybe a kiosk, so one API feeding many front-ends saves real work. You have an in-house React team that will own the front-end for years. You need page loads measured in milliseconds at large scale and have the budget to engineer for it.

Skip headless when the project is a marketing site, a blog, or a small store. People reach for headless to make WordPress faster, but a properly hosted WordPress site with a good cache hits the same speed targets for a fraction of the work. If speed is the only goal, fixing hosting and caching is the cheaper answer, and we wrote a whole guide on picking the best WordPress caching plugin for exactly that. Going headless to shave a few hundred milliseconds you could get from a cache plugin is paying a developer’s salary to avoid a $59 tool.

What we would actually recommend

If you are a content team already on WordPress and someone is selling you on headless for speed, push back and ask what specific problem it solves. Nine times out of ten the honest answer is performance, and there is a cheaper fix. If you genuinely have multiple front-ends or a dedicated React team, headless WordPress lets you keep your editors happy while your developers get their API, which is usually the lowest-friction path. If you are starting fresh with no WordPress baggage and a developer-first team, Strapi or Sanity are both excellent and worth a real trial.

Whatever you pick, the architecture should follow the requirement, not the trend. If you want a second opinion before committing a budget, that is the kind of thing we talk through on our WordPress development projects, and we have talked more than one client out of headless when it would not have earned its cost. For a broader platform view, our WordPress vs Drupal benchmarks cover the same trade-offs at the CMS level.

FAQ

What is a headless CMS?

A headless CMS stores your content and serves it through an API, without rendering the pages itself. You build a separate front-end, usually in a framework like Next.js, to display that content. It is “headless” because the front-end is detached from the content store, unlike a traditional CMS that does both.

Can WordPress be used as a headless CMS?

Yes. WordPress includes a REST API out of the box, and the free WPGraphQL plugin adds a GraphQL endpoint. You run WordPress as the back end and build a separate front-end that pulls content through one of those APIs. Your team keeps the familiar editor while developers get a modern front-end stack.

What is the best headless CMS?

There is no single best, only the best fit. Sanity leads on structured content and real-time editing, Strapi on self-hosted developer control, Contentful on enterprise governance, and headless WordPress on keeping a familiar editor. The right choice depends on your team and whether you have a genuine reason to be headless at all.

Is headless WordPress faster than regular WordPress?

Often, because a static or server-rendered front-end can be very fast. But a well-hosted traditional WordPress site with proper caching reaches similar load times for far less effort. Headless wins clearly on speed only at large scale or when you serve multiple front-ends, not as a quick fix for a slow brochure site.

Is a headless CMS worth it for a small business?

Usually not. Headless roughly doubles the build and maintenance work and requires developers for front-end changes. For a typical small business site, traditional WordPress is cheaper to build, easier to edit, and fast enough with good hosting. Headless earns its cost when you have multiple channels or a dedicated dev team, not before.

Headless CMS vs traditional CMS, what is the difference?

A traditional CMS stores content and renders the website in one system. A headless CMS only stores content and delivers it by API, leaving the front-end to a separate application. Traditional is simpler and cheaper to run; headless offers more flexibility across channels at the cost of added complexity and developer dependence.
