Headless CMS vs WordPress

WordPress runs 40.3% of all websites, according to W3Techs. Both sides of the headless CMS vs WordPress argument love quoting that number. One side reads it as proof that WordPress is the safe choice. The other reads it as proof that WordPress is old software coasting on its install base. It proves neither.

Market share tells you how easy it is to find a plugin or a developer. It says nothing about whether your site will load quickly on a phone in Plovdiv, how often someone will have to patch it, or what it will cost to run in its third year. Those questions decide the matter, and the answers depend more on your team than on the software.

We wrote this for the business owners and marketing leads who have to sign off on the choice. If the word "headless" is still fuzzy, our plain-English guide to headless CMS covers the basics in a few minutes.

You are choosing between three setups

The debate is usually framed as a two-horse race. In practice you are picking one of three setups, and most comparisons skip the middle one.

• Traditional WordPress. One system stores your content, runs the admin dashboard and builds the pages visitors see, using a theme and plugins. Install it on hosting and you have a working site. Most of that 40.3% runs this way.
• Headless WordPress. Your team keeps the WordPress dashboard, but WordPress stops building pages. It hands content to a separate front end, usually built in Next.js, through the REST API that ships with WordPress core or through a plugin called WPGraphQL.
• A native headless CMS. Tools such as Sanity, Storyblok, Contentful or Strapi were built for this from day one. They store structured content and serve it through an API to a front end you build separately. There is no theme, no plugin directory and no page rendering built in.

The first option is a product you install. The other two are an architecture: a content store, a front end, and a developer joining them together. Almost every difference below comes back to that.

Speed: what the field data says

The HTTP Archive's Web Almanac 2024 looked at millions of real sites using data from Chrome users. On mobile, 40% of WordPress sites passed all three Core Web Vitals in 2024, up from 28% the year before. Drupal came in at 56%, Wix at 57% and Squarespace at 60%. Even Joomla managed 45%. WordPress is improving fast, but it still trails all four.

Core Web Vitals are Google's measures of how quickly a page loads, how fast it responds to a tap and how much the layout jumps around while loading. Google uses them as a ranking signal. On WordPress the usual culprits are heavy themes, page builders and plugins. A chat widget or a pop-up tends to load its own scripts and styles on every page, whether that page uses them or not.

Cheap shared hosting adds its own delay. WordPress assembles each page when someone requests it, and on a busy shared server that takes longer. A caching plugin helps, and it is one more thing to configure and keep an eye on.

Headless sites don't show up as a single row in that data, because headless isn't one platform. The speed comes from the front end. A Next.js site that pre-renders pages and serves them from a CDN starts fast. A badly built one is slow in ways no CMS can rescue. The fair summary: WordPress can be fast if someone works at it and keeps working at it, while a well-built headless front end is fast on launch day and stays that way unless someone breaks it.

For a local business the mobile figure is the one to watch. A big share of your visitors arrive on a phone, often on mobile data, and a slow first load loses them before they read a word of your offer.

Security: where the risk sits

WordPress core is well looked after. Patchstack's State of WordPress Security in 2025 counted 7,966 new vulnerabilities across the WordPress ecosystem in 2024, and only seven of them were in core. Plugins accounted for 96%. Of the total, 43% could be exploited without logging in, and a third had no fix available by the time they were made public.

So a WordPress site is as secure as its least maintained plugin, and business sites tend to collect plugins over the years. Keeping one safe means somebody checks for updates every week, tries them on a staging copy before they go live, and deletes the plugins nobody uses. Plenty of sites skip that routine for years because nothing looks broken. Then one day something is.

A native headless CMS removes most of that surface. The content sits with a hosted provider, the public site is a set of pre-rendered pages, and there is no wp-admin login screen for bots to hammer. You still have work to do. API keys can leak and the front end has its own dependencies to keep current. The list of things that can go wrong is just much shorter.

Headless WordPress lands in between. Visitors never touch WordPress directly, which helps. The back end still runs plugins, though, and those still need patching.

Editing: what your team lives with every day

This is WordPress's best argument, and it is a good one. The dashboard is familiar, the admin is available in Bulgarian, and your marketing person has probably used it at a previous job. Adding a page, scheduling a post or swapping a banner takes minutes, and nobody has to call a developer.

A native headless CMS gives editors a tidier interface built around structured fields. A product has a name, a price and a gallery, each in its own box, which makes it harder to break a layout by accident. Most of these dashboards are English-first. Some, like Storyblok, add a visual editor with live preview. Others show a form with a preview in a separate tab, which some editors find less intuitive at first.

Think about who else touches the content, too. If sales staff, franchise partners or a translator edit alongside marketing, roles and approval steps start to matter. WordPress ships with basic user roles and relies on plugins for approval workflows. Most headless CMSs let you define custom roles, with review workflows often kept for paid plans.

Multilingual content is where headless often pulls ahead for businesses running a site in Bulgarian and English. Headless CMSs such as Contentful and Storyblok build translation into each individual field. WordPress needs a plugin such as WPML or Polylang. Those work, and they are one more thing to update.

We still build on WordPress when the editing team is the deciding factor. For Megamarket, whose marketing team publishes weekly brochures and updates store hours without a developer, we chose WordPress because the team already knew how it worked. Training took almost nothing.

Cost: where the money goes

If you compare launch prices, WordPress wins almost every time. The number that matters is what the site costs you over three years.

• Traditional WordPress: cheap hosting, a theme and a handful of premium plugins, several of which charge a yearly licence fee. The ongoing cost is maintenance: updates, backups, and the odd afternoon spent untangling a plugin conflict. If nobody pays for that work, you pay later for a hacked or broken site.
• Headless WordPress: all of the WordPress costs above, plus building and hosting a separate front end. You are paying for two systems. It is worth it when your team's attachment to the WordPress editor, or years of existing content, justify the premium.
• Native headless CMS: a higher build cost, because the front end is custom work. Running costs are usually modest. Most hosted headless CMSs have a free tier for small teams, with paid plans priced by seats, languages or usage, and hosting a pre-rendered business site costs little. There are far fewer updates to pay someone for.

For a small brochure site that changes a few times a year, WordPress usually costs less overall. For a site that brings in a real share of your sales, gets steady traffic or feeds more than one channel, the higher build cost of headless can pay itself back through lower maintenance and fewer emergency fixes. It needs time to do that, so it suits sites you expect to keep for several years. Our pricing page shows how we scope both kinds of project.

Headless WordPress: the middle path and its catch

Headless WordPress sounds like the best of both, and for some teams it is. Editors keep the dashboard, visitors get a fast modern front end, and years of existing content stay where they are.

The catch is that WordPress no longer builds the pages, so any plugin that changes what visitors see stops doing its job. Page builders, sliders, form plugins, cookie banners and much of what your SEO plugin does all have to be rebuilt or rewired on the front end. Editor preview needs custom work too. Behind the scenes you still run a full WordPress install, plugins and updates included.

It fits best when you already have a large WordPress site, an editing team that won't give up the dashboard, and a need for speed that can't wait for a content migration. If you are starting fresh, a native headless CMS is usually the cleaner option. We cover the front-end side of this in more depth in Next.js vs WordPress for business websites.

How to choose for a Bulgarian business

Choose traditional WordPress if most of these describe you:

• The site is mostly standard pages, a blog and a contact form.
• A non-technical person edits it every week and already knows WordPress.
• You want to launch within a few weeks on a modest budget.
• Someone, in-house or on a retainer, will keep the plugins updated.

Go with a native headless CMS if these sound more like you:

• Search and paid traffic drive your sales, so mobile speed shows up in revenue.
• You publish in Bulgarian and English, or plan to add more languages.
• The same content has to reach a website plus an app, a kiosk or a partner feed.
• You take payments or handle customer data and want a smaller attack surface.
• You want to redesign in a few years without migrating all your content again.

Consider headless WordPress only if you already run a big WordPress site and moving the content is the part you can't face yet.

One point specific to the Bulgarian market: finding someone to maintain a WordPress site here is easy. A custom front end on a headless CMS narrows that pool, so ask whoever builds it how the handover works and what happens if you part ways. We build bespoke marketing sites on both setups, and we think you should ask every studio that question before you sign.

The verdict

WordPress is still a sensible choice for a small business site edited by a non-technical team, as long as someone owns the maintenance. Its weak spots are well documented: slower mobile performance than rival platforms, and a plugin ecosystem that accounts for nearly all of its vulnerabilities. You can manage both. Neither goes away.

A native headless CMS is the better long-term choice for most businesses whose website is a sales channel, runs in more than one language or feeds more than one screen. It costs more to build and usually less to live with. Headless WordPress works best as a bridge for sites with years of WordPress content behind them. If you are still torn, decide on two things: who edits the site, and how much of your revenue depends on it.

Frequently asked questions

Is a headless CMS better than WordPress for SEO?

The CMS won't rank you on its own. Content and links do most of that work. Headless helps on the technical side, because a well-built front end usually scores better on Core Web Vitals, which Google uses as a ranking signal. WordPress with a good SEO plugin handles the basics well but needs ongoing performance work to keep up.

Can I use WordPress as a headless CMS?

Yes. WordPress includes a REST API in core, and the WPGraphQL plugin adds a GraphQL API. Your editors keep the WordPress dashboard while a separate front end, often Next.js, renders the site. Expect to rebuild anything plugins used to handle on the front end, such as forms, sliders and page-builder layouts.

Is a headless CMS more expensive than WordPress?

To build, usually yes, because the front end is custom. To run, often no. Hosted headless CMSs have free or low-cost tiers for small teams, and you spend far less on plugin updates and fixes. The longer you keep the site, the more that running-cost difference counts.

Which is better for a site in Bulgarian and English?

Headless CMSs generally handle it more cleanly, with translation built into each content field. WordPress does it well through plugins like WPML or Polylang, and its admin is available in Bulgarian, which some editors value more than any argument about architecture.

Is WordPress still worth using in 2026?

For the right site, yes. It runs 40.3% of the web because it is quick to launch, cheap to host and easy to staff. The risk sits in unmaintained plugins, so either budget for regular updates or choose a setup with fewer moving parts.

Is Next.js a headless CMS?

No. Next.js is a framework for building the front end. It displays content but doesn't store or manage it. In a headless setup, Next.js is usually the part visitors see, and the CMS, whether that's Sanity, Storyblok or WordPress itself, is where your team edits.

How hard is it to move from WordPress to a headless CMS?

That depends on how tidy your content is. Standard posts and pages can be moved with scripts. Content locked inside page-builder layouts or shortcodes has to be cleaned up by hand, and that is where most of the effort goes. Some businesses go headless WordPress first, which gets them the new front end now and leaves the content move for later.
