There’s no contest on raw numbers. WordPress powers roughly 42-43% of all websites globally in 2026. Craft CMS, by comparison, holds well under 1% of the CMS market, with an estimated 100,000 or so live sites worldwide.

That gap is real, but it doesn’t tell the whole story. Craft has never chased mass-market adoption. It’s a commercially licensed, developer-first CMS that’s deliberately positioned itself at the premium, agency-led end of the market rather than competing for DIY users. Market share here reflects positioning as much as merit, WordPress dominates the total addressable market Craft was never trying to serve.

This is one of the starkest differences between the two platforms. WordPress is free software with variable running costs. Craft uses a per-project commercial licence on top of free self-hosting, or a free tier when hosted on Craft Cloud.

Craft CMS pricing correct as of mid-2026. WordPress hosting costs vary by provider and site requirements.

This is Craft’s defining strength, and worth covering in its own right rather than folding into a general flexibility comparison. Craft’s field and entry-type system lets developers define exactly what a piece of content is made of before a single line of front-end code is written, and that structure is native to the platform rather than bolted on. Combined with Twig templating and a mature, native GraphQL API, Craft is regularly held up as one of the strongest options for headless and API-first builds, pairing cleanly with front-end frameworks like Next.js or Nuxt.

WordPress’s developer experience has improved substantially in recent years. Its REST API is solid out of the box, and the WPGraphQL plugin is mature and widely adopted for teams that want GraphQL specifically, with growing official support for headless setups through frameworks like Faust.js. The block editor’s structured data output has also made WordPress considerably more headless-friendly than it was even a couple of years ago.

The practical difference: Craft’s structured, API-first approach is native and consistent by design. WordPress’s is achievable, and increasingly good, but built from a stack of plugins and conventions layered on top of a platform whose core data model was never originally designed around structured content.

WordPress’s SEO ecosystem is unmatched in scale. Plugins like Yoast SEO or Rank Math give editors granular, largely code-free control over metadata, schema, sitemaps, and redirects, and the sheer size of the plugin ecosystem means there’s a tool for nearly any SEO requirement.

Craft takes a different route: SEO functionality comes through plugins like SEOmatic, which developers configure directly rather than editors managing through a dashboard-driven interface. It’s less immediately accessible to a non-technical editor, but developers who’ve worked with both often rate Craft’s SEO tooling highly for its precision.

On raw performance, Craft’s Twig templates compile to efficient PHP with no framework bloat by default, and its element query engine has been specifically optimised for content-heavy sites. WordPress can match this, but typically needs a caching plugin and careful theme selection to get there, performance on WordPress is achievable but not automatic.

For editorial teams who want SEO control without touching code, WordPress’s plugin-driven approach remains more accessible. For developers who want precise, code-level control over technical SEO, Craft’s approach has real appeal.

This comparison is more nuanced than headline vulnerability statistics suggest. WordPress’s sheer scale, over 59,000 free plugins built by thousands of independent developers, means it’s a bigger target, and the overwhelming majority of reported WordPress vulnerabilities originate in third-party plugins and themes, not WordPress core itself. Core WordPress security is genuinely solid and backed by a dedicated security team, but a poorly maintained plugin stack is a real and common risk.

Craft’s curated plugin marketplace, numbering in the hundreds rather than tens of thousands, gives it a smaller attack surface by design. Licensing and updates are managed centrally through the control panel, and Craft’s commercial model funds a dedicated team responsible for core security, rather than relying primarily on volunteer contributions.

Neither platform is inherently insecure. The practical difference is exposure: a well-maintained WordPress site with a lean, carefully chosen plugin stack is very secure, but the platform’s scale means there’s more low-quality third-party code in circulation to potentially install by mistake. Craft’s smaller, curated ecosystem removes some of that risk at the cost of having fewer ready-made options to choose from.

This is genuinely one of the closer calls in this series. WordPress wins on cost, ecosystem size, and accessibility for non-technical teams. Craft wins on structured content, developer experience, and long-term maintainability for complex, content-heavy platforms. Neither is the wrong answer, but picking the one that doesn’t fit your team’s actual working style will cost you down the line regardless of which platform you choose.

Whether you need a fast, cost-effective WordPress build or you’re evaluating whether your content complexity genuinely warrants a platform like Craft, we can help you make the right call, and build it properly once you do.
