Sanity vs WordPress: which CMS should a B2B marketing team run in 2026?

Choose Sanity if your marketing team publishes structured content that gets reused: case studies that appear on several pages, product facts that feed the site and other channels, a site in two or more languages. It gives editors a studio shaped to your content, but always needs a separate front end, a host and a developer. Choose WordPress if you want one system for pages, plugins and publishing that your editors already know, or you already run a large WordPress site with WordPress developers in-house, and you accept that someone owns hosting, updates and plugins.

This compares content systems. Sanity is a headless CMS: it stores content and runs the editing Studio, while the site is a separate front end, usually Astro or Next.js, on a host such as Vercel, Netlify or Cloudflare. WordPress is all-in-one: editor, themes, plugins and page rendering in one PHP application. Our bias, stated once: we build on Framer, Webflow, WordPress, Next.js and Astro, we're an Official Framer Expert, and our own site runs on Astro + Sanity. Facts are as of October 2026. For the wider question, see headless CMS vs website builder; for every platform side by side, the 2026 platform comparison.

How do Sanity and WordPress compare at a glance?

What is the actual difference between Sanity and WordPress?

Sanity stores content as structured data; WordPress stores pages. The rest follows.

In Sanity, a developer defines the content model in code. A case study is a document with fields: client, industry, challenge, results, a quote, a logo. Editors fill those fields, and the front end decides where they appear: the case study page, a related-work strip on a service page, the Hebrew version. Developers query it with GROQ, Sanity's query language (GraphQL is also supported). The three latest fintech case studies:

*[_type == "caseStudy" && "fintech" in industries[]->slug.current]
  | order(publishedAt desc)[0...3]{ title, "slug": slug.current, summary }

Sanity's pricing page lists the Studio as an "Open Source editor built with React.js", with free Studio hosting on every plan, and the sanity package is MIT-licensed, now on major version 6. Because it is code, you shape the editing screens to your content; ours is embedded in our site at /studio.

WordPress is one application that edits, stores and renders pages. Editors build posts and pages from blocks in the block editor, the theme renders them on the server with PHP, and plugins add features: WordPress.com advertises "over 60,000 plugins" on its paid plans. The software is free under the GPLv2 or later and moves fast: 7.0 shipped in May 2026, 7.1 in August, the current release is 7.1.3 from 6 October (releases), and the roadmap plans 7.2 for December, the third major release this year.

Can WordPress run headless like Sanity?

Yes. The WordPress REST API lets you "bring your WordPress content into completely separate applications", so WordPress can feed an Astro or Next.js front end the way Sanity does.

It makes sense when you have years of WordPress content and trained editors, and want a faster or more controlled front end. The cost is two systems: WordPress still needs hosting and updates, and the front end needs a developer and a host. Plugins that change the theme's output, such as SEO tags or forms, no longer reach the new front end, so that work moves into code. Starting fresh and going headless anyway, we'd pick a CMS built for it; see headless CMS development.

Which is easier for marketing editors?

WordPress, for teams that want to compose pages themselves. Sanity, for teams that publish the same kinds of content again and again and want guard rails.

Sanity editors fill structured fields: title, summary, industry, results. They can't break a layout, because layouts live in code. With Visual Editing they see the real page next to the form and can "jump directly from the preview to the field being edited". It's on every plan, with quickstarts for Next.js and Astro, but a developer sets it up. Real-time editing and multiplayer presence are on every plan; comments, tasks and scheduled drafts start on Growth.

WordPress editors build pages from blocks for paragraphs, images, headings, lists and more, and the block editor docs note that "more can be added through WordPress plugins". Most marketers know it: W3Techs (third-party) puts WordPress on 39.6% of all websites. How far an editor can move things depends on the theme and its blocks.

Our own trade-off: moving our site from Framer to Sanity cost us on-canvas editing and instant publishing by a designer. Design changes are now code changes that go through a build (one to two minutes on our machine) and a deploy; posts, projects and copy stayed self-serve. More in a CMS your team can run.

Which handles multiple languages better?

Sanity, if languages are part of the business. Locales cost nothing extra, and the content model is the same in every language.

Sanity lists "Unlimited locales" on every plan, within a per-dataset attribute limit (2,000 on Free, 10,000 on Growth). Its localization docs describe two approaches using Sanity's own plugins: one document per language, or all languages inside one document. The front end builds the language routing and hreflang tags. Our own site works this way: about 300 indexable pages across English and a full Hebrew, right-to-left mirror at /he/, with hreflang between them.

WordPress's documentation says it "currently does not support a bilingual or multilingual blog out-of-the-box" (multilingual WordPress). You add a plugin: WPML costs €39 for one site, €99 for three or €199 for unlimited sites, covering the first year of updates and support; Polylang is free, with Pro from €99 a year. Both work, but the plugin becomes part of your content model, so choose it once.

What does each really cost per month?

On list prices the software gap is tens of dollars a month. The real cost is whose time you buy: a front-end developer for Sanity, an owner for WordPress updates and plugins.

Our estimate assumes one B2B marketing site in two languages, three people who edit and publish plus one developer, commercial use, and list prices in USD per month excluding tax, domains, design and build.

Sanity with Astro

• Sanity Growth: 4 seats at $15 = $60 a month (pricing). Viewer-role users are free.
• Hosting: Vercel Pro at $20 (Hobby is "restricted to non-commercial personal use only", per Vercel's fair-use guidelines), Netlify Pro at $20, or Cloudflare Workers Paid from $5.
• Second language: $0 in licences.
• Software total: about $65 to $80 a month, plus a developer for every new section type, layout change and upgrade.

WordPress

• WordPress.com Business: $25 a month billed yearly, $40 billed monthly (pricing). Self-hosted, the software is free and hosting is whatever your host charges; there is no official price to quote.
• Second language: WPML Multilingual CMS at €99 for the first year, or Polylang Pro from €99 a year.
• Editors: the WordPress software has no per-user licence. Premium plugins and themes are priced by each vendor.
• Software total: about $25 to $40 a month on WordPress.com Business plus about €99 a year for languages, and an owner for core, plugin, theme and PHP updates.

Can you run Sanity for $0? The Free plan allows 20 seats, 10,000 documents and two datasets, but only Administrator and Viewer roles, so every editor is an admin, and the datasets are public only. Public means, in Sanity's words, "everyone can query for content in the dataset without being authorized": anyone with your project ID and dataset name can read every published document. Drafts are excluded from those unauthenticated reads, and assets "are public on the asset CDN, even when the dataset is private", on any plan. If you keep anything private as a published document, such as leads or gated content, budget for Growth and a private dataset.

Is Sanity more secure than WordPress?

Neither is insecure by default. They put the maintenance in different places.

WordPress runs PHP and a database behind your site; its requirements are PHP 8.3 or greater, MySQL 8.0+ or MariaDB 10.11+, and HTTPS. Core minor and security releases update automatically by default, and new installs since 5.6 auto-update major releases too. Plugins and themes only auto-update "in special cases", although since WordPress 5.5 you can switch plugin and theme auto-updates on in the admin. The job is steady, not scary: keep the plugin list short, turn on auto-updates where you trust them, and name one owner.

With Sanity, the public site can be plain HTML on a CDN. Ours prerenders every page at build time; only the embedded Studio and a few API endpoints (forms, the AI check) run on demand. The work moves elsewhere: keep access tokens out of browser JavaScript, as Sanity's data safety docs warn, choose dataset visibility on purpose, and keep npm packages current. See who owns your website after launch.

Which is better for AI tools and agents?

Sanity has AI inside the editor; WordPress gets it through plugins.

AI Assist, on Growth and above, adds reusable instructions, translation, and image and alt-text generation to the Studio. Agent Actions are schema-aware AI operations on documents; the pricing page lists them on every plan, with 1,000 AI credits a month on Free and Growth, but the docs call them experimental. Structure helps: an agent fills "industry" and "results", not a blob of text.

On WordPress, Yoast SEO generates an llms.txt file for free, and Rank Math supports one that stays empty until you configure it. On our Sanity site we built llms.txt, JSON-LD on every page type and a Markdown version of every page in code. Google says "not all bots can run JavaScript", so serve content as HTML: an Astro front end prerenders it, WordPress builds it with PHP.

What we've seen on client projects

• Teams want to publish without us. "Can our team add case studies and blog posts ourselves?" is the recurring CMS question; CMS and self-editing came up in 21 of the 101 client conversations we reviewed from 2026. On Sanity our answer is a draft-to-live workflow: an AI agent in the CMS can pre-fill a new entry from a brief, and a person reviews and publishes it.
• Editors work in forms. On our own site, pages, projects, posts, testimonials and form submissions live in Sanity; submissions are stored as private drafts, never published. Editors use the form-based Studio, not a visual canvas.
• WordPress has a reputation. When clients compared platforms, WordPress came up as the option that needs plugins and maintenance. That's a cost to plan for, not a verdict.
• Moving off WordPress. We ask for CMS access: it finds hidden pages and existing redirects a crawl misses. See website migration without losing SEO.
• Our own path. Our Astro + Sanity site went live in October 2026, after a Next.js + Sanity attempt that never launched. The story: Framer to Astro and Sanity.

Which should you choose?

Pick Sanity when content is reused across pages, languages or channels and a developer stays on call. Pick WordPress when you already run it, need deep plugin features in one system, or your editors want to compose pages with blocks.

Sanity is the wrong choice when nobody will touch the code after launch, or the marketing team expects to change layouts weekly on its own; a visual builder suits that better (see Webflow vs WordPress). WordPress is the wrong choice when nobody owns updates, or when your content is really data that has to be reused across languages and channels.
