Sanity vs WordPress compared honestly. Editor UX, performance, cost, developer experience, and when each is the right pick for a growing business.
Here is the honest comparison, from an agency that ships both when the project calls for it.
The philosophy gap
WordPress is a monolithic CMS. The backend (PHP), the database (MySQL), and the front end (a theme) are one system, all running on the same server. You install plugins to add capability.
Sanity is a headless CMS. The content backend is separate from the front end. Your website (built in Next.js, say) fetches content from Sanity's API.
Everything else follows from that.
Editor experience
WordPress uses the Block Editor (Gutenberg). It has improved dramatically since 2018 but still feels like editing a page, not editing content. Editors often need training to avoid breaking the page layout.
Sanity Studio separates content from layout. Editors write structured content; the layout is handled by the front end. There is no way to "break the design" by editing text. The Studio UI is configurable to your team's workflow.
Verdict: For teams that publish weekly and value editor safety, Sanity is materially better.
Performance
WordPress, out of the box, is slow. Fast WordPress exists (managed hosting, aggressive caching, minimal plugins) but it takes work.
Sanity + Next.js, out of the box, is fast. Static generation, edge caching, and no plugin bloat. Core Web Vitals scores are consistently higher.
Verdict: Sanity plus Next.js wins on performance without effort.
Developer experience
WordPress: PHP, theme files, hooks, filters, and a plugin ecosystem where quality varies wildly. Modern developers rarely reach for it as a first choice.
Sanity + Next.js: TypeScript, React, GROQ queries, generated types, git-versioned schemas. Familiar to any developer working in modern web stacks.
Verdict: For anyone hiring engineers, Sanity is the stack developers actually want to work in.
Security
WordPress is the largest attack surface on the internet. Plugins introduce vulnerabilities. Sites need active patching. Managed hosts (WP Engine, Kinsta) mitigate but do not eliminate this.
Sanity + Next.js has a much smaller attack surface. The front end is static or serverless. The CMS is hosted by Sanity, patched by them. Custom code you write is where risk sits, and it is contained.
Verdict: Sanity is materially safer for a business that cannot afford a breach.
Cost
WordPress is nominally free. Real cost is hosting (Kinsta, WP Engine, ~$30-$300/month), premium plugins (~$500-$2000/year), and maintenance retainer.
Sanity + Next.js: Sanity Growth ~$99/project/month. Vercel hosting starts at $20/month for Pro. No plugin licences.
Verdict: Total cost of ownership is roughly the same at small scale. Sanity wins at higher scale because there is no plugin licence sprawl.
When WordPress is still the right choice
Three scenarios:
You need WooCommerce. WordPress plus WooCommerce is still the cheapest way to run a small ecommerce site. Sanity plus Next.js plus Shopify or Stripe is usually better above a certain scale, but for a first store, WordPress is a legitimate choice.
You have a specific plugin dependency. Some niche functionality (LMS, membership sites, specific integrations) has a WordPress plugin and no equivalent elsewhere.
The team already runs WordPress and rebuilding is more expensive than living with it. Sunk cost is real. Sometimes the answer is to stay.
When to migrate to Sanity
Your WordPress site is slow and you have tried the usual fixes
Editors are afraid of breaking the layout
You are hiring engineers who don't want to touch WordPress
Security has been a problem
The plugin sprawl has become unmaintainable
Marketing wants to move faster than WordPress lets them
What a migration actually looks like
A typical WordPress-to-Sanity migration for a growing UK business:
Content model design in Sanity based on the WordPress content
Content migration script from WP REST API to Sanity
Front-end rebuild in Next.js using the existing design or a refresh
Redirect map from old URLs to new (SEO preservation is critical)
Editor training on Sanity Studio
Cutover with monitoring
Typical timeline: 6-10 weeks depending on content volume and design decisions.

Frequently Asked Questions (FAQs)
Is Sanity better than WordPress?
For most new marketing sites, yes. Faster performance, safer security, better editor UX. WordPress still wins for WooCommerce and specific plugin-driven needs.
Should I migrate from WordPress to Sanity?
Yes if the WordPress site is slow, plugin-sprawled, hard to hire for, or the editor experience is causing errors. Stay if WooCommerce or a specific plugin is load-bearing.
Can Sanity replace WordPress?
Yes, for content-driven marketing and editorial sites. No, for WooCommerce-heavy ecommerce (use Shopify or a Stripe integration instead).
Is Sanity faster than WordPress?
Yes, out of the box. Sanity plus Next.js on Vercel consistently beats managed WordPress on Core Web Vitals with no tuning required.
Is Sanity more secure than WordPress?
Materially, yes. Smaller attack surface, no plugin sprawl, Sanity manages backend patches. WordPress is the largest attack surface on the web.
What does WordPress do that Sanity doesn't?
Visual page editing with Gutenberg blocks, and WooCommerce ecommerce. Sanity is a content backend; layout goes through code.
How much does a WordPress to Sanity migration cost?
Priced to scope. A typical growing-business marketing site with a blog runs 6-10 weeks including content migration, redirect setup, and editor onboarding.
Does Sanity have plugins like WordPress?
Sanity has a plugin marketplace, but since the Studio is code, integrations are usually built natively rather than installed. Fewer plugins, less plugin rot.
