Sanity CMS: What It Is, Why Teams Choose It, and When Not To

What Sanity CMS actually is

Sanity is two things:

1. A hosted content backend. Your content lives on Sanity's servers as structured data, queryable through their real-time API (GROQ) or over GraphQL. You do not manage a database.

1. Sanity Studio, the editor UI. A React application you configure with a schema. Editors log into a rich, real-time interface to write, preview, and publish content. The Studio runs on your infrastructure; the content lives on Sanity's.

The split matters. Every headless CMS decouples content from presentation. Sanity goes further by making the editor UI itself configurable code. You are not stuck with someone else's UX for your editors. If your team edits case studies, you build the case study editor.

Why teams choose Sanity

Four reasons come up in every project we run on Sanity:

Structured content. Schemas are typed. A "case study" is not a free-form rich text field; it is a set of fields with references, validation, and shape. That structure travels to every consumer — website, app, PDF export, LinkedIn slot.

Real-time collaboration. Multiple editors work in the same document simultaneously without conflict. Sanity handles the CRDT plumbing. For teams where marketing and comms co-author, it removes a class of pain.

A configurable editor UI. You can build custom input components, preview panes that show the actual rendered page, and workflows tuned to your team. Non-technical editors get a UI that fits their job. Contentful and WordPress can't match this (see Contentful vs Sanity and Sanity vs WordPress for the detailed comparisons).

The developer experience. GROQ (Sanity's query language) is powerful and specific. TypeScript types can be generated from schemas. Deploy previews work naturally with Next.js. Engineers get out of Sanity what they put in.

When Sanity is the right choice

Sanity fits when:

• You have more than one editor and they need to collaborate

• Your content has structure (references, taxonomies, per-locale variants)

• You are on Next.js, Astro, Nuxt, or building a native app that needs an API

• Editors care about a proper editing experience, not just typing into a form

• You want typed content that engineers can trust

The sweet spot is a growing business (£2M-£25M revenue is where we see it land most often) with a marketing site, a product, and a content team. Sanity gives them one backend that feeds both the site and the app.

When Sanity is the wrong choice

Two situations where you should pick something else:

1. The site is a one-page brochure with a five-post blog. Sanity is overkill. Use Framer, Webflow, or Ghost. The set-up cost outweighs the benefit.

2. Your team wants to drag and drop the page layout, not the content. Sanity is a content backend. It does not do visual page building. If your marketer wants to move a section on the homepage without a developer, Sanity plus Next.js is not that. Look at Framer or Webflow instead.

What it costs

Sanity's free tier is generous. Two users, three datasets, 500k API requests a month. Real projects usually land on the paid tier: about $99 per project per month for the Growth plan, which unlocks more users, more datasets, and higher API limits. Compared to Contentful (starts at around $300/month for a comparable tier), Sanity is materially cheaper for the same job.

The stack it goes into

The default modern stack for a Sanity site:

• Sanity for content

• Next.js for the front end (App Router, TypeScript)

• Vercel for hosting, previews, and edge functions

• Tailwind for styling

• Motion for animations

That combination is what we ship most weeks. It gives editors a great UI, engineers a real codebase, and marketing a fast site that ranks.
