Sanity CMS vs Contentful for Next.js projects: an honest comparison

When a client asks me to recommend a CMS for their Next.js project, the choice almost always comes down to Sanity CMS vs Contentful. Both are mature headless platforms with solid Next.js support, but they make very different bets on query language, pricing, and developer experience. I've shipped production projects on both, and the gap is more nuanced than the marketing suggests.

What you're actually comparing

Contentful is a SaaS-first platform. You get a hosted API, a structured content model editor, and a well-documented REST/GraphQL API. Everything is managed for you — schema migrations, Studio hosting, CDN delivery. That's the value proposition.

Sanity ships a content lake (the hosted backend) plus an open-source Studio that you own, configure, and deploy yourself. Schemas live in your repo as TypeScript files. You query with GROQ, a purpose-built query language. The Studio runs as a Next.js route or a standalone Vite app depending on how you wire it.

That distinction — schema-in-repo vs schema-in-dashboard — changes almost every downstream decision.

GROQ vs GraphQL: the real query language trade-off

This is where most developers form a strong opinion fast.

Contentful's GraphQL API is standard and predictable. If your team already knows GraphQL, you're productive on day one. Tooling like GraphQL Code Generator gives you typed responses with minimal config.

GROQ is Sanity's query language and, after a week with it, I find it meaningfully more expressive for content shapes. You can dereference, filter, slice, and project in a single query without nested fragment boilerplate. Here's a real GROQ query I use for a blog index:

// Used in: app/(blog)/blog/page.tsx
*[_type == "post" && defined(publishedAt) && !(_id in path("drafts.**"))]
  | order(publishedAt desc)[0...12] {
  _id,
  title,
  "slug": slug.current,
  publishedAt,
  "author": author->{ name, "avatar": image.asset->url },
  "categories": categories[]->{ title, "slug": slug.current },
  "lqip": coverImage.asset->metadata.lqip,
  "dimensions": coverImage.asset->metadata.dimensions
}

The equivalent in Contentful GraphQL requires separate authorCollection and categoryCollection queries or deeply nested fragments. It's not unmanageable, but it accumulates friction on complex content models.

The downside for GROQ: it's proprietary. New engineers need to learn it, and there's no ecosystem of generic tooling. Sanity TypeGen partially bridges this by generating TypeScript types from your queries, but you have to run it as part of your build pipeline.

Contentful GraphQL wins on ecosystem familiarity. GROQ wins on expressiveness for relational content.

Pricing for small teams in 2026

This has shifted. As of mid-2026, Sanity's free tier gives you 3 users, 2 non-admin users, and a 500k API CDN request per month limit with 10 GB bandwidth. Their Growth plan starts around $15/month per seat.

Contentful's free tier is more generous on seat count (5 users) but caps content types at 48 and API calls at 1M per month on the Community plan. Their Basic plan starts around $300/month flat, which jumps hard for small teams.

For a freelance engagement with 2–4 editors and a modest content volume, Sanity is cheaper by a wide margin. For enterprise teams already on Contentful with existing contracts, switching cost outweighs the savings.

The Sanity free tier is also genuinely usable for client handoffs — I regularly leave clients on the free plan for low-traffic sites.

Next.js integration DX

Both platforms have official Next.js packages. The experience differs in meaningful ways.

Contentful's contentful npm package is typed but ships its own SDK with a non-trivial bundle size. Fetching content in an RSC looks clean, but you lose granular control over caching because you're going through their SDK rather than native fetch.

Sanity's next-sanity package wraps the Sanity client and plugs directly into Next.js's fetch cache with revalidate tags. This matters for ISR. Here's what a cache-tagged fetch looks like:

// app/(blog)/blog/[slug]/page.tsx
import { sanityFetch } from '@/sanity/lib/fetch'
import { postBySlugQuery } from '@/sanity/lib/queries'
import type { PostBySlugQueryResult } from '@/sanity/types'
 
export default async function PostPage({ params }: { params: { slug: string } }) {
  const post = await sanityFetch<PostBySlugQueryResult>({
    query: postBySlugQuery,
    params: { slug: params.slug },
    tags: [`post:${params.slug}`],
  })
 
  if (!post) return notFound()
 
  return <PostLayout post={post} />
}

The tags array maps directly to on-demand revalidation from a Sanity webhook. Contentful can do tag-based revalidation too, but it requires more manual wiring through their webhook payload.

Sanity also wins on Portable Text. Contentful's Rich Text requires @contentful/rich-text-react-renderer, which outputs relatively flat HTML. Sanity's Portable Text lets you map block types to custom React components — useful when editors need inline callouts, embedded components, or custom image crops inside prose.

Where Contentful wins

Contentful's content model tooling in the web UI is more approachable for non-developers. A content strategist can add a field without touching code. For teams where the CMS owner is not a developer, that matters.

Contentful also has stronger built-in localization support at the field level, a more mature roles and permissions system, and a larger library of third-party integrations (AI assistants, DAM connectors, translation workflows). If you're building for a mid-market brand with a dedicated content ops team, Contentful's workflow features justify the cost.

Where Sanity wins

Schema-in-repo is the right model for teams that treat content structure as part of the codebase. You get version control on your schema, environment-specific studios, and type safety from TypeGen. For a developer-led team, this is a significant productivity edge.

The Studio is also genuinely customizable. Structure Builder, custom input components, and document badges let you shape the editorial experience for your specific content model — not the other way around.

For Next.js specifically, the combination of GROQ's join capabilities, native fetch cache integration, and Portable Text's component mapping makes Sanity the more productive platform for complex page architectures.

How I decide on a new project

Three questions:

1. Who owns the content model long-term? Developer-owned → Sanity. Marketing/content ops → Contentful.
2. What's the team size and budget? Under 5 editors on a lean budget → Sanity free tier covers it. Large team with compliance needs → Contentful's enterprise tier might already be the choice.
3. How complex is the content graph? Many cross-references, portable text with custom blocks, image focal points → Sanity's tooling handles this more gracefully.

Neither platform is wrong. They serve different principals. But for Next.js projects built by a small developer-led team, Sanity's schema-in-code model and GROQ's query expressiveness usually win on the work that actually matters.
