Sanity vs Contentful: Headless CMS Comparison

Sanity and Contentful are both headless content management systems — they store and deliver content through APIs rather than being tied to a specific frontend framework. Both serve content to websites, mobile apps, and any other platform that consumes structured data. Despite this shared category, they differ significantly in philosophy, pricing, and developer experience.

Contentful launched in 2013 and pioneered the headless CMS category. It's an enterprise-focused platform used by major brands including Spotify, Vodafone, and Urban Outfitters. Contentful's approach is a managed SaaS platform with a web-based content modelling interface and REST/GraphQL APIs for delivery.

Sanity launched in 2017 with a different model. The content is stored in Sanity's hosted Content Lake (their cloud backend), but the editing interface — Sanity Studio — is an open-source React application that you customise and deploy yourself. This means you can tailor the editing experience to your exact content workflow. As of 2026, Sanity's developer-friendly approach has attracted a large following, particularly among agencies and Next.js developers.

Sanity Studio is a React application that you clone, customise, and deploy. Schemas are defined in code (TypeScript/JavaScript), giving developers full control over content models, validation rules, and the editing interface. You can create custom input components, add previews that show content as it will appear on the live site, and build entirely custom workflows within the Studio. This code-first approach means version control, testing, and deployment follow standard software development practices.

Contentful's content modelling is configured through a web interface. You create content types, add fields, and set validation rules in the browser. This is initially faster than writing schema code, but the customisation ceiling is lower. Contentful Apps (extensions) allow custom field editors and sidebar widgets, but building these requires understanding Contentful's extension SDK and hosting the extensions separately.

For teams with development resources, Sanity's code-based customisation enables experiences that Contentful's web interface cannot match — custom preview panes, conditional field visibility, content workflows tailored to editorial processes. For teams wanting a functional CMS without development effort, Contentful's web-based setup is faster to get running.

Sanity's real-time collaboration is a standout feature. Multiple editors can work on the same document simultaneously, with changes appearing instantly — similar to Google Docs. The Content Lake supports real-time subscriptions, meaning frontend previews can update as editors type. This creates a smooth editing experience where content creators see their changes reflected on the live site within seconds.

Contentful uses a more traditional editing model. Documents are edited individually and saved or published as discrete actions. Contentful does not support real-time collaborative editing on the same entry — if two editors open the same content, one may overwrite the other's changes (Contentful warns about this but does not prevent it). Contentful's recent updates have improved this with better conflict resolution, but it still does not match Sanity's real-time model.

For editorial teams that collaborate frequently on content — newsrooms, marketing teams producing campaign pages, agencies managing client content — Sanity's real-time collaboration is a meaningful productivity improvement. For teams where content is typically edited by one person at a time, this difference matters less.

Pricing is where Sanity and Contentful diverge most dramatically. Sanity's free tier includes generous API usage (up to 500K API requests per month), 20GB bandwidth, and 10GB asset storage. The Growth plan at $15 per project per month adds more usage and features. The paid plans scale based on usage (API calls, bandwidth, assets) rather than user seats.

Contentful's free Community plan includes 5 users and 25,000 records. The Team plan starts at $300 per month for 20 users with higher usage limits. Enterprise pricing is custom and typically starts at $1,000+ per month. The jump from free to $300 per month is one of the steepest pricing cliffs in the CMS category.

For a mid-size project with 10 content editors and moderate content volume, Sanity might cost $15-99 per month. The same project on Contentful would cost $300+ per month on the Team plan. This pricing difference makes Sanity significantly more accessible for startups, agencies, and mid-size organisations. Contentful's pricing reflects its enterprise positioning — the platform is designed for large organisations where $300 per month is a rounding error.

Sanity uses GROQ (Graph-Relational Object Queries) as its primary query language — a purpose-built query language for content that is more expressive than REST parameters and simpler than GraphQL for most content retrieval tasks. GROQ queries can join documents, reshape data, and filter results in a single query. Sanity also supports GraphQL for teams that prefer it.

Contentful provides REST and GraphQL APIs. The REST API uses URL parameters for filtering and includes, while the GraphQL API provides typed queries. Contentful's Content Delivery API serves published content from a CDN, while the Content Preview API serves draft content. The API structure is well-documented and mature.

GROQ's expressiveness is a genuine developer experience advantage. Queries like fetching a page with its referenced author, related posts, and nested content blocks can be written as a single concise GROQ query. The equivalent Contentful REST or GraphQL query would require more verbose syntax or multiple requests. For developer teams comfortable learning a new query language, GROQ is a productivity boost.

Both platforms integrate well with modern frontend frameworks, but Sanity has particularly strong Next.js integration. The next-sanity package provides server-side data fetching, real-time preview, and visual editing capabilities that make Sanity the best-integrated CMS option for Next.js projects. Sanity's visual editing feature allows content editors to click on elements in the live preview and edit them in the Studio — a compelling editorial experience.

Contentful's ecosystem is broader with official SDKs for JavaScript, Python, Ruby, PHP, and other languages. Its marketplace includes apps and integrations for translation, asset management, and workflow automation. Contentful's Compose feature provides page-builder functionality that is popular with marketing teams.

For Next.js projects specifically, Sanity's integration depth makes it the natural choice. For projects using other frameworks or requiring multi-language SDK support, Contentful's broader ecosystem may be more relevant. Both platforms have active communities, extensive documentation, and professional support options.

For most projects in 2026, Sanity is the better choice. Its pricing is dramatically more accessible, the customisation depth through Sanity Studio enables superior editorial experiences, real-time collaboration improves team productivity, and the Next.js integration is best-in-class. GROQ is a genuine improvement over traditional CMS query approaches.

Choose Contentful if your organisation already has Contentful expertise and established workflows, if you need Contentful's specific marketplace integrations, or if enterprise procurement processes favour established vendors with longer track records. Contentful is a capable and mature platform — it is simply more expensive and less customisable than Sanity for comparable functionality.

For agencies building websites for clients, Sanity's per-project pricing and customisable Studio make it particularly attractive — you can create tailored editing experiences for each client without per-seat costs that scale with editor count. For enterprise content operations with complex approval workflows and multi-market localisation, evaluate both platforms against your specific requirements, as Contentful's enterprise features may justify the higher price.
