Sanity vs Contentful vs Strapi: Headless CMS Comparison for 2026

The headless CMS market is projected to reach $3.8 billion by 2028. Sanity, Contentful, and Strapi are the three most popular options, each with a different philosophy. Here is how they compare.

Quick Overview

Sanity

Strengths

Customizable Content Studio: Sanity Studio is a React application you own and customize. Build completely custom editing interfaces, workflows, and content structures. No other CMS offers this level of editorial customization.

GROQ Query Language: Sanity's proprietary query language is more expressive than GraphQL for content queries. Joins, projections, and transformations in a single query.

Real-time Collaboration: Multiple editors work simultaneously with real-time presence and conflict resolution. Google Docs-like editing experience for structured content.

Content Lake: Sanity stores content as structured data in a "Content Lake" — a real-time, hosted datastore. No schema migration headaches. Schema changes are non-destructive.

Portable Text: Rich text stored as structured data (JSON), not HTML. Render rich text in any format: web, mobile, email, PDF. Embed custom components within rich text.

Weaknesses

• GROQ has a learning curve (though it is powerful once learned)
• Customizing the Studio requires React knowledge
• Smaller ecosystem than Contentful
• Documentation can be fragmented

Pricing

• Free: 100K API requests/month, 3 users, 20GB bandwidth
• Growth: $15/user/month + usage
• Enterprise: Custom pricing
• Usage costs can be unpredictable at high scale

Contentful

Strengths

Enterprise-grade: SOC 2 Type II, ISO 27001, GDPR compliant. Used by large organizations (Spotify, Vodafone, Staples) that require enterprise security and compliance.

Content Models: Intuitive visual content modeling. Define content types, fields, validations, and relationships through the web interface. No code required for content model changes.

App Framework: Build custom apps that extend the Contentful interface. Sidebar widgets, field editors, and page apps. Growing marketplace of third-party apps.

Localization: Robust built-in localization. Field-level localization, locale management, and translation workflows. Strong for international content teams.

CDN Performance: Content API is backed by Fastly CDN. API response times are consistently fast globally.

Weaknesses

• Expensive at scale ($300/month minimum for teams)
• Content model changes can be destructive (require migrations)
• Less flexible than Sanity for custom editorial experiences
• Rich text (Rich Text field) is less powerful than Sanity's Portable Text

Pricing

• Free: 5 users, 2 spaces, basic features
• Team: $300/month (10 users, unlimited content types)
• Enterprise: Custom ($1,000+/month)
• Content Management API: Rate-limited by plan

Strapi

Strengths

Open-Source: Full source code access. Self-host on your own infrastructure. No vendor lock-in. Modify any part of the system.

Developer-First: TypeScript support, plugin system, custom API endpoints. Developers have complete control over the backend.

Self-Hosting: Run on your own servers. Data stays on your infrastructure. Critical for companies with data residency requirements.

Plugin System: Rich plugin ecosystem. Authentication (including SSO), email, media management, SEO, and more. Build your own plugins.

Cost at Scale: Self-hosted Strapi is free regardless of usage. No per-API-call charges. Hosting costs only.

Weaknesses

• Self-hosting requires DevOps expertise
• Cloud version (Strapi Cloud) is newer and less mature
• Performance depends on your hosting setup
• Content editing UI is less polished than Sanity or Contentful
• Community support (open-source) vs enterprise support

Pricing

• Self-hosted: Free forever
• Strapi Cloud: $99/month (1 project, basic)
• Strapi Cloud Pro: $499/month
• Strapi Cloud Enterprise: Custom

Performance Benchmarks

API response times (50th percentile):

*Strapi performance varies significantly based on hosting infrastructure and database optimization.

Developer Experience

Local Development

Sanity: sanity dev starts the Studio locally. Hot reload. TypeScript schemas. Excellent developer workflow.

Contentful: No local development for the CMS itself. Content modeling in the web UI. Local development for frontend only.

Strapi: Full local development. strapi develop runs the entire CMS locally. Database migration support.

TypeScript Support

Sanity: Full TypeScript support for schemas, queries, and Studio customization. sanity typegen generates TypeScript types from your schemas.

Contentful: contentful-typescript-codegen generates types from content models. Official TypeScript SDK.

Strapi: TypeScript support since v4. Auto-generated types. Fully typed API responses.
