Headless CMS Comparison: Strapi, Sanity, Contentful, and TinaCMS

Choosing the right headless CMS is one of the most consequential technical decisions a development team can make. With Strapi, Sanity, Contentful, and TinaCMS emerging as the frontrunners, each platform brings distinct trade-offs in pricing, developer experience, content modeling, and scalability. This comparison breaks down the four platforms so you can match the right CMS to your project's needs.

Content Modeling and Flexibility

Strapi offers a self-hosted, open-source approach where content types are built through an admin UI or API. Its plugin marketplace extends functionality for SEO, media optimization, and internationalization. Strapi v5 introduced a new Draft & Publish system and improved lifecycle hooks, but its relational query performance can degrade with deeply nested content structures.

Sanity treats content as structured datasets rather than pages. Its GROQ query language lets you slice and project content with precision — a major advantage for omnichannel publishing. Sanity's Portable Text specification provides a block-content format that is richer and more predictable than typical WYSIWYG output, making it ideal for complex editorial workflows.

Contentful pioneered the headless CMS category and remains the strongest choice for enterprise teams that need robust roles and permissions, SLA-backed uptime, and a mature app marketplace. Content modeling is field-based and strict, which reduces content chaos but can feel rigid for teams that prefer rapid iteration.

TinaCMS takes a different approach entirely — it is a Git-based CMS that edits your Markdown or JSON files directly. Tina's visual editing capability lets content authors click on elements in a live preview and edit them in-context, a feature none of the others offer natively.

Pricing and Hosting Considerations

Strapi is free and self-hosted, though Strapi Cloud starts at $29/month. You manage your own database, backups, and scaling. Sanity's free tier includes 3 user seats, 20 GB of bandwidth, and 100 GB of asset storage — generous for small teams, but pricing grows with usage. Contentful's free Community plan caps at 50,000 records and 2 users, while enterprise plans quickly reach hundreds or thousands per month. TinaCMS is open-source and free; Tina Cloud starts at $25/month for media management and visual editing.

For budget-conscious projects, Strapi or TinaCMS offer the lowest total cost of ownership. For enterprise compliance and SLA needs, Contentful is the safest bet.

Developer Experience and API Quality

Strapi provides a REST API out of the box with optional GraphQL. The plugin system means you can add features like email or SEO without deep custom code. However, Strapi's middleware layer is synchronous, which can complicate advanced caching strategies.

Sanity shines with its real-time collaboration — multiple editors can work on the same document simultaneously, changes sync via WebSocket, and the GROQ query endpoint returns only the fields you ask for. The Sanity Studio is a React application you can customize with your own components.

Contentful's Content Delivery API (CDA) and Content Preview API (CPA) are battle-tested at massive scale. Its GraphQL endpoint is robust, and the Management SDK gives programmatic control over content models. The developer experience is polished but opinionated.

TinaCMS's Markdown-based approach means content lives in your Git repository. This eliminates the synchronization problem entirely — your content is always in sync with your codebase. Developers can work with familiar tools like VS Code and Git workflows.

When to Choose Each Platform

Pick Strapi when you need full control over hosting and want an open-source ecosystem without vendor lock-in. Pick Sanity when your content needs to appear across multiple channels (web, mobile, digital signage) and you need a flexible query language. Pick Contentful when you're in a regulated enterprise environment requiring SLAs, compliance certifications, and mature role management. Pick TinaCMS when your team prefers Git workflows and wants visual in-context editing for content authors.
