Sanity

This Sanity CMS review covers what Sanity is used for, its key features, Sanity pricing and quotas, how the studio and query language work, where it shines and falls short, and how it compares with other tools. Sanity splits a CMS into two parts: the Content Lake, a hosted database that stores every piece of content as structured JSON documents, and Sanity Studio, an open-source React application where editors create and manage content. Developers define the content model in code, and the website, mobile app or AI agent fetches content through the API. Because content is stored as data instead of pages, the same product description, author or FAQ can appear on many sites and channels without copy-paste.

What is Sanity used for?

Sanity is used by developers and content teams to run websites, e-commerce storefronts, documentation, marketing pages, mobile apps and multi-brand platforms from one source of structured content. A typical project pairs Sanity with a front-end framework such as Next.js, Nuxt or Astro: editors work in the Studio, the front end queries the Content Lake, and pages update in real time. Content reuse is the main reason teams pick it: a product, location or author is one document, referenced wherever it appears.

Sanity also targets content operations at scale. Larger teams use custom workflows, content releases, private datasets and roles to manage many editors across brands and languages, and newer AI features let agents read and write content through the same API.

Key features

• Sanity Studio: an open-source React editor that lives in your code repository. Developers configure fields, validation, previews and custom input components, then deploy it with one command; hosting for the studio is included on every plan.
• Content Lake: the hosted, real-time content database behind every project. Documents are JSON, references link documents together, and every change is versioned.
• GROQ: Sanity's query language filters documents, follows references and shapes the response in one query. GraphQL is available as well.
• Visual editing: the Presentation tool shows the live website next to the editing form, so editors click an element on the page to edit its field. It needs front-end integration work to set up.
• Real-time collaboration: several editors work in the same document at once, with presence and full history.
• Content releases and scheduling: group changes into a release and publish them together (an add-on on some plans).
• AI and agents: Content Agent handles content operations through Slack and the API, and Sanity publishes an MCP server so AI tools can query and update content (Cosmic).
• Security and compliance: SOC 2, GDPR and CCPA compliance are listed on the pricing page; SSO and custom roles belong to the enterprise plan.

Sanity pricing

Sanity has a free plan, a per-seat Growth plan and custom enterprise pricing. The figures below come from the Sanity pricing page as of September 2026.

• Free plan: $0 forever, with full access to the Studio and API. Up to 20 seats, 2 public datasets, 10,000 documents, 1M API CDN requests and 250,000 API requests a month, 100 GB of assets and 100 GB of bandwidth a month.
• Growth plan: $15 per seat per month, up to 50 seats; Sanity's Growth plan is where teams pay for private datasets and more user roles. Two private or public datasets, 25,000 documents, the same included quotas as Free, plus overage billing: $1 per 250,000 CDN requests, $1 per 25,000 API requests, $0.50 per GB of assets and $0.30 per GB of bandwidth.
• Enterprise plan: custom pricing, seats, datasets and quotas, with SSO, custom roles, an uptime SLA and dedicated support.

A seat is used by every user type except Viewer, so read-only stakeholders are free. New projects get a trial of paid features for a limited period.

The cost surprise to check is usage, not seats. API requests from a busy site or preview environment can pass the included quotas, and on Growth the overages are billed automatically. Extra datasets cost $999 each, a bigger document quota is a $299 add-on, and dedicated support and the Media Library are sold separately (third-party figure from Cosmic, a competitor). Cache API calls through the CDN and watch the usage dashboard before launch.

Sanity Studio, the Content Lake and the content model

Everything in Sanity starts with the schema. Developers write the content model in JavaScript or TypeScript: document types such as post, product or author, fields such as a title string, an image with metadata or an array of objects, validation rules and references to other documents. Sanity Studio reads that schema and builds the editing interface from it, so a new field in code appears in the Studio after the next deploy. Because the Studio is a React application, teams can add custom input components, dashboards and plugins, or embed the Studio inside their own app. Editors see a clean interface with only the fields they need, while the structured data stays reusable across every channel. On the front end, a client library fetches the data with a GROQ query; you import existing content from another CMS with the CLI or the API, and you keep full ownership of your data through exports.

Content Agent, AI agents and content operations

Sanity positions itself as a content operating system for the AI era. Content Agent is an AI assistant for content operations: editors reach it through Slack or the API to create and update content in bulk. Sanity also publishes an MCP server, so AI agents and coding tools can query and update content in the Content Lake. Every plan includes monthly AI credits (1,000 on Free, according to Cosmic). Evaluate the AI features on a test dataset first, because generated changes still need editorial review.

Is Sanity better than WordPress?

Sanity and WordPress solve different problems. WordPress is a traditional CMS where content, themes and the website live together, and a non-technical team can launch a site with themes and plugins. Sanity is a headless CMS and content backend: it has no themes or front end, so a developer builds the website with a framework and fetches content through the API. Sanity is better when content feeds several channels, when the content model is complex, or when editors need a custom workflow. WordPress is better for a simple site that a small team runs without a developer.

Where Sanity shines — and where it falls short

Strengths:

• Flexible content model defined in code, with strong content reuse through references.
• A fully customizable React studio and real-time collaboration.
• Generous free plan with 20 seats and hosted Studio.
• GROQ and a fast API CDN make complex queries simple.
• AI agents and an MCP server built into the platform.

Trade-offs:

• Needs a developer to set up the schema, Studio and front end; it is not a website builder.
• GROQ is another query language to learn.
• Usage-based overages make costs harder to predict for busy sites.
• Custom roles, SSO and private datasets beyond two require higher plans.

How Sanity compares

• Builder.io: a visual headless CMS with drag-and-drop page building for marketers.
• WordPress: the traditional CMS with themes and plugins, easier for non-developers.
• Webflow: a visual website builder with a built-in CMS for design-led sites.
• Ghost: a publishing and newsletter platform for blogs and memberships.
• HubSpot Content Hub: a CMS tied to HubSpot's CRM and marketing tools.

Contentful, Strapi and Payload are the most common headless CMS alternatives; Strapi and Payload are open source and can be self-hosted.

Is Sanity worth it?

Sanity is worth it for teams with developers who want full control over the content model and editing experience, and who publish the same content to more than one site, app or channel. The free plan is enough to build and launch a small project, and Growth is affordable per seat. It is less of a fit for teams without a developer, for a single brochure site, or when usage costs must be fixed in advance; a website builder or WordPress is simpler there. If you want help with a Sanity schema, Studio customization or a migration, the web agencies and developers on LowCodeDevs can take it on.
