Marble vs Sanity
Sanity is a structured content platform. You define content types in code, customize the editing Studio, and query everything with GROQ. Marble is a headless CMS built around posts, with an editor that works as soon as you sign up. The choice usually comes down to how much content modeling your project needs.
The short answer
Choose Marble when
- Your content is mostly articles, blog posts, and changelogs.
- Writers should get a ready editor on signup, with no schema or Studio to configure and deploy.
- You'd rather render HTML or Markdown than serialize Portable Text.
- You want pricing per workspace rather than per seat.
Choose Sanity when
- You need custom content types such as landing pages, products, or localized content, modeled in code.
- Several editors work on the same document at once. Sanity includes real-time editing and presence on every plan.
- You want visual editing, live previews, comments, tasks, or scheduled drafts.
- Your project needs high API volumes, GROQ or GraphQL queries, or a React editing app you can customize.

With Sanity
- 1Create a Studio with the Sanity CLI, starting from a template or a blank schema.
- 2Define or adjust a post schema in code, then deploy the Studio.
- 3Write the post in Studio, with others editing alongside you in real time.
- 4Query it with GROQ and render its Portable Text body with a serializer.
Moving from Sanity to Marble
- Export your dataset with the Sanity CLI. You get a gzipped archive of documents and asset files (Sanity docs).
- Convert post documents to Markdown. Portable Text needs a serializer; Sanity lists the maintained options in its Portable Text docs.
- Upload the .md files, one at a time or as a ZIP of up to 100. Marble creates a draft for each (import docs).
- Upload images to Marble's media library and update references in your posts.
- Content types other than posts don't map to Marble. Keep them where they are, or store simple metadata in custom fields.
Frequently asked questions
Common questions about choosing between Marble and Sanity.
Is Marble a Sanity alternative?
For blogs and article publishing, yes. Marble gives you an editor, media library, and API without defining schemas. For projects that need many custom content types, Sanity's flexibility fits better.
Can I create custom content types in Marble?
Not arbitrary document types. Every entry is a post with authors, a category, and tags. Custom fields add typed metadata to posts: text, number, boolean, date, rich text, select, and multi-select.
Does Marble support GROQ or GraphQL?
No. Marble has a REST API with query parameters for filtering and pagination, a TypeScript SDK, and an MCP server for AI agents.
Can several people edit the same post at once?
Not in real time. Marble workspaces support several team members with roles, but it doesn't have Sanity's multiplayer editing, comments, or tasks.
Which costs less, Marble or Sanity?
It depends on your team size and traffic. Marble charges per workspace: $5 a month for up to 5 members or $20 for up to 10. Sanity's Free plan includes 20 seats, and Growth costs $15 per seat per month. Sanity's plans also include far more API requests, which matters if your site calls the API on every page view.
