Marble CMS

Most sites need somewhere to keep a blog, a changelog and the occasional product update, and most content platforms answer with a system far larger than the job. Marble keeps it to two pieces, a dashboard to write in and a REST API to read from.

Because it is headless, content goes wherever you fetch it. The team publishes example repositories for Astro, Next.js and TanStack Start, and the API stays framework agnostic, so any server rendered or statically generated site can consume the same posts.

The editor and the tooling around it cover the everyday work.

• Editing: a rich text editor for text, images and video, with drag and drop uploads and markdown import.
• Organization: posts sorted with tags and categories.
• SEO: dedicated fields, readability insights and AI-powered writing suggestions in the editor.
• Webhooks: content changes fire real-time events that trigger workflows elsewhere.
• Workspaces: separate projects keep their own users and their own content.
• Integrations: a Framer plugin, a Raycast extension and an MCP server.

Marble is released under the AGPLv3, and the contributing guide walks through local setup and database configuration for anyone running it themselves. The hosted service meters API requests and webhook events per plan, starting from a free tier, for teams that would rather not operate it.
