Marble CMS is an open-source, API-first headless CMS built for blogs. It pairs a Markdown writing surface and built-in media library with a REST API and first-party Next.js and Astro integrations, so a small team can publish posts from a focused dashboard and render them on its own site.[1][2]
Quick verdict
Small blog teams publishing on Next.js or Astro benefit most from Marble CMS. Its Markdown editor, media library, and framework integrations cover the whole path from draft to rendered post without assembling a separate stack. Teams needing visual page building, non-technical no-code publishing, or a proven large-scale track record should choose something else. If the publishing workflow is Markdown drafts rendered through your own frontend, Marble CMS fits; if editors must build pages visually, pick a visual-first CMS instead.[1][2][3]
Key features
Markdown editor with live preview Posts are written in Markdown with a live preview and autosave, plus word count and a distraction-free surface, keeping long-form drafting inside one focused tool.[1]
Built-in media library Images upload by drag and drop into a shared library with folders, so posts reuse assets without a separate storage service within the plan's storage allowance.[1]
REST API with API-key access Workspaces issue API keys that gate content reads, and the docs expose content API references plus webhook configuration for rebuilds and downstream automation.[1][2]
Next.js and Astro integrations Official SDK references and maintained example repositories show blog content flowing into Next.js and Astro sites, which shortens integration work for those two frameworks.[1][2]
Workspaces with roles Team plans add workspaces, member seats, and roles, plus granular API keys, so contractors or clients get scoped access instead of shared credentials.[1][2]
Scheduling and SEO fields Posts support scheduled publishing, SEO titles and descriptions, slugs, and duplication, covering the routine mechanics of a publishing calendar.[1]
Categories, tags, and authors Content organizes by category, tag, and author with an authors and users surface, which is enough taxonomy for single- and multi-author blogs.[1]
Hosted plans with a free tier The managed service runs a free tier alongside $5 Hobby and $20 Pro monthly plans with stated member, storage, API-call, and pageview allowances, so trying it costs nothing before committing.[1]
Who will love it
Markdown-native blog teams Authors who already draft in Markdown get live preview, autosave, and word count without leaving the publishing tool.[1]
Next.js and Astro site owners First-party references and examples map directly onto these frameworks, so integration is configuration rather than a custom client.[1][2]
Budget-conscious small publishers The free tier covers a solo blog and the $5 Hobby plan adds members and headroom, keeping early costs near zero.[1]
Who should avoid it
Visual page builders Teams expecting drag-and-drop layouts get a post editor and an API instead; visual composition is outside the product's scope.[1][2]
Non-technical solo publishers Rendering content still requires wiring the API into a frontend, so editors without developer help cannot ship a site alone.[1][2]
Large-scale or compliance-heavy operations No data-residency statement, SSO documentation, or enterprise support offering was found, which blocks regulated or large-team adoption.[1][2]
Integration and deployment
Framework delivery over REST Content APIs and SDK references target framework frontends generally, with maintained examples for Next.js and Astro covering the primary integration path.[1]
Self-run via compose-based stack The repository documents a compose-based local run needing database, storage, and email configuration; a production topology guide was not found.[1][2]
Questions worth asking
What is the best Marble CMS alternative for non-technical users?
If nobody on the team writes code, Ghost is the conditional pick: Marble's own comparison hub positions Ghost as the fuller hosted blogging surface while Marble targets API-driven publishing. This rests on the vendor's comparison framing, not an independent Ghost evaluation.[1]
Is Marble CMS really no-code?
