Marble is a super-simple headless CMS focused on blogs, changelogs, and articles. You write and organize posts in a clean dashboard, upload images and videos that get served from a global CDN, and pull everything into your site via a straightforward API that works with Next.js, Astro, Nuxt, and any other framework. Realtime webhooks let you trigger external workflows whenever content changes, and an AI-powered readability score gives you optimization tips while you write.

It's transparently aimed at developers and small teams who want a CMS that just works for content-driven sites without the bloat of WordPress or Sanity. The free Hobby tier covers solo creators with unlimited posts, 1GB of media, and 10k API requests/month; the Pro plan is $200/year for teams. Marble is used in production by indie projects like OpenCut, BookFlow, and Helix DB, with public endorsements from makers at Unkey and Upstash.
