Tina CMS

Tina is an open-source headless CMS that keeps your content in Git alongside your code. It adds a visual editing layer on top of Markdown, MDX, or JSON files, so everything stays in your repository and you control hosting, deployment, and version history without a third-party CMS server.

It's built for development teams and static site builders (Astro, Next.js, Hugo) who want visual editing without external dependencies. The Git-backed model means content is versioned, reviewable in pull requests, and can live in the same workflow as your product code.
