About Keystatic

Keystatic is a content management system that keeps content as Markdown, YAML, or JSON files in your own repository instead of in a database. It offers a TypeScript API and a visual editing interface, connects directly to GitHub, and does not alter your source code. It carries over ideas from Keystone, a previous project from the same team, Thinkmill. It is released under the MIT license.

It is designed for modern front-end frameworks such as Next.js, Remix, and Astro, and is meant to fit into existing developer workflows. Because content is plain files, it can be versioned, reviewed, and deployed along with the rest of a site, and editors who are not developers get a friendly interface to change it.

The README describes the project as experimental while it is being developed and points readers to keystatic.com, guides, templates, and the CLI to try it. Development of the monorepo requires Node.js 18 and pnpm. Keystatic suits developers building content-driven sites who want a lightweight CMS without running a separate backend.
