Keystatic

Keystatic is a TypeScript-first, file-based CMS that provides a first-class editing experience for Markdown, YAML, and JSON content in your codebase, with direct GitHub integration for collaborative editing.

🚀 Overview

Keystatic is a modern CMS designed to make content stored in Markdown, JSON, or YAML files easily editable by non-technical users through an intuitive web interface, all without requiring a database or external hosting.

It solves the common pain point for developers: enabling content teams to contribute to sites and apps without granting code access or managing complex CMS infrastructure. Instead, changes are saved directly to your local filesystem or pushed to GitHub as pull requests.

Built for developers working with frameworks like Next.js, Astro, and Remix, it's ideal for blogs, documentation sites, marketing pages, and any project relying on structured file-based content. Thinkmill Labs created it as an evolution of their KeystoneJS experience, prioritizing developer joy and simplicity.
