decap-cms

Decap CMS (formerly Netlify CMS) is a content management system designed for websites built with static site generators. A static site generator is a tool that produces a finished website from files, rather than assembling pages on demand from a database. Decap CMS gives non-technical editors a clean, user-friendly dashboard to write and edit that content without touching code or files directly.

It works by embedding a small admin panel at the /admin path of your site. When an editor logs in and makes changes, those changes are saved back to the Git repository that holds your website's content — the same way a developer would edit a file and push it. You describe your content structure (what fields a blog post should have, for example) in a YAML configuration file, and Decap CMS generates the editing interface from that description.

You would use Decap CMS if you are running a Jamstack site (a modern website architecture where content is pre-built into static files) and you need to let clients, writers, or teammates update content without requiring developer access. It integrates with any static site generator and any Git host. The project is written in JavaScript, licensed under MIT, and can be added to a site by loading it from a CDN or installing it via npm.
